Technical Information

Series DMU-30DCV
Series Headline Ruggedized DC Voltmeters with Daylight Readable Auto-Dimming LED Displays
Series Description Murata Power Solutions' DATEL branded DMU-30DCV series of daylight-readable dc voltmeters measure and display dc signals as low as +/-200mV and as high as +/-200V. Their large 0.56'' (14.2mm) high super-bright red LED-display is readable in full sunlight. An auto-dimming circuit automatically adjusts the display brightness for all viewing conditions. DMU-30DCV series dc voltmeters are packaged in a rugged, one-piece polycarbonate plastic housing that features an integrated bezel and gasket assembly. In a typical installation, the housing is secured to a panel with six metallic threaded inserts, allowing the unit to meet NEMA-4 / IP65 requirements for moisture and impact resistance in outdoor applications. DMU-30DCV series dc voltmeters are available in a choice of four input ranges: +/-200mVdc (with 0.1mV resolution); +/-2Vdc (0.001V resolution); +/-20Vdc (0.01V resolution); and +/-200Vdc (0.1V resolution). The dc signal under measurement is electrically isolated from the unit's operating power source. DMU-30DCV series' miniature size and rugged package are perfect for industrial and high-reliability instrumentation, alternative power generators, and any other application which requires daylight readability and precise monitoring of dc voltages in harsh indoor / outdoor environments. Simply connect the input signal and an 85-264Vac source of operating power to the two rear-mounted terminal blocks and the unit is fully operational.
