Description:
OUTLINE DRAWING
Powerex Dual SCR 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.
TM
POW-R-BLOK has been tested and
recognized by the Underwriters
Laboratories.
