This module is intended for on-load monitoring of thyristors for open or short circuits. It can be used with single phase or 3-phase 2 or 3-leg thyristor stacks or solid state relays controlling AC loads operating in burst fire or single cycle burst fire modes and activated by a standard logic signal (not analogue input thyristor controllers).

  • Monitors for short or open circuit devices under load
  • Suitable for single phase or 3 or 4-wire 3-phase loads
  • May be used with 2-leg or 3-leg control of a 3-phase load.
  • Suitable for monitoring on nominal 380V to 690V 3-phase supplies or 220V to 690V single phase supplies
  • Latched or non-latched alarm outputs
  • Volt free alarm contacts and LED indication
  • Requires a 24V DC Power Supply
  • For use with thyristor stacks or solid state relays controlled by a logic signal
