Description
This new IRK serie of MAGN-A-paks modules uses high
voltage power thyristor/thyristor and thyristor/diode in
seven basic configurations. The semiconductors are
electrically isolated from the metal base, allowing com-
mon heatsinks and compact assemblies to be built. They
can be interconnected to form single phase or three
phase bridges or as AC-switches when modules are
connected in anti-parallel mode.
These modules are intended for general purpose appli-
cations such as battery chargers, welders and plating
equipment and where high voltage and high current are
required (motor drives, U.P.S., etc.).
