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 single phase.

Carl E. Holmes Company
High Voltage SCR Controlled Power Supply, P/N 18278PS Power Rating: 350 KW. Input: 480 VAC, 3 PH, 60 Hz Output: 0 to 5000 VDC, 70 Amps max Ripple: 2 % approximately at maximum rated voltage Configuration: 12 pulse externally SCR controlled rectifier system Protection Devices: Input contactors Overload relay shutoff Input surge suppressor Thermal switches Output current limiting resistor (made with 5 Ohm Kanthal heating element) Emergency power shutoff Cooling: Each 6 pulse rectifier assembly is cooled by three 10” fans Interface: 4/20 ma converter interface for output voltage and output current to SCR controller. Enclosure: The overall dimension of the unit is (78”H x 38”W x 53”D). It is comprised of two separate enclosures each with dimensions of (78” H x 38” W x 26” D) which are integrated together to form a single enclosure. Each half enclosure has one 6 pulse transformer and one 6 pulse high voltage rectifier. Weight: Approx. 5000 lbs. SCR Controller: The 12 pulse SCR controller is supplied by the customer. We were responsible for the 12 pulses Transformer and 12 pulses Rectifier section. Portability: Unit can be lifted up with a fork lift. It can also be moved around with a 5000 lb pallet jack. Transformer: Two 200 KVA transformers are used to step 480 VAC to 3750 VAC each in a 12 pulse configuration Rectifiers: Two 6 pulse rectifier assemblies capable for 5000 VDC and 60 Amps output were used. The high voltage rectifier assemblies are isolated and protected in a fiberglass plenum within the enclosure. Blocking Diode: Each diode of the 6 pulse rectifier consists of 10 diodes in series to offer a blocking voltage of 12000 V (PIV)
