High Voltage SCR Controlled Power Supply, 0 to 2500 VDC, 90 A Output

Product Overview

High voltage SCR controlled power supplies consist of a SCR controller on the 480 VAC three phase input power lines. The three phase power transformer is used to step up the secondary voltage so that after rectification the desired high voltage DC output is achieved. Each diode in the rectifier circuit consists of multiple diodes in series to increase the overall peak inverse voltage (PIV) of the diodes. The high voltage rectifier section is enclosed inside a fiber glass plenum to offer high voltage protection. Circuit breakers, fuses, voltmeters and ammeters can be added per customer requirements.
