DATEL’s DMS-20PC-DCM Series of self-powered, negative-reading, dc voltage monitors
are great replacements for older, hard-to-read, analog meters. Simply connect a negative
voltage across the rear terminals and the meters are fully operational! Negative-input
DCM’s can be easily combined with positive-reading DMS20PC-DCM’s for monitoring dual-polarity power supplies.
Three versions are available: one for –4.50 to –19.99Vdc
(0.01V resolution), one for –18.0 to –50.0Vdc (0.1V resolution),
and one for –30 to –264Vdc (1V resolution). Their large,
0.37”/9.4mm, bright red LED displays can be easily read
from 15 feet away. 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.
