, this is great. most manufacturers of ALL class d and class T amps usually provide power supplies that are ( HALF ) of what the amp needs or amp " Board "!!!!!!! SMSL and Micca are the only companies that I have found that provide the proper power supplies.
Thank you so much for this explanation adding the 22 to 100 watts also helped a ton I can finally have some faith In my project now that I got a basic understanding of this
Wow man you couldn't have explained that better for me especially!! I have a way of making something very simple complicated. Great video thank you very much!! Aaron
how are you gonna know where actually live is on european 220v plug??? You can plug it upside down into the socket. Moreover, usually nobody gives a f*** connecting live and neutral to the socket
I wish you went a bit further with this and hooked up the audio. I'm curious if that switching PSU had any noise issues that you could hear in the signal once you had the speakers hooked up. I'm thinking about using one of those PSU's on a vacuum tube mic preamp I'm building. The guy who designed the preamp actually designed it with a switching PSU in mind, and he has some high frequency filtering in the design, but I think he intended the PSU to be external. I'm going to be racking up TWO of his PCBs into a 2U rack box with the PSU in the rack box.
That's highly dependent based on what you're hooking it up to. I'm not sure that anyone could really answer that besides the designer of the tube preamp. It's a very clean power supply. With what I use it for, I don't get noise. What I haven't done extensive testing.
I was looking at this supply as an option for a bipolar power supply to power a few projects that require from - & + 5V to - & + 12V as well as ground. Why are you using the -V output for ground as opposed to the ground terminal for ground? If you're getting 24V on your multimeter when measuring the output voltage with the black test lead connected to -V and the red test lead connected to +V, what do you get if you move your black test lead to the ground terminal?
the electrical dangers of the mains side voltage should be made much more explicit, from the very start of the video. errors with mains voltage can be fatal!
I've watched several videos on how to hook-up a power supply like this. In one video, they had a jumper between the Ground and V-. It was never explained why this was done. Could you explain why such a jumper might be used? Thanks.
1.what happens if the cause our mains are 240v and the power supply only rated at 220v eill it be ok to our country? 2. What is the +-15% means on the voltage input, I researched it I think its tolerance, what does it mean?
Thanks for the video - very helpful! One question: specs of RS-100-24 say that output voltage range is 22.8 to 26.4V in the video you could go as low as 22.2V - is the spec wrong and in fact there is more adjustment range? cheers!
Hi there. Thanks for the video. I have a 12v DC 8 amp water pump. I am planning to use a timer which will switch on and off every 5 or 10 minutes, running for a minute or so. Can use meanwell LRS-100-12 power supply unit to hook it up to a timer switch. My plan: Timer-power supply unit-water pump. Is this the correct set up. Please. Thanks in advance
Man what an amazingly clear description...pure Brilliance in delivery of information. Hats off to you for this . However what was the plug that you used on this ? Is it a 3 pin plug or the normal 2pin plug that goes into the mains ?
Nice. How can I connect SMPS to electronic semiconductor refregerator radiator cooling equipment??? Please show me a step by step like whay you just did. Thank you.
I have a power supply, model RSP500-5 and when I apply power supply (220VAC), the led lights up and goes out and there is no 5VCC output, what could be happening?
Lets say I want to connect a few of those together for more amps how would you switch them on.I did see your other video with the car radio and the light switch.
Ive got a 3d printer w 24v meanwell power supply. Do you think I can add a XT60 pigtail to power a 650w 15a LiPo charger to it while the printer is on stand by mode? Tya for your reply.
Hello. . . Could someone here please help me figure out what appropriate power converter would i need to push a 1000 watt 4 channel amp into 2 X 650 watt speakers? Thanks in advance! Putting all these speakers to use again has been a blast;) THANKS FOR THE VIDEOS!
Ha! Here, black is neutral, and we don't have white. Blue, brown and green with a yellow stripe (for colour blind people). Anyway, the standards may be different where you are. (Australia here, with 240v mains). Be safe and double check those colours.
I have a car stereo powered in my room. With 12V 5Amp works good hits pretty good also.. But I ran into this very power supply yesterday an I'm jw if I could hook the power supply into the car stereo and add 100w or if ittl actually work the way I expect it to or burn the stereo up so I need some opinions
Or I could wire it separate from stereo and run the amp and sub on the power supply and just run the stereo on what it's already on Before this supply box I had to use a 12v car's battery charger to power the amp an subs so I'll be hopeful lol
I’m building the oscillator from Moritz Klein’s channel and I need to power an op-amp IC, alongside regular Vcc to Gnd elements. I have an Arduino Uno and I’ve been using a voltage inverter circuit next to the op-amp. I got this power supply in order to free up the breadboard space, and to ideally remove the Arduino from the picture. I will be dialing down the voltage as low as possible, but should I still be using a separate device for the ground, maybe the Arduino’s ground? I believe the negative voltage will be isolated from the ground in the circuit, as it should only be used for the op-amp in this project. but if possible, I’d like to remove the Arduino and use the ground (i.e. into the cord) on the power supply.
You're Welcome. I am glad it was useful to you! I should have a new tutorial out tomorrow or the next day showing how to make carbon fiber LED lit speakers, if you are interested. I thought it was a pretty cool project myself. Now if I can just get my editing program to agree with me ;)
Do these power supplies come already set-up with the specified output rating? ...Or is it better to 'always' check it with the multimeter? ... Good video. Thanks!
Hi, I have a question on the Mean Well. I want to use the DC volts for my H O scale trains, and LED lights for my buildings. Do you know if I need any other items? such as any PC boards? The purpose of buying the Mean Well was to add more DC volts, any thoughts on what I need would be greatly appreciated thanks,Ken
Could you measure if the negative lead coming out is earth referenced? I believe that's how you say that excuse my eng I'm Dutch and just starting in electronics
@@mehulsingh2403 Connected in serial, they will provide higher voltage. Connected parrallel, you can draw higher Amps. Yet be aware. That is out of specs and you void warranty. They are not extremely expensive, yet not cheap eighter. Good value for the money they are. Another thing is that in worst case, you can start a fire that way. Just pick a higher rated PSU from MeanWell. They are cheap enough, and they have tons of different models. All equally good. Just avoid knockoff copies from china.
If i understand correct, it is regulated because you regulate it yourself for a fixed load ?, so it is not really regulated ?, i dont know if i wanto buy this thing, since i dont have always the same load.
Here's the definition from wikipedia: "A regulated power supply is an embedded circuit; it converts unregulated AC into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits." Basically, anytime you work with sensitive electronics you want to get the cleanest source possible. This is the best way to ensure that. Also you can regulate it to whatever load you need within it's range. I hope this helps.
I'm a noob at this. Just bought a S-250-12 model psu and going to wire it up... But(!) we don't have many grounded sockets here (Norway) and the ones we have, you can put the plug in both ways(I.e. switch the N and L).. As stated, i'm a noob at this.... Any takers?
hi,yes you can always turn L & N around because its AC alternating current,AC current changes the polarity or +/- every 1 second 50 times/cycles or 50 hz,so polarity al the time changing anyway,only DC you have to always check for polarity,with AC only in your fusebox you can not change the L & N!No worries!cheers
The metal box, is actually the enclosure. Some of these power supplies actually have a plastic guard that goes over the screws, this one does not. However, you can put them in a different enclosure if you want. It would be pretty simple to stick them in say a plastic ammo box with an iec socket on the outside. That would give you more protection if you wanted. Or go to your local hardware store and see what you would fit one.
Hi, does it realy matters that L & N is exact correct ?, here in Holland you can place the power-cord in the wall 2 ways, so it should not matter, you can reverse it ? greetings
Hi, i just called the shop, they say it dont matters because you can reverse the powerplug, earth is needed for sure. At least here in E.U. ( Holland ) + if you look L & N is inverted 50Hz sinewave of eachother.
hallo,dat maakt niets uit,je kan altijd de L en N omdraaien aan de stekker of stopcontact omdat het ac current is!AC is alternating current dus je kan altijd de + en - omdraaien!dat doet AC automaties met 50 cycles of hz per seconden,alleen niet in je stoppenkast kan je de + en - omdraaien!cheers
Арxитектор Вселенной well it plugs into your wall socket. In the US that's 120 volts. And it'll pull as many amps as it needs or until it flips your circuit breaker (ie you overloaded your breaker).
Арxитектор Вселенной It'll pull a lot less than 13 AC amps. Check out this site. www.batterystuff.com/kb/tools/ac-to-dc-amperage-conversion-run-through-an-inverter.html
Hi, I have a problem with this matter which would be very appreciative if someone can elaborate for me. I want to make a diy speaker by buying a full range speaker, amp board 1x50w and lithium battery. Now, as you would see from above, the last item is the lithium battery, yes I want to use it without a "power supply" Question: Can I create this theory diy speaker I want without the power supply? I had bought previously a bluetooth speaker and changed the speaker by de-soldering the negative and positive wires and re-attach it and worked flawlessly, only downside, the amp was weak, not pushing the woofer to its full potential. I checked that by trying it out with my own Griffin amp and it blows my mind how good a 15 gbp woofer can sound, only sad thing is, I bought a mid woofer, not the full range. Anyway, thanks in advance for help if any ...
I'm not sure with the cabel input... You use ground line ? It is not secure... It is so danger... I think, it must use L and N for power input with 2 cable
Hooked up my power supply on my LRS-150-12 multimeter says 120 volts going in and then there is zero coming out and the green light won’t come on. I think I got a junk unit ….
Great... I was actually looking for this. Now... There is no difference between neutral and live. It is AC. And it does not matter how you plug it into the wall. And you can find cords, were there is no connection for "neutral" and "live". The ground/earth is the only one you need to watch out for. Regarding getting a shock. Then you will not get any, if you only touch one. If both or anything else, then you will get a shock.
Dugagjin Dervishaj you've misunderstood me. At this point I think you're best off doing some googling. Read about ac-dc converters and dc- AC converters, switching power supplies and linear power supplies. Ask again once you've figured that out.
For the love of god, please put properly crimped connectors on those mains wires. Bare copper wires should never be attached to those terminals because of 'work hardening' (micro-fractures).
Nice video! I just have a question. Have you noticed any background noise caused by the power supply? I’m no electrician but I’ve read some posts about smps supplies leaking noise from the switching into the audible frequency band. I’m thinking of building a dual mono amp with two of these in it.
That is a good question. I have not noticed that at all. However, I run these on bass shakers that only get 80hz and below signal and only comes on when bass hits. SO I probably would not notice it.
123Toid aah, ok. I’ll continue my reading and I won’t let all audiophiles get to me with all the talk about toroidal being the only way to get good quality sound. 😉 smps are just so much simpler and more efficient!
If you have to make the statement that the cord should not be plugged in while cutting the end off; this how to video is beyond the capability of the viewer and therefore shouldn't be doing it...

Single phase 120, unless they’re standing in a tub of water with wet hands, not likely fatal by a long-shot.

Hey bro quick questions can I use only two wire to power the power supply?
Because here in Philippines we only use 2 wire on one cable?
Excellent video...great explaining
Just for safety reasons, shouldn't the amplifier board have a chassis ground connection?

Hello there . I would like to know whats the best input current needed for similar device =24v 20a output= to fully function to 100% ???
VxA=W so you need a 480 watt power supply. Over you do need to take him to the efficiency of the board amp, so 550 watt power supply would be better
i dont get it dows this device that im talking about need 2230v and how many amps to fully function ???

And you can find cords, were there is no connection for "neutral" and "live". The ground/earth is the only one you need to watch out for. Regarding getting a shock. Then you will not get any, if you only touch one. If both or anything else, then you will get a shock.
You will never see a real 50x50 Rms from a 24 volt supply with only 4.5 amps. A may pop amplifier. It may pop at anytime.
can you use this as AC to DC converter?
Dugagjin Dervishaj that's exactly what it does. It converts AC to DC current

im completely new new in to electricity fields my friend. .
and a question what about from DC to AC ?
does this part helps?
No, this won't convert DC to AC. Why do you want to do that?
+Jefferson Allan now to which one should i believe?
Dugagjin Dervishaj you've misunderstood me. At this point I think you're best off doing some googling. Read about ac-dc converters and dc- AC converters, switching power supplies and linear power supplies. Ask again once you've figured that out.
For the love of god, please put properly crimped connectors on those mains wires. Bare copper wires should never be attached to those terminals because of 'work hardening' (micro-fractures).
"L" stands for "Line".
Nice video! I just have a question. Have you noticed any background noise caused by the power supply? I’m no electrician but I’ve read some posts about smps supplies leaking noise from the switching into the audible frequency band. I’m thinking of building a dual mono amp with two of these in it.
That is a good question. I have not noticed that at all. However, I run these on bass shakers that only get 80hz and below signal and only comes on when bass hits. SO I probably would not notice it.
123Toid aah, ok. I’ll continue my reading and I won’t let all audiophiles get to me with all the talk about toroidal being the only way to get good quality sound. 😉 smps are just so much simpler and more efficient!

If you have to make the statement that the cord should not be plugged in while cutting the end off; this how to video is beyond the capability of the viewer and therefore shouldn't be doing it...
So true. I also don't want to see anyone get electrocuted or trip a breaker. But I couldn't agree more.
quangluu96 lol
Sadly the statement has to be made because it has happened before
@@QueueTeePies Mains voltage isn't high voltage.
“L” is for line!!!
You are regulating the voltage.
Yes I am.
