DESCRIPTION

This new VSK series of MAGN-A-PAKsTM uses high
voltage power diodes in two basic configurations. The

PRODUCT SUMMARY

I

F(AV)

250 to 320 A

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 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.).
