Description
These IRK series of NEW ADD-A-paks use power
diodes and thyristors in a variety of circuit configu-
rations. The semiconductor chips are electrically
isolated from the base plate, allowing common
heatsinks and compact assemblies to be built.
They can be interconnected to form single phase or
three phase bridges or AC controllers. These
modules are intended for general purpose high
voltage applications such as high voltage regulated
power supplies, lighting circuits, and temperature
and motor speed control circuits.
