MPM_DMS_20PC_0/1/2/8_DCM.F01 Page 1 of 2
FEATURES
Self-powered, only two connections required
+4.50-19.99Vdc, +8.0-50.0Vdc, +30.0-199.9Vdc
and +30-264Vdc models
Ideal replacements for analog panel meters
Ultra-low power consumption (8mA typ.)
0.37"/9.4mm high, red or blue, LED displays
Subminiature 1.38" x 0.88" x 1.0" packages
Super reliable, epoxy-encapsulated, construction
Brass screws (6-32 thread) and a panel-mount retaining clip are supplied with each meter
➀ Operation and accuracy at inputs above or below these ranges
are not specifi ed.
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 ter-
minals and the meters are fully operational — no addi-
tional 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: +4.50-
19.99Vdc (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 operat-
ing 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 Murata Power
Solutions’ popular DMS-20PC-X-LM ac-line voltage
monitors.
