Autonics Corp MT4W-DV-44 Digital Panel Meter 4-digit 14.2mm DC Voltage 0-500V 100-240VAC

Digital Panel Meter for DC Voltage Monitoring

The Autonics MT4W-DV-44 is a digital panel meter designed for electricians and technicians who need to monitor DC voltage levels in industrial panels or test equipment. It mounts in a standard cut-out and provides a clear local readout without requiring a separate handheld instrument. Buyers who need AC voltage or current measurement should select a different model.

Four-Digit LED Display with 14.2 mm Characters

The single specification that decides suitability is the 4-digit 7-segment LED display with a character height of 14.2 mm and a maximum range of -1999 to 9999. This resolution covers the full 0-500 V input span as well as the lower ranges down to 50 mV. Panels that require more digits or a different character size will not match this unit.

Stable Readings Across Eight Input Ranges

Under sustained load the meter maintains its stated accuracy across eight selectable DC input ranges from 0-500 V down to 0-50 mV while powered from a 100-240 VAC 50/60 Hz supply. The fixed ranges prevent autoranging delays during long-term monitoring, and the wide AC supply tolerance keeps the display steady through mains fluctuations.
