Read More About 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.
The Variable Transformer Controlled units are more expensive, but the ripple on the output remains unchanged at 5% levels as output is lowered from the maximum. Most variable DC power supplies are custom built. Units can be an open frame or enclosed inside an enclosure. Input/output protections can be provided per customer requirements. Output voltage and current meters are provided per customer requirements. The units can be PLC controlled or Manual Potentiometer Controlled.
