Description
The ICM 450A PLUS+ is a rugged, USA-made, programmable 3-phase line voltage monitor designed to safeguard motors from premature failure due to voltage irregularities. With a bright backlit LCD and intuitive interface, you can easily configure and monitor system conditions—even in low-light environments.
Features:
- Monitors for high/low voltage, phase unbalance, phase loss, and phase reversal, ensuring early detection and prevention
- Equipped with a real-time clock to stamp fault events with date and time for streamlined diagnostics
- Built-in Modbus RS-485 communications enables seamless integration with building management systems and remote supervision
- Customize delay-on-break, fault thresholds, retry attempts, language (English/Spanish), and control modes to fit diverse applications
- Factory-calibrated, displays simultaneous true RMS 3-phase voltages, supports fault memory recall, and features LED indicators and 1/4″ quick-connect terminals for safer, faster setup
- Accepts 190–600 VAC, with optional load-side monitoring and control voltage support from 18–240 VAC
- Operates between –40°F to 149°F (–40°C to 65°C), stores up to 185°F, and mounts easily with surface screws. Compact size and lightweight design simplify installation in tight panels
- Perfect drop-in upgrade for older units like the ICM450, ICM455, and equivalents from several brands—including Copeland, Mars, SSAC, Wagner—simplifying stock and upgrades
