The PLMU11 is a universal, three-phase line voltage monitor with a broad voltage range and full adjustability, says the manufacturer. According to the company, the octal plug-in, three-phase voltage monitor provides protection against premature equipment failure caused by voltage faults on a three-phase line because a microcomputer circuit senses under- and over-voltage, voltage imbalance, phase loss, and phase reversal. This series is available with a fixed- or knob-adjustable voltage imbalance of 2% to 10%, and a fixed or adjustable trip delay of 0.25 to 30 sec. No connection to a neutral is required, the company says.
