Regulated power supplies
Hi Ufo,
I guess it would be clearer if they stated the specifications like this:
60Volts or 10 Amperes (whichever comes first on the particular load) and up to 600 Watts maixmum.
So:
Using resistive loads for simple examples.
6 Ohms will max out current at 10A and voltage at 60V and be at max power of 600W.
Say you have a 4 Ohm load. It will draw 10A from the PSU which will regulate at 10A and set the voltage accordingly, 40V in this case. If the load heats up and goes to 5 Ohms, the PSU will maintain that regulated 10A and automatically raise to 50V. (If you have the voltage adjustment set above 50.) In this example the 600W rating is not achieved.
Say you have a 20 Ohm load. You could set the PSU to supply anywhere 0 to 60V. Current will be determined by Ohm's Law but would never exceed 3A. If you had the current dial on the PSU set lower than 3A, say at 2A, then the voltage will be limited to 40V such that 2A is not exceeded.
PSU = power supply unit.
You have 10A max or a lesser setting and/or 60V max or a lesser setting and the PSU will regulate at which value it encounters first.
I hope that is understandable.
