Digital Three Phase Line Voltage Monitor

Wagner

wagnerPart No. DTP-3

DTP-3 offers continuous protection against voltage anomalies which can damage compressors, motors and other sensitive electrically operated devices.

Description

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 DTP-3 is automatically 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 remaining 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 displayed or cleared by the front panel buttons.
