ABOUT SCR CONTROLLED VARIABLE DC POWER SUPPLIES

Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with an SCR controller. 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 a single phase.

The SCR-controlled units are cheaper but a ripple on the output degrades 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.

All major components like transformers and rectifiers are manufactured in-house by CEHCO to achieve the highest quality standard and to ensure the best use of raw materials. This allows us the capability of custom designing units to suit customer-specific requirements and meet quick delivery schedules. Our power supply engineers are available to answer all your questions. Please contact us at 714 624-4740, or send us an email at quote@cehco.com.
