Description:
Powerex Dual Diode
POW-R-BLOK™ Modules are
designed for use in applications
requiring AC to DC rectification in
isolated packaging. The modules
are isolated for easy mounting
with other components on common heatsinks. POW-R-BLOK™
has been tested and recognized
by Underwriters Laboratories
(QQQX2 Power Switching
Semiconductors).
