Murata Power Solutions DMR20 Series Digital Voltmeter DC, 30.73 mm Cutout, 27.4 mm Depth, 60°C Max Operating Temperature

Murata Power Solutions DMR20-10-DCM-R-C Digital Voltmeter DC is a high-performance, self-powered, and auto-ranging DC voltage monitor designed for industrial, laboratory, and process control applications. The device measures and displays DC voltages with precise resolutions of 0.01 V in the low range and 0.1 V in the high range, supported by a 13-bit A/D converter and precision metal-film resistors to ensure outstanding accuracy.

The meter’s large 7.6 mm bright LED display is clearly visible from up to 3 meters, facilitating easy voltage monitoring in electrical panels. Its compact design fits into a round 30.73 mm oil-tight cutout and a shallow 27.4 mm depth, allowing installation in tight panel spaces.

Constructed with a rugged polycarbonate housing, the voltmeter is resistant to moisture, dust, shock, and vibration, meeting IP67 and NEMA6 ingress protection ratings. It includes a resettable internal fuse and reverse polarity protection up to 100 VDC to safeguard the unit and extend operational life.

This unit operates from supply voltages between 6 VDC and 75 VDC and supports maximum operating temperatures of 60°C, making it suitable for demanding industrial environments. The device is supplied with an EPDM rubber gasket and plastic hex nut to secure installation in panels, with optional panel knockout punches and tooling available.

The Murata DMR20 series serves as a digital replacement for analogue panel meters, delivering precise voltage readings for various applications in industrial automation, manufacturing, electrical power distribution, and laboratory instrumentation. Its fast auto-ranging capability and self-powered operation reduce wiring complexity and enhance system reliability.
