Product
Digital Three Phase Line Voltage Monitor
Purpose
The DiversiTech Digital Three Phase Line Voltage Monitor oers continuous
protection against voltage anomalies which can damage compressors,
motors and other sensitive electrically operated devices.
Features
• 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
depende
• 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) xed 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.
• 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.
