Offers continuous protection against voltage anomalies which can damage compressors, motors and other sensitive electrically operated devices.
PROTECTION: Loss of Phase, Phase Reversal, Voltage Imbalance, Low Voltage, High Voltage
DISPLAY: Large custom LCD display indicates all operating conditions at a glance. Three large sets of digits provide easy system troubleshooting. VOLTMETER: Three independent voltmeters read both line and contactor load (backside) voltages. MONITORED VOLTAGE: 160 to 600 Volts 50-60 Hz. POWER SUPPLY: Power for the WPC-500 is automa¬tically derived from any active phase. System operation is not dependent on the control voltage or a specific phase for power.
CONTROL VOLTAGE: 19-277 VAC. Anticipator load is provided for operation with 24 volt electronic and mechanical thermostats.
OPERATING VOLTAGE SET POINT: 175 to 650 VAC. Digitally adjustable in one volt increments.
VOLTAGE TRIP POINT: Adjustable in 1% increments between 6% and 18% of selected operating voltage. Restart voltage set point (hysterisis) fixed at cutout voltage + 3%.
VOLTAGE SYMMETRY: Adjustable imbalance trip point from 2% to 25% of selected operating voltage. RESPONSE TIMES:
Phase Loss/Reversal: 100 mS max.
Imbalance: Adjustable Response Timer
Over or Under Voltage: Adjustable Response Timer LOCKOUT DELAY TIMER: Fully adjustable 0 to 720 Seconds (0 to 12 minutes). Digital display shows re- maining time and user set points.
SEQUENTIAL START TIMER: 0 to 30 seconds in one second increments.
RESPONSE TIMER: 0.1 to 20 Seconds. Digital display shows remaining time and user set points.
MEMORY: Up to 25 past fault conditions are stored for later retrieval and analysis. The faults may be dis- played or cleared by the front panel buttons.

Automatic voltage monitor and control system. Continuously measures incoming line voltage, allowing detection of any voltage outside the tolerances that you set. If these limits are exceeded, the response timer begins counting. you may also set response time – a short time for a quick response or a long time to avoid nuisance tripping. If the voltage remains outside the tolerance after the time has elapsed, the DSP-1 will turn off its output relay and protect your device. While output is off, an additional delay timer activates to avoid rapid restarts.
FEATURES:
Digital voltmeter displays instantaneous line voltage. Automatic voltage tester adjusts from 90 to 300 volts; Adjustable response timer (0.1 to 10 sec.) prevents nuisance tripping;
