Variable Transformer DC Power Supplies
-
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with a Variable Transformer (also known as variac). The Variable Transformer can be adjusted manually or with a motorized control. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

Transformer Rectifier Assemblies
-
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.
