ICM491 Single Phase Line Monitor

The ICM491 is a very low cost, highly accurate, rugged, single-phase voltage monitor designed to protect single-phase devices from the following abnormalities…

Designed in a small, easy-to-mount case, the ICM491 continuously monitors incoming line voltage for errors. When line power is appropriate, the ICM491 closes a set of N.O. contacts and lights a green LED. When incoming power is outside of user selected parameters, the N.C. contacts will close and a red LED will illuminate, indicating current fault conditions. This unit also interrogates the line during fault conditions to reduce nuisance trips from transients or compressor start ups.

Features:

  • Protects Against:
    • Over/under voltage
    • Rapid short-cycling
    • Power interruptions
  • Heavy Duty SPDT Relay Output:
    • 5 amp relay output to operate control circuitry or contactor
  • 5-Second Fault Interrogation Period:
    • Unit trips if power is abnormal for 66% of interrogation time
  • Anti-Short Cycle (ASC) Time Delay:
    • Delay on Break (.1 to 10 minutes)
  • LED Indicators:
    • Green LED On: Power is valid, relay energized
    • Red LED Rapid Flash: Unit currently detects high/low voltage situation
    • Red LED Blinking: Power is currently valid; unit is waiting for end of ASC delay
