3. Function

3.1

Device features

The VMD423 requires a separate supply voltage U

Monitoring for undervoltage and overvoltage and underfrequency and
overfrequency in 3(N)AC systems of AC 0...500 V / 0...288 V

Monitoring of overvoltage U2 by average determination of the latest
10-minute measuring interval

Asymmetry, phase failure and phase sequence monitoring

Start-up delay, response delay and delay on release

Adjustable switching hysteresis for the voltage to be monitored

r.m.s. value measurement AC + DC

Digital measured value display via multi-functional LC display

LEDs: Power On, Alarm1 and Alarm2

Fault memory for the operating value

Cyclical self monitoring

Internal test/reset button

Two separate alarm relays (one changeover contact each)

N/C or N/O operation and fault memory behaviour selectable

Password protection for device settings

Sealable transparent cover

Available with screw-type or push-wire terminals
