I need to build regulated power supply 0-30V 0-20 Amps. The only solution possible for minimizing the thermal loss is to use triacs on the secondary Trafo side in order to cut the sine for low voltage output and great current. (like 5V, 20A). Please

There are pots on the board in the power supply to adjust the voltages after the machine is powered up. The location of these pots are in the munual supplied with the machine
