Murata Power Solutions’ new DMR20-10-DCM self-powered, auto-ranging DC voltage monitors are designed to measure and display the outputs the most popular DC power systems. Simply connect any 6 to 75V DC power source and these meters are fully operational—no additional components or power sources are required.
Their large, 0.30"/7.6mm, bright LED displays can be easily read from 10 feet away (3 meters). These auto-ranging meters accurately display DC voltages with 0.01V in the LO Range (below 51V), or 0.1V resolution in the HI Range (above 51 V). A built-in resettable fuse assures long term reliability. All DMR20-10-DCM’s employ a 13-bit A/D converter and precision metal-film resistors to achieve outstanding performance over an operating temperature range of –5 to +60°C.
The DMR20-10-DCM is housed in a rugged, round poly carbonate case that provides excellent protection against moisture, dust, shock and vibration. Panel installation is straightforward: using readily available tooling, simply drill and punch a 1.2 inch (30.5mm) diameter hole and anti-rotation notch, insert the meter and gasket into the panel, and securely fasten the meter using the supplied hex nut. The supplied hardware is designed to provide protection to IP67/NEMA 6.
