How Does a DC Power Supply Function and What Are Its Key Features?

In summary: Usually the second one is for reverse polarity.In summary, this power supply can give 3 amps of current when the resistance is 10 ohms and the voltage is set at 30 volts. The silver color terminal at the bottom is for an Earth or ground connection.

This DC power supply apparently isn't grounded, so the silver terminal on the front panel has no connection to mains ground.

So, this thread which has gone on for 25 days and 35 posts has been a bit pointless.

Hello everyone,

Yes, the power supply isn't grounded. I will post the readings tomorrow for confirmation.

I do not think this discussion was pointless. I learned many things from you and other people in this thread so it was very helpful for me and your effort was not wasted. Many thanks. Will post readings soon.

Cheers
