Offers continuous protection against voltage anomalies which can damage compressors, motors and other sensitive electrically operated devices.

Diversitech Digital Motor Protector, 3-Phase, 160 to 600 VAC, 19 to 277 VAC, 0 to 720 s Delay, 0.1 to 20 s Response, Import

• Protects from loss of phase, phase reversal, voltage imbalance, low voltage, high voltage
• Three independent voltmeters read both line and contactor load (backside) voltages
• Power for the WPC-500 is automatically derived from any active phase
• System operation is not dependent on the control voltage or a specific phase for power
• Adjustable in 1% increments between 6% and 18% of selected operating voltage, restart voltage set point (hysteresis) fixed at cutout voltage 3%
• Adjustable imbalance trip point from 2% to 25% of selected operating voltage
• Up to 25 past fault conditions are stored for later retrieval and analysis, the faults may be displayed or cleared by the front panel button
• Operating Voltage Set Point: 175 to 650 VAC digitally adjustable in one volt increments
• Phase Loss/Reversal: 100 m-sec max
