DATEL's 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, bright red, LED displays can be easily

read from 15 feet away. Four versions are available:

+4.50-19.99Vdc (0.01V resolution), +8.0-40.0Vdc

(0.1V resolution), +30.0-199.9Vdc (0.1V resolution)

Typical panel mount

installation

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-film

resistors to achieve outstanding performance over an

operating temperature range of –25 to +60°C.

A rugged, epoxy-encapsulated, polycarbonate case

provides excellent protection against moisture,

shock and vibration. The DMS-20PC-DCM's are

designed to fit the same panel cutout as DATEL's

popular DMS-20PC-X-LM ac line voltage monitors.
