Field-adjusting parameters via a push of a button, ICM Controls’ ICM492 digital line voltage monitor shields single-phase equipment against low and high voltage conditions and rapid short-cycling. The instrument continuously checks incoming line voltage for faults, displays rms voltage on a backlit digital display, and offers adjustable over and under voltage settings. The device includes an adjustable anti-short cycle time delay, control mode, universal line voltage input, universal line control voltage input, and SPDT relay output. The response time on the fault condition can also be fine-tuned.
