Bench power supply
<< < (4/4)
xavier60:
The design I used in my recent bench supply project works properly and would be safely capable of 30V 5A with tap switching and suitable heatsink.
Because of the size transformer that I chose, it safely outputs 4A from 0V to 15V and 2A from 15V to 30V by switching the 2 secondaries in parallel or series. Likely more due to the fan cooling of the transformer.
