250 A to 320 A
Modules - diode, high voltage
MAGN-A-PAK
Two diodes doubler circuit,
two diodes common cathode,
two diodes common anode, single diode
DESCRIPTION / APPLICATIONS
This VS-VSK series of MAGN-A-PAKs uses high voltage
power diodes in two 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 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.).
