DESCRIPTION  
PRIMARY CHARACTERISTICS  
This 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.
