Panel voltage indicator DMV-1AC-MBT

Panel voltage indicator DMV-1AC-MBT

DMV-1AC-MBT,

Product description

The DMV-1AC-MBT panel meter is used for measurement of AC voltage effective value (RMS) in the range of 10÷480 V AC.
The result of the measurement is shown on a numerical LED display with a digit height of 14 mm. The measuring channel is galvanically isolated and allows measurement on an independent circuit.

Functioning
The device is equipped with 2 independently configured alarms, which control the operation of two relays with a switching contact. Each of the alarms has a configurable lower and upper activation threshold and hysteresis. The lower alarm threshold can be set in the range of 10÷479 V, and the upper one in the range of 11÷480 V. The hysteresis is set within the range of 1÷150 V. Alarm status is indicated by two red LEDs (A1 and A2) on the front of the device.
