xPS Series -
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)
