Description

A dual mode firning circuit driven from a remote potentiometer, voltage or current signal used on three phase applications.

The firing circuit is designed to drive a wide range of thyristor
types in different configurations but is commonly used to trigger
three thyristor pairs in 3-phase thyristor control assembly
applications.

Each thyristor is individually driven by high-frequency
voltage pulses, capable of driving high current devices.

• Output status LED
• Over current latching
• Phase rotation reversal
• Adjustable soft start
• Current limit input
