Product details:

Voltage and frequency monitor

for monitoring of 3(N)AC systems up to 0…500 V

for undervoltage, overvoltage, underfrequency, overfrequency,

phase sequence, phase failure, asymmetry

The multi-functional VMD420 series voltage relay is designed to monitor the frequency,

undervoltage and overvoltage and the voltage between two threshold values in 3(N)AC

systems. The voltages are measured as r.m.s. values. The currently measured value is continuously shown on the LC display. The measured value required to trigger the alarm relay is stored. Due to adjustable response times, installation-specific characteristics, such

as device-specific start-up procedures, short-time voltage fluctuations, etc. can be considered. The devices require an external supply voltage.

Once the supply voltage is applied, the start-up delay “t” begins. Measured voltage and

frequency values changing during this time do not influence the switching state of the

alarm relays.

The devices feature two separately adjustable measuring channels (overvoltage/undervoltage). When the measuring quantity exceeds the response value (“Alarm 1”) or falls

below the response value (“Alarm 2”), the time of the response delays “ton1/2” begins.

Once the response delay has elapsed, the alarm relays switch and the alarm LEDs light

up. When the measuring value exceeds or falls below the release value (response value

plus hysteresis) after the alarm relays have switched, the selected release time “toff” begins.

When “toff” has elapsed, the alarm relays switch back to their initial position. When the

fault memory is activated, the alarm relays remain in alarm position until the reset button

“R” is pressed. When the fault memory is set to continuous mode, the alarm parameters

remain stored, even on failure of the supply voltage.
