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).
Features:
M Isolated Mounting
M Glass Passivated Chips
M Metal Baseplate
M Low Thermal Impedance
M UL Recognized A
Applications:
M Battery Supplies
M AC and DC Motor Power
