At last someone who gives clear detailed instructions on how to use a PSU. Ive watched loads of videos but your is by far the best for a total female beginner. THANKYOU
For the last few hours, I've been trying to bring myself up to speed on using my entry level benchtop power supply. Your video is the clearest and straight forward so far. Thank you very much.
Thank you so much for this video!! I just bought a cheap power supply and i was just getting ready to send it back because i didn't think it was working. You explained everything so well!! I have been watching videos for the past hour and they all had me confused. Your video got me back on track. Thx again!! Take care!! Aaron
Thanks man! I got myself a power supply about a year ago similiar to the one on the right except mine's Evetek and it doesn't show wattage, but to this day I had been rocking my brain in figuring out how to display the change in current output on the machine, so I gave up on it supplying current and just focused on voltage. Appreciate the help!
I have a unit similar to the one on the right. "Nice" is the brand on it. One of the many sellers warns you to ONLY adjust the current limit (by shorting the leads) when the voltage is set to 5 volts or less! That isn't mentioned anywhere in the manual that came with the unit.
I knew I could set them but I never really knew how they worked in concert with eachother, also that’s crazy bro you just found that out with all that you do @sreetips lol :)
I found your video via Perplexity 8-) which is cool to have a human explaining. Thanks for showing the setting of ceilings values, and charging that li-on battery which I was trying to do to revive a death dewalt 20V pack.
i bought a power supply because i plan on doing some electroplating, and this is the best ive seen so far I know this video is 2 years old and you've probably since moved on or perhaps have already done so but a best practices and safety video would be nice for those of us who are a bit gunshy
Nice video. A couple of features to look for that don't necessarily add a lot to the price are a lock button that locks your adjustments so you can't accidentally change your settings and a separate power switch to allow you power on/off to the leads after you've adjusted your settings without turning off the main power.
Thank you so much; I have a power supply and this was no where in the whole instructions and it is made by a diff manufacturer… and this works thanks thank u
I started researching how to use these because I thought the one I bought was broken! At 3:00 you answered my question! Don’t forget the rubber gloves! 🤣
Note and an assumption on my end. As far as the black one staying on longer and the white shutting off instantly my guess would be that they both are shutting off slowly the white just cuts off the display. Would both have caps they need to drain?
Very nice tutorial. I have been using the Longwei identical to the one you were demonstrating for some time, but this video actually taught me some things I did not know about the unit. Thank you.
Thanks for sharing your experience and thoughts. I am currently researching bench top power supplies. Appreciate you explaining these details and differences. Helpful video Update: Just ordered a Longwei 3010D with course & fine adjustments from Amazon 2 day delivery 😎😄
I know it's an old video, but it helped me get my head around how to use this. I'm using kind of the same purpose as you with lithium cells. Mine have dropped to 0v so bumping them. See if they are any use so putting them to 3.6v and testing the resistance. I'm not very good with electronics so doing this in the garage. I have built 10s4p packs and 12s3p for my electric skateboard but with new cells. I managed to get hold of couple hundred or so recycled cells see if i ca do something with them. Thanks for the quick video
Thanks for the video. I just recently purchased the Longwei that you have. I was mostly conserned that I might damage it by miss using it. Thanks again for a clear explanation on the proper use.
Thanks for this. I just bought the Kungber 30V 10A unit which I like. This said the instructions that come with the unit are okay, but only okay. I really needed to see someone step through the basic possible configurations of the device, with constant current and constant voltage, and the automatic cross over between the two, in order to understand how the controls work and what the displays mean. The Kungber seems like a well made, basic tool. The wattage display is a nice bonus.
Well explain to me how to use it. I recently bought the same exact model, and I really only need it to test headlight assemblies. I'm confused on to set the voltage, and amperage. Most of the assemblies I'll be testing only need 12v, about 4 amps, 55w at the highest for bulbs. So do I set it at like 13 volts, 4-5 amps, and then it's plug and play to the assembly?
The current control is just a current limiter, that is all it does. You can leave it on maximum for most things. Its useful if you are testing something that is delicate, ie a new circuit you are testing and you want to limit the power for the trial run to make sure nothing overheats gets damaged.
It has been quite a few decades since I diddled with electronics, at least in "bench mode." I've just gotten this new Kungber and am still trying to muster the courage to actually connect it to my breadboard circuit. It is just ~so~ counter-intuitive to me to see my selected voltage in the display and SHORT THE OUTPUT! But I'm doing it...ever so gingerly. I think I am going to pretend for a while that the current controls just do not exist (like in my old-timer experience). I really do not like to work with power without feeling absolutely in control, without everything being completely intuitive. OK, I'll set the current, but only change it with great deliberation. I guess I feel like I have to, because I don't see the easily accessible fuse on the front panel, which used to put the brakes on my current. And, of course, I can see that this is really so much better, because a one-amp fuse my have limited the fire hazard in the past but didn't do much for protecting the low-power ICs and other components that we mostly work with now. (If I had been on the design team for this product, I would have insisted on a button that said "Adjust Current" and shorted the output internally without me doing such a wretched thing myself. IMO, kinda bad to initiate total newbies into any kind of electrical work without supporting their wise instinct not to connect + straight to -.)
Great info. The manual was more than lacking information. Especially on set up. Is there a way to set s fixed output for both Voltage and Current? Let's say I want to supply a constant 36V at 8A, could this be achieved?
I have a Kungber power supply like yours and I have been using it to drive a small 12V stepper motor. Today, I went to go use it and it is showing nothing but zeros. Zero voltage. Zero current. Turning the knobs changes nothing. Any ideas on how to fix this? Is my power supply junk?
Your black psu do turn off instantly, but it takes a while to discharge the output capacitors. If you connect a load and turn it off you will see that it shuts down almost instantly...
Great video. The earth terminal. Are both power supplies isolated from earth . If you wish to get a positive and negative voltage can you connect the positive of one supply with the negative of the other
That Kungber has two models, 5A and 10A. I wonder if the 5A can be modified to output 10A also. I bet they have internally the same components (for production efficiency by the manufacturer). It could be just one resistor affecting the max current limit.
i have one that has a special knob instead of a potentiometer style thing, and when you press on it, you can change which digit you want to change, so it works as a coarse and a fine knob at the same time.
Not one place I looked, none of any of the half-a-bakers-dozen manuals I've looked through this past week, sniping best prices on "best of affordable breed" bench power supplies informed me 'precisely' with no jumper between Negative - Black and Ground - Green, do these produce -15V to 0 to +15V maximum for the 30V models? also, since I purchased two of the same type last night to be safe. Do I jumper the my circuit's Negative power supply's Red - + - Positive to the Ground feed on my breadboard, then the Black - - - Negative on my Positive power supply jumpered here as well?, leaving the negative's Negative lead as negative in my circuit? and vice verse Red on my Positive supply . I will have twenty Amps total capacity, correct? if yes, I bought the second one erroneously last night when I bought my first "Official" bench power supply. Way back when I was doing this before, "Watching myself insert an irreplaceable ROM that is not backed-up since that part of the course is next semester, well, teaching backing-up ROMs not included ever, Inserting it Backwards in the socket, realizing just in time for the thing to get hit "just a little bit See? it works after that" and seeing as how shorting capacitors smells like ambrosia, what was I gonna ask? "Do these Negative-Ground-Positive bench power supplies hide the answer to this question on purpose? 30 Volts 10 Amps Can I trust their Ground terminal to be Earth Ground, NOT Neutral, and my circuits will get Zero to Plus&Minus-15V on the 30V models?
This was probably the best explanation I’ve seen so far on bench power supplies. I’m about to start top balancing my new 280ah cells. Still a little confused on whether these units eventually shut off when they reach the max cell voltage. 3.65. Or if you need to monitor it.
of course not dude they're bench supplies how are you going to use it to test stuff if you want it to run all night you want it you run all night. you're going to want to get some bms chips, they're available for single cells, or packs in different configurations of S and P. the bms will shut off the current after the battery is charged. they're also cheap, like i got a whole board of single cell ones like 10 chips for 5$, they just have tabs to solder on input and output wires.
Great video thanks for sharing, it’s possible the kungber has residual charge in it capacitor/s and takes time to power down, be interesting to switch it off under load and see if it powers down faster. Thanks again for a very informative upload.👍🏽
If you want precise outputs of voltage & current use the power supply in tandem with digital multimeters & adjust voltage & current to your requirements. You can buy two DMM for $50 & now you have better metering for you bench power supply.
From someone who is familiar with these, I have seen on AliExpress they have different prefixes, some are NPS, DPS, WPS and many more. I'm thinking about getting one for electronic repairs, mostly phone and laptop boards. What is the difference between the NPS306W and DPS305U power supplies?
New subscriber trying to learn as much as I can before my Lithium iron cells arrive. You explained this perfectly not everyone watching understands what each piece of hardware being used is for.
Hi, was wondering if you could help. On my tire lathe I have a 1/10 th scale remote car dc motor and I have the kungber power supply from this video. When using it the motor is easy to stall and makes it unuseable because of this. I confirmed with a battery for a temp power supply and the motor wont stall when using the battery. Its like as soon as I load the motor up it stall with the kungber. Any ideas? What am i doing wrong or is it a bum unit or am I a bum unit lol. Thanks
Hello. Late to the game, but I am a learner. An amplifier board needs +/- VDC. How does a bench PSU supply this? Are there + and - leads/outputs? Thanks!
Do you think one is more accurate than the other? I need to buy one soon. Very well explained. I watched a couple other videos before yours and still had no idea how to adjust it. All I need it for is to parallel top balance 8 LiFePO4 280 ah cells.
This is the video i needed! I am currently trying to charge a 12 v motorcycle battery. I am limiting the volts at 12v and the amps at the max battery amp input at 2.6 amps. I am curious why when I connect the power supply to the battery it only draws 0.008 amps.
It maintains cv and will not switch over to cc to supply the battery with a decent amount of current to charge it quickly. Its a lead acid battery so i’m not eager to test my hypotheses on it. If i bump the voltage ceiling up i do notice it will take an appropriate amount of current but i don’t want to explode a battery in my garage.
12V lead acid batteries typically charge at 14.4 volts (that's what a cat alternator generates). Check the datasheet for your battery's recommended charge voltage.
I'm trying to use one of these to electroplate. I set it to 3.0V, then short the terminals and set it to 0.70A. But then when I connect the object to the -ve and the zinc anodes to the +ve, it goes into constant current mode and only shows 0.3V & 0.7A. I can't adjust the voltage. I'm so confused.
can these not be hooked directly to a motor? I connected it to a 775 dc motor and it wouldn't turn it. it did turn a smaller one though. When I try to turn the bigger one the voltage drops super low
I have a few devices that the charging port has broken and was wondering if I can simply use an alternative way to charge my lithium batteries from these devices mostly flashlights? Would these power sources be able to charge lithium batteries?
I have an odd task that eventually brought me to this video. I'm trying to shore power an 18650 powered device. I have seen a couple "dummy" batteries that have a wire coming from segregated terminals in a printed housing to mimick an 18650. Could a device like this safely shore power my 18650 gimbal? Thanks for any input!
I've power 18650's with these for sure. Just make sure you know what chemistry you are using, and set the max volts for the voltage that corresponds to a fully charged battery, and make sure to set max amps to an amount that is safe. If you are just powering the device directly make sure to figure out its voltage and power needs and set those in the power supply, but you could definitely use this.
@@TheWilltoBuild thanks for the help sir, this gives me the confidence to try my idea in the future, hopefully without any magic smoke. also, i asume for safety sake, best to use one power supply per battery? I also assume that depends on how the power is configured in the device?
thank you for that, my PSU sparks when I connect the leads at any voltage above zero to adjust the Constant Current, could it be that on some units you need to do that with the dials turned down to zero only
Awsome vidéo, just a question, in a power outage or losing power for a few minute wich happen all the time where I m from, will this unit will go back to is pre set setting?
At last someone who gives clear detailed instructions on how to use a PSU. Ive watched loads of videos but your is by far the best for a total female beginner. THANKYOU
and a male apparently. Thank you!!
Thank you for not having a 12 minute intro.
For the last few hours, I've been trying to bring myself up to speed on using my entry level benchtop power supply. Your video is the clearest and straight forward so far. Thank you very much.
Glad this helped. I went through the same experience.
Agree.😎
Definitely the best one I've seen so far
Mine has been sitting in the box until finding this video... It's like getting a birthday present all over again!
@@TheWilltoBuild if I set mine on 14V and connect it to a battery it automatically jumps into CC 🤦🏻♂️ HOW does it stay in CV?
The Kungber on the right is the exact model I just bought! The instruction manual looks like Google translate was drunk, so I appreciate the info.
Thank you so much for this video!! I just bought a cheap power supply and i was just getting ready to send it back because i didn't think it was working. You explained everything so well!!

I saw videos regarding this power supply. I must say that this is one the BEST video and awesome explanation. Thanks a lot. 💐
Very good tutorial! I cracked up when you perfectly placed the ad segue when the camera mount moved. I like your videos!
Finally ! A clear explanation on how to use these things properly and safely .... thanks brother ! 😊
Very helpful video! This is really what people will need if it's the first time they bought themselves a bench power supply
Finally! An explanation on CC/CV power supplies that I can understand. Thanks
Glad it was helpful.
Super helpful. I recently acquired a real "Shenzhen Special" with terrible operating instructions. This was so much clearer!
Glad it was helpful!
Great video man, it took me 5 or 6 trys with other clips but as soon as u spoke I knew exactly how smart u are and how articulate.😊
Thank you for a great explanation on setting the power supply up to read voltage and current.

This is what I spent all day looking for. Thank you and nice job
I had challenge setting the current, thanks for the current adjusting explaination
I'm with sreetips on this one man. Great job. thank you.
I started researching how to use these because I thought the one I bought was broken! At 3:00 you answered my question! Don’t forget the rubber gloves! 🤣
You definitely explained how to set up the Kunberg better than the instructions did. Wish I had watched your video first.
Helpful immensely. I also read your safety message in comments too that is excellent too. Cheers hey!
Amazing, thank you. As someone that knows nothing about this, this made it very easy to understand.
Note and an assumption on my end. As far as the black one staying on longer and the white shutting off instantly my guess would be that they both are shutting off slowly the white just cuts off the display. Would both have caps they need to drain?
Thank you for clearing this up for me. It was a complete mistory until I watched your video.

Update: Just ordered a Longwei 3010D with course & fine adjustments from Amazon 2 day delivery 😎😄
Thanks, you have a easy way of explaining things and this helped me understand how to set the CC mode.
Very helpful, as a beginner I appreciate this very much.
I like the ad break right when you drop your camera. Very suspenseful.

can this supply be used to.isolate a short or does it got short protection
In order to adjust the current you have to short the leads. So I imagine you could use it to isolate a short.
Could I use this to charge a gen 2 prius module instead of a hobby charger?
This cleared up a lot for me. Thanks!
What are the settings to connect a car battery for a garage car stereo system?? Thank you
I have a few devices that the charging port has broken and was wondering if I can simply use an alternative way to charge my lithium batteries from these devices mostly flashlights? Would these power sources be able to charge lithium batteries?
These can definitely charge lithium batteries! but make sure you know what to voltage to charge them to.
Great video This is exactly what I needed.
I have an odd task that eventually brought me to this video. I'm trying to shore power an 18650 powered device. I have seen a couple "dummy" batteries that have a wire coming from segregated terminals in a printed housing to mimick an 18650. Could a device like this safely shore power my 18650 gimbal? Thanks for any input!
I've power 18650's with these for sure. Just make sure you know what chemistry you are using, and set the max volts for the voltage that corresponds to a fully charged battery, and make sure to set max amps to an amount that is safe. If you are just powering the device directly make sure to figure out its voltage and power needs and set those in the power supply, but you could definitely use this.
@@TheWilltoBuild thanks for the help sir, this gives me the confidence to try my idea in the future, hopefully without any magic smoke. also, i asume for safety sake, best to use one power supply per battery? I also assume that depends on how the power is configured in the device?
I just got the one on the right, but when I connect the positive and negative I get quite the spark. Is that supposed to happen?
When calculating the max amps you state you need to connect these 2. The screen does not show what you are connecting?
Thank you for video, my bench psu didn’t have detailed manual, this helped
thank you for that, my PSU sparks when I connect the leads at any voltage above zero to adjust the Constant Current, could it be that on some units you need to do that with the dials turned down to zero only
For that kind of Battery what is the right amper when you charge it?
Awsome vidéo, just a question, in a power outage or losing power for a few minute wich happen all the time where I m from, will this unit will go back to is pre set setting?
But What Will hapen if You short them at maxium voltage Will The Home Breaker Pop?
Can you desulfate a car battery with this ... except it'll take a long time ?
Would these power supplies push a 300watt subwoofer and amp?
