Panel RMS voltage indicator DMV-1AC-MBT

Panel RMS voltage indicator DMV-1AC-MBT

Product Description:

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

Operation:

The device is equipped with two independently configurable alarms that control the operation of two change-over contact relays. Each alarm has a configurable lower and upper trip threshold and hysteresis. The lower alarm threshold can be set in the range of 10÷479 V, while the upper alarm threshold can be set in the range of 11÷480 V. The hysteresis is set in the range of 1÷150 V. Alarm states are indicated by two red LEDs (A1 and A2) on the front of the device.
