Hi, I want to use 3 different amplifier modules which have integrated power supply in one enclosure.should I connect them in series or parallel. much appreciated
How about total current of series connected power supply? lets say 12V 10A combined with 15V 5A, total voltage is 27V, but how much current can be served?
I would like to know what happens if sources have different voltage and amperage. That is, if connected in series, voltage because their sum, but what haplens to amperage ? And if in parallel, amperage becomes their sum, but what happens to voltage ?
Floating... So suppose I have two isolated channels channels 0-30V each I connect + of one channel to - of the other, and using this have a reference I can have a +/- 30V power supply. If I want to see ripple of the positive rail using an oscope, can I connect the common of the probe (ground) to the above connection? If not, what would happen?
Strange that no experiments were shown for parallel connection: real experiments shows that in parallel from two sources you will get not 2 but 1.5 times more amperes. 10a + 10a will give 15a in a best case, over this value one of sources will break and consequently second also.

5A

In series the max current is generally unaffected and in parallel the max voltage is unaffected.
Where can I find the maximum voltage to ground rating of a power supply I just bought?
Should written on the back or on the fuse cover

If you connected your scope to any “ground” that is mains earth referenced, which your scope surely is, then you would blow up said scope! 🔥⚡️😢
nice video. straight to the point.
Thank you!
⭐⭐⭐⭐⭐👍
A lot of nonsence, or incomplete informations ...
Sorry to hear you feel that way: could you explain what you think is "nonsense" or "incomplete"? Thanks!
The best explanation ever
Can i use a 5 voltage dc charger and 9 voltage charger in series
Probably not since since I'm guessing they are both referenced to ground. To combine voltage sources, they have to be floating.

That would be a function of the supplies. I've done experiments where I got 40 amps out of 4 10 amp channels in parallel
