Murata Power Solutions’ DMS-20PC-DCM Series of self-powered, positive-reading, dc voltage monitors are great replacements for older, hard-to-read, analog panel meters. Simply connect a positive dc voltage across the rear terminals and the meters are fully operational — no additional components or power supplies are required!  The large, 0.37"/9.4mm, LED displays can be easily read | from 15 feet away.  Four versions are available: +4.5019.99Vdc (0.01V resolution), +8.0-50.0Vdc (0.1V resolution), +30.0-199.9Vdc (0.1V resolution)  and +30-264Vdc (1V resolution).  Built-in reverse polarity protection assures simple, trouble-free installation. 

All DMS-20PC-DCM's employ a high-resolution, 3½ digit A/D converter and precision metal-fi lm resistors to achieve outstanding performance over an operating temperature range of –25 to +60°C.  A rugged, ‘o) epoxy-encapsulated, polycarbonate case provides excellent protection against moisture, shock and mw 4% vibration. The DMS-20PC-DCM's are designed to fit the same panel cutout as Murata Power Typical panel mount installation and Solutions’ popular DMS-20PC-X-LM ac-line voltage suggested wiring (user supplied). monitors.
