1.1. GENERAL PRESENTATION
7300Aseries power thyristor units are used to control the electrical power of three-phase
industrial loads of all types.
The load controlled may comprise high or low temperature coefficient resistive loads, short
wave infrared elements or transformer primaries.
Current ratings vary from 16A to 160A(per phase), at line-to-line voltages of 200V to 500V.
A 7300A series thyristor unit comprises three channels, controlled by thyristors.
