UL E78996 approved
Description
This new IRK series of MAGN-A-paks uses high voltage
power diodes in two basic configurations. The semicon-
ductors are electrically isolated from the metal base ,
allowing common heatsinks and compact assemblies to
be built. They can be interconnected to form single
phase or three phase bridges and the single diode
module can be used in conjunction with the thyristor
modules as a freewheel diode. These modules are
intended for general purpose applications such as
battery chargers, welders and plating equipment and
where high voltage and high current are required (motor
drives, etc.).
