TH-cam is really much better when I find out that you guys have uploaded a new video, Thanks a lot. I'd really like a video about memory areas and pointers in s7-1200 and S7-1500 PLCs
Excellent! I barely could finish high school but I could understand everything in this video, because the explanation was brilliant! Now I can send my resume as an electronic engineer!
I'm quite a fan of your video tutorials. But in this one, one point is not entirely correct: double conversion UPS are not the most efficient version, quite the opposite. They offer the best power quality, since there is no interruption at all and the AC is newly generated, so no variations or harmonics from the grid are getting to the equipment. Even the frequency can be corrected or changed from 50 to 60Hz of needed. But this process of double conversion is not the most efficient, since it has permanently the losses of an AC-DC conversion plus the losses of a DC-AC conversion. A UPS with transfer switch has very little loses, as under normal operation no conversion is occurring. But you get all the power quality problems from the grid to the load. And you can not influence the frequency.
Thank you for your comments. You are correct about the differences in efficiency (~96% for line-interactive, ~90% for double-conversion), but this is rarely the decision point for selecting one over the other. As you indicated, there are specific advantages to the double-conversion design, which are necessary in particular applications. Both UPS designs provide efficient operation; >90% efficiency is very good for any electrical device.

A UPS has one or more rechargeable batteries inside. These batteries typically last 2-4 years, at which time, they need to be replaced. The batteries are modular and can be removed and replaced fairly easily. Most can be recycled.
Wow, I bet those UPSs drain out pretty good when the wind ain't blowing. Even with the wind blowing you'd only have a very small percentage of what you really need to make things work. Due to this, I doubt the accuracy of your entire video. I'll stick with my APCs and Salem nuclear plant, thank you.
Wind power is just an example of where primary power can come from. Substitute the windmills with a nuclear or gas-fired turbine. Our aim in this video is to demonstrate how a UPS works, and I may be biased, but I think we did a pretty good job.
The ups wouldn't drain out quickly... It depends on how much load you have and how many strings of batteries you have. You'll know how much time you have to properly shutdown whatever equipment that you are powering by the ups if needed
The battery charger shown in the video is a rectifier (definition of a battery charger). Thank you for pointing that out, as other readers may find this information useful!
An ups battery will burn for 3 days non stop if it has a minor problem. So extreme caution should be taken when using them. Similarly big computers. The fire cannot be stopped because it is an electric dc shot circuit. At least 50 metres gaps are required for usage. Any DC system is like that. Some of them can burst to a range of 2 miles. Similarly huge TVs. Don't ask me why again and again.
Sizing of UPS systems is based on load and required time for supplying backup power. A simple way to do this is to add up the loads (in VA or Watts) of all connected equipment and multiply by 1.2. Then go a UPS manufacturer's website and select a UPS that will output at least the total load that was calculated. Then, decide how many minutes of backup power is required, and select the desired model from the data given by the manufacturer. Most manufacturers can help you do the calculation, and many have "calculators" on their websites.
My co-workers at my job let me have a UPS battery like this to hook up my TV, game console, and Blu-Ray player at home for my own personal enjoyments in case the power goes out. I have a TrippLite Internet Office 550VA Ultra-Compact Standby 120V UPS, and got me wondering how long it lasts when the power goes down.
do standby USPs provide any additional protection from surges, voltage drops and instable supply for the load, in other words, could it be used as a protection means?
Hi Hamza, Thank you for your question. Yes, it can. But UPS power, depending on your load, will be limited until the batteries die. Regular UPS for backup use at home will last about 30 minutes. Many date servers have more significant UPS that can last as much as 2 hours. Those types of systems have a generator to back up the UPS.
@@realpars my question is about the case where the standby UPS is standing by, and the power is coming from the mains and not the battery, does the standby UPS provide any protection in this case?
Confused on how much wattage of the UPS I should buy, I have a high end gaming rig and here are my specs. CPU: ryzen 5 3600 RAM: T-force delta 2x8 16gb ddr4 3000mhz GPU: RTX 2060 SUPER 8gb PSU: SEASONIC 750W Do I need a UPS with a wattage higher than my PSU? Any advice would be appreciated!
A quick way to determine an adequate size for a UPS is to calculate the Volt-Amps required by each device. Multiple the service voltage by the amp rating (on the device nameplate) to get Volt-Amps. For a 750W device like you, considering a power factor of 0.9, you require about 850 VA. Add up all of the Volt-Amps for all devices to be added to the UPS and multiple that number by 1.2. That is the capacity of the UPS you will need. If the device you described is the only one to be put on the UPS, then a UPS of 1000VA would be satisfactory for about an hour of backup power. Don't forget monitors or other peripherals that will need power!
The UPS should be plugged in whenever the PC is powered on. If you power off the PC, you can power off the UPS, but you want to make sure the UPS is fully charged again before relying on it to provide backup power for the PC.

Pls inform do we need to keep ups switch on from switch board( switch off from powwer button) all the time even when we are not working on computer. Keeping switch on all the time affects internal part as ups get little hot. UPS ( APC BACK 600 IN).
The number of devices that are backed up by a UPS is not an important factor. The total connected load and the amount of time you desire the UPS to back up the load in case of a power failure is what is important. Of course, depending on the number of devices, you will need to have the means to plug in or connect all of the backed-up devices. In your case, an appropriately sized standby UPS wired directly to a set of distribution panels with either appropriately-placed hardwired or plug-in outlets would be recommended.
@@realpars I'm trying to build a project for where I work . I get constant power fluctuations and outages, worse these types of UPS are not easily available. So I'm having hard time to find it.
While the UPS is on-line, either on main or battery power, the static switch is in ‘Load On UPS’ state, connecting the inverter output of the UPS to the load. However, if a UPS fault should develop, causing either the voltage or frequency at the inverter output to exceed acceptable levels or an overload , the static switch changes over without power interruption to ‘Load on Bypass’. The circuitry is all sold-state, with voltage and current comparators determining the health of the UPS output. The static switch fails over to bypass power if a problem internally to the UPS is detected by these circuits.
@@realpars You've left a LOT out. He asked how it works. Lot's of UPS use different methods. Some fully rated solid state, some a mix of contactors and partially rated SCRS. You've not mentioned the two pairs of SCRS, (usually), or much else.
The concepts shown in the video apply to commercial and industrial UPS systems. The main difference is in size and capacity of the batteries and switching systems. Commercial office and home UPS systems are typically 1-phase whereas industrial UPS systems are typically 3-phase devices.
Hi, when my PLC program is running, sometimes there is a power failure. And the process ends directly, and the program cannot continue. Do I need to select PLC with back up battery? or maybe use UPS? Do you have solutions for this? Thank You
If the PLC has a battery backup, it should continue running the program if incoming power is lost. Sometimes it is difficult to know when the batteries are near depletion, so I prefer using a UPS to back up all PLCs and the network switches to allow the network to continue to operate during limited power outages. You may also want to consider backing up I/O racks as well, but unless you have a very large Rotary UPS backing up main power to the production areas, you won't be able to keep pumps and other equipment running even if the PLC program continues to run.
What about the power consumption of those three types of UPS? I have a 1Kav Online UPS and when I check with an energy monitor I feel it consume more electricity than it should be.
Every type of UPS consumes some power, even when not connected to the battery supply. On-line UPS systems, by their design, provide the highest level of protection against power loss but exhibit some power consumption during normal operation. If your "losses" are >10%, then there may be an issue with the incoming power (cycle variations, "dirty" waveform, etc.) that is switching your system to battery in order to maintain a "clean" power feed.
Slightly more. The UPS needs to consume power to keep its circuits alive. From past measurements, I have found that a fully-charged UPS with no loads connected can draw between 5W (newer UPS models and technology) to about 50W (much older, less efficient UPS packages). If the UPS provides 1500W at full load, then 5W is a small price to pay to keep your equipment running in case of a power outage.
@@realpars i currently have a 2000va, and i was given advise to connect the ups all the time. But one of my friend also told me that the ups charges like a phone charger?
Most laptops have a built in battery that acts as a UPS. A small office-grade UPS is a standby (offline) UPS which kicks in when the main AC power is lost.
Yes. The UPS would be recharged from of the electricity that is produced by the solar system. UPS's sized to power a modest home or cabin are not too large, but can be expensive. A 1500W UPS can cost up to $3000. If you have a refrigerator, TV or electric water heater or stove in the off-grid dwelling, you may need a much large unit or multiple units if these need to be operated during "dark" hours.
is the battery charger coming with rectifier in online and offline ups just like the double conversion ups?is there any battery charger in double conversion ups? please clarify it for me
The online and offline UPS with transfer switch uses a separate rectifier and charging circuit to charge the battery. The electronics in a double conversion UPS is a little different, but achieves the same result: charging the battery. In a double-conversion UPS, the DC current from the rectifier is usually reduced to keep the batteries from overheating or overcharging. So yes, a double-conversion UPS has a battery charging circuit, but it is different than the circuit used in a transfer-switch type UPS.
Would a UPS help protect against power problems like surges or poor wiring in a house? Sometimes my soundbar makes a loud popping noise when someone turns off a light switch in my house, and it also causes the lights to dim in my room. I'm worried about it damaging my computer. I also live in an area where there is constant storms/hurricanes and experience several power outages every year.
Yes, a UPS would help protect against the power problems you are experiencing. A UPS gives good surge protection as well as providing a backup for power outages. Make sure you have a UPS that will give you an adequate amount of protection (based on the wattage of your computer and the length of time the backup needs to provide power in the event of a power loss).
What if I plug in something that requires more wattage into my UPS' "battery and surge protection" sockets for the sake of not having "Surge only" sockets . Would it damage my equipment?
The UPS is only going to supply the power it is designed to supply. The device will try to pull as many watts as it requires to operate, usually not at the same level as its rating. You won't damage your equipment in most cases. If the device does not have enough power to run, it will either shutdown or go to a sleep state to protect itself, or in an extreme case, such as a device with a disk drive. it may act sluggishly or may malfunction, depending on the way it was designed to handle low power situations.
UPS systems will charge when the source of electricity is available. When the electricity source is interrupted, the circuit will automatically switch to provide stored power from the battery.
@@realpars Actually I wanted to know does the UPS need to charge separately by switching off the UPS power button or it is charged automatically while it is connected to power source???
Great question! A UPS only regulates the incoming power to its normal input voltage (120VAC). When building a PC, you need a power supply to meet the voltage demands of the PC motherboard electronics (normally 12VDC). The motherboard then regulates the supply to its components to other voltages (+/-5VDC, for example). A UPS cannot input AC voltage and output DC voltage like a power supply is designed to do.
Yes, but it depends on your application. You have to understand that an IPS is not for applications that require an un-interrupted power supply. An IPS can take 1 second or more to switch over. PLC's and other industrial equipment may fail or go a halt state with a switchover time of 1 second.
Online UPS provides power to the connected load from the inverter circuit of the UPS. Incoming power is rectified to DC to charge the batteries and then inverted back to AC to power the load. The UPS inverter circuit is always "on line". When a power outage occurs, the UPS switched from mains to battery power. For an offline UPS, mains power bypasses the battery on the way to powering the load. At the same time one branch of mains power is used to charge the battery. When a power outage occurs, the transfer switch opens and power is drawn from the battery/inverter.
Yes. That is the way they are designed. A UPS is kept online and inline, monitoring the power status, and when an outage is detected, it switches over to backup power, usually within one cycle (1/60th of a second).
Enrique is correct. UPS's and VFD's are very different electrical devices. Usually, UPS systems designed to supply AC to motors and drives are very large (rotary UPS) or alternatively, backup power can be provided for these large loads with generators.
You don't need to, but since UPS devices do draw current even when no loads are connected, you probably would want to. By the same token, UPS's have batteries which should not be allowed to fully discharge and set idle for long periods of time.

Yes. Battery chargers use a rectifier to convert AC to DC, and they have additional circuitry to limit current to the battery charging circuit.
Is it possible to run the UPS on a solar system for off the grid power for a house
Yes. The UPS would be recharged from of the electricity that is produced by the solar system. UPS's sized to power a modest home or cabin are not too large, but can be expensive. A 1500W UPS can cost up to $3000. If you have a refrigerator, TV or electric water heater or stove in the off-grid dwelling, you may need a much large unit or multiple units if these need to be operated during "dark" hours.
is the battery charger coming with rectifier in online and offline ups just like the double conversion ups?is there any battery charger in double conversion ups? please clarify it for me
The online and offline UPS with transfer switch uses a separate rectifier and charging circuit to charge the battery. The electronics in a double conversion UPS is a little different, but achieves the same result: charging the battery. In a double-conversion UPS, the DC current from the rectifier is usually reduced to keep the batteries from overheating or overcharging. So yes, a double-conversion UPS has a battery charging circuit, but it is different than the circuit used in a transfer-switch type UPS.
@@realpars thank you for the quick response😊
Please Do make a video on wapda inverter and conveter
Thanks for the topic suggestion, Hassan! I will definitely go ahead and forward this to our creator team. Happy learning!
Would a UPS help protect against power problems like surges or poor wiring in a house? Sometimes my soundbar makes a loud popping noise when someone turns off a light switch in my house, and it also causes the lights to dim in my room. I'm worried about it damaging my computer.
I also live in an area where there is constant storms/hurricanes and experience several power outages every year.
Yes, a UPS would help protect against the power problems you are experiencing. A UPS gives good surge protection as well as providing a backup for power outages. Make sure you have a UPS that will give you an adequate amount of protection (based on the wattage of your computer and the length of time the backup needs to provide power in the event of a power loss).
@@realpars Thank you very much for the reply, and help. =)
@@realpars I believe my power supply for my PC is 800 watts. What kind of ups would you recommend for it?
Could you make a video of what is an Industrial UPS?
Hi Rob!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
Does it protect against power surges?
Great job by you guys.. Thanx alot..
Thank you, Margam!
Like to know about Probes &Vibration Monitoring systems can you do a video on it
Thank you so much sir for your packaged information.
You are most welcome!
Much better than wikipedia!
What if I plug in something that requires more wattage into my UPS' "battery and surge protection" sockets for the sake of not having "Surge only" sockets . Would it damage my equipment?
The UPS is only going to supply the power it is designed to supply. The device will try to pull as many watts as it requires to operate, usually not at the same level as its rating. You won't damage your equipment in most cases. If the device does not have enough power to run, it will either shutdown or go to a sleep state to protect itself, or in an extreme case, such as a device with a disk drive. it may act sluggishly or may malfunction, depending on the way it was designed to handle low power situations.
When the electricity is available, does the UPS charge automatically?? Or should we need to switch off the UPS and charge it???
UPS systems will charge when the source of electricity is available. When the electricity source is interrupted, the circuit will automatically switch to provide stored power from the battery.
@@realpars Actually I wanted to know does the UPS need to charge separately by switching off the UPS power button or it is charged automatically while it is connected to power source???
@@anirbanjana2776 charged automatically while it is connected...
So..if I'm building a pc..Do you buy this instead of a power supply or do you get both?
Great question! A UPS only regulates the incoming power to its normal input voltage (120VAC). When building a PC, you need a power supply to meet the voltage demands of the PC motherboard electronics (normally 12VDC). The motherboard then regulates the supply to its components to other voltages (+/-5VDC, for example). A UPS cannot input AC voltage and output DC voltage like a power supply is designed to do.
GREAT EXPLANATION TAKES LOT OF TIME TO MAKE A INFORMATIVE VIDEO SO THAT EVERY ONE CAN UNDERSTAND
Thanks for your support!
@@realpars Hey! Good day! Please reply me back!
I'm interested in purchasing online ups for sound equipment, is it the right choice?
This video was wow thanks alot
Glad to hear that! Happy learning
Great video
Thank you, Simon!
Can i use an ips ( Instant power supply) instead of an ups?
Yes, but it depends on your application. You have to understand that an IPS is not for applications that require an un-interrupted power supply. An IPS can take 1 second or more to switch over. PLC's and other industrial equipment may fail or go a halt state with a switchover time of 1 second.

Excuse me,what is defference between UPS online and offline?
Online UPS provides power to the connected load from the inverter circuit of the UPS. Incoming power is rectified to DC to charge the batteries and then inverted back to AC to power the load. The UPS inverter circuit is always "on line". When a power outage occurs, the UPS switched from mains to battery power. For an offline UPS, mains power bypasses the battery on the way to powering the load. At the same time one branch of mains power is used to charge the battery. When a power outage occurs, the transfer switch opens and power is drawn from the battery/inverter.
thank you for this :))
You are very welcome!
IPS system
the best
Thaaank youu sir
You are very welcome!
Thanks
Awesome! Thank you
You're very welcome!
Can UPS plug in the whole time ?
Yes. That is the way they are designed. A UPS is kept online and inline, monitoring the power status, and when an outage is detected, it switches over to backup power, usually within one cycle (1/60th of a second).
@@realpars Thanks bro.

Can we get a variable frequency drive that is also a UPS?
NO, a UPS must keep the frequency fixed to say 50Hz in Europe.
Enrique is correct. UPS's and VFD's are very different electrical devices. Usually, UPS systems designed to supply AC to motors and drives are very large (rotary UPS) or alternatively, backup power can be provided for these large loads with generators.
Do i need to unplug my ups from surge or wall outlet if not in use?
You don't need to, but since UPS devices do draw current even when no loads are connected, you probably would want to. By the same token, UPS's have batteries which should not be allowed to fully discharge and set idle for long periods of time.
@@realparsSo is it safe to unplug during night when not in use?
Nice video Sir. Please make video on SPD, Barriers and Isolators. Difference between barrier and isolator
