ICM Controls ICM450APLUS - Programmable 3-Phase Line Voltage Monitor, RS-485 MODBUS, 190–600 VAC
ICM Controls ICM450APLUS - Programmable 3-Phase Line Voltage Monitor, RS-485 MODBUS, 190–600 VAC
ICM450A PLUS+ – Programmable 3-Phase Line Voltage Monitor, RS-485 MODBUS, 190–600 VAC
Short Description
The ICM Controls ICM450A PLUS+ is a next-gen, programmable 3-phase line voltage monitor designed to protect compressors, pumps, and motors from costly failures. It continuously watches for phase loss, phase reversal, voltage unbalance, and over/under-voltage, logs faults with a real-time clock, and provides fast setup via a backlit LCD. Universal 190–600 VAC operation, SPDT relay output, and RS-485 MODBUS connectivity make it a versatile choice for HVAC/R, industrial, and marine applications. Proudly made in the USA.
