The ICM492 digital line voltage monitor protects single-phase equipment against low- and high-voltage conditions and rapid short cycling. It monitors and displays real-time voltage and has the ability to field-adjust parameters at the push of a button to meet the specific needs of the user. With the easy-view backlit digital display, users can continuously monitor the ICM492’s incoming line and root means square voltage. ICM333 head pressure control operates as a pressure or temperature-sensitive motor fan speed control, regulating head pressure by varying the amount of airflow through the condenser. It helps prevent evaporator freeze-ups, liquid-slugged compressors, low-pressure cutouts, and overshoots common with on-off and pressure-switch controls. By allowing for dual probes, the control can be used for a wide range of systems, including single-fan, multicoil systems.
