Description:
Powerex Dual Diode
POW-R-BLOKTM 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 com-
mon heatsinks. POW-R-BLOKTM
has been tested and recognized
by Underwriters Laboratories
(QQQX2 Power Switching
Semiconductors).
Features:
Isolated Mounting
Glass Passivated Chips
Metal Baseplate
Low Thermal Impedance
UL Recognized
A
Applications:
Battery Supplies
AC and DC Motor Power
Supplies
