Dual SCR/Diode Isolated Module

250 Amperes / 1800 Volts

Description:

OUTLINE DRAWING

Powerex Dual SCR/Diode Modules are

designed for use in applications

requiring phase control and isolated

packaging. The modules are isolated

for easy mounting with other

components on a common heatsink.

POW-R-BLOK^TMhas been tested and

recognized by the Underwriters

Laboratories.
