DESCRIPTION
This new VSK series of MAGN-A-PAK modules uses high
voltage power thyristor/thyristor and thyristor/diode in seven
basic configurations. The semiconductors 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
or as AC-switches when modules are connected in
anti-parallel mode. These modules are intended for general
purpose applications such as battery chargers, welders,
motor drives, UPS, etc.
