AD-UW 60 GT

Description

The three-phase voltage monitor AD-UW 60 GT monitors all three phases in the three-phase system for overvoltage, undervoltage, phase sequence and phase symmetry. If one or more faults occur, the quiescent current relay will fail. The state of the three phases and the error state is indicated by LEDs. The device is powered by the measuring voltage, therefore the wiring of a separate supply is eliminated. The switching points for overvoltage, undervoltage and switching delay can be set quickly via separate trimmers.

AD-UW 60 GT

Application

AC motors, Overhead cranes, Trolleys, Goods lifts, Conveyor belts

Specific characteristics

Setting the limits for undervoltage, overvoltage and switching delay via the front panel
Check all relevant sizes for a wide variety of purposes
Display of the phase voltages by green LEDs
Display of the relay by orange LED
No separate power supply necessary therefore less wiring effort
Relay is energized in the good range
