描述 Description

Murata Power Solutions’ new DMR20-10-DCM self-powered, auto-ranging DC voltagemonitors are designed to measure and display the outputs the most popular DC powersystems. 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 (3meters). These auto-ranging meters accurately display DC voltages with 0.01V in the LORange (below 51V), or 0.1V resolution in the HI Range (above 51 V). A built-in resettablefuse assures long term reliability. All DMR20-10-DCM’s employ a 13-bit A/D converterand precision metal-fi lm resistors to achieve outstanding performance over an operatingtemperature range of –25 to +60°C.The DMR20-10-DCM is housed in a rugged, round polycarbonate case that provides excellentprotection against moisture, dust, shock and vibration. Panel installation is straightforward:using readily available tooling, simply drill and punch a 1.2 inch (30.5mm) diameterhole and anti-rotation notch, insert the meter and gasket into the panel, and securely fastenthe meter using the supplied hex nut. The supplied hardware is designed to provide protectionto IP67/NEMA 6.
