Self-Powered, Positive Input
LED Display, DC Voltage Monitors
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)
and +30-264Vdc (1V resolution). Built-in reverse
polarity protection assures simple, trouble-free
installation.
All DMS-20PC-DCM's employ a high-resolution,
3 digit A/D converter and precision metal-film
resistors to achieve outstanding performance over an
operating temperature range of 25 to +60C.
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.
