Description:
Powerex Three-Phase Diode
Bridge Modules are designed for
use in applications requiring rectifi-
cation of three-phase AC lines into
DC voltage. Each module consists
of six diodes and the interconnect
required to form a complete three-
phase bridge circuit. Each diode is
electrically insulated from the
mounting baseplate for easy
mounting on a common heatsink
with other components.
Features:
Isolated Mounting
Metal Baseplate
Low Thermal Impedance
Applications:
Motor Control
Inverters
UPS
