08:41Ruggedised panel-mount voltmeter
The ruggedized, daylight readable DMU-30ACV / DCV series of panel mount, digital voltmeters from Murata Power Solutions is for applications in harsh environments. The 85VAC - 264VAC mains, or 110VDC - 300VDC battery powered meters are suitable for use in operating temperatures ranging from -25ºC to +60ºC.

The DMU-30ACV / DCV series comprises three AC models capable of measuring up to 20VAC, 200VAC and 300VAC, and four DC models with ranges up to 200mVDC, 2VDC, 20VDC and 200VDC. Flexible inputs provide 2000V isolation between power source and input signal, and allow true-rms measurement of complex waveforms plus simple 2-wire operation for AC mains monitoring.

The super-bright, three-and-a-half digit red LED display is readable in direct sunlight with no shading devices and automatically adjusts brightness for indoor or night time viewing. An externally accessible adjustment for minimum intensity is also provided. The DMU-30ACV / DCV series has a power consumption of typically 1W in full sunlight and 0.1W at night

The one-piece polycarbonate housing with integrated red bezel and gasket is designed to meet NEMA-4 / IP65 moisture resistance requirements.
