Dual Diode
POW-R-BLOKTM Module
600 Amperes / 1600 to 1800 Volts
Description:
Powerex Dual Diode Modules are
designed for use in applications
requiring rectification and isolated
packaging. The modules are isolated
for easy mounting with other
components on a common heatsink.
POW-R-BLOKTM has been tested and
recognized by the Underwriters
Laboratories.
