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
