Description
These IRK series of NEW ADD-A-paks use power
diodes in a variety of circuit configurations. 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. These modules are intended for general
purpose high voltage applications such as battery
chargers, welders and plating equipment
