DESCRIPTION

These series of T-modules are intended for general purpose

applications such as battery chargers, welders and plating

equipment, regulated power supplies and temperature and

speed control circuits. The semiconductors are electrically

isolated from the metal base, allowing common heatsinks

and compact assemblies to be built.
