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. ## ~~CT~~ **Ordering Information** **DMS-20PC-0-DCM-C** +4.50 to +19.99V dc red LED voltage monitor **DMS-20PC-0-DCM-B-C** +4.50 to +19.99V blue LED dc voltage monitor **DMS-20PC-0-DCM-G-C** +4.50 to +19.99V green LED dc voltage monitor **DMS-20PC-1-DCM-C** +8.0 to +50.0V red LED dc voltage monitor **DMS-20PC-1-DCM-B-C** +8.0 to +50.0V blue LED dc voltage monitor **DMS-20PC-1-DCM-G-C** +8.0 to +50.0V green LED dc voltage monitor **DMS-20PC-2-DCM-C** +30 to +264V dc voltage monitor **DMS-20PC-8-DCM-C** +30.0 to +199.9V dc voltage monitor **DMS-20-CP** Panel cutout punch **DMS-BZL3-C** Panel mount bezel assembly **DMS-BZL4-C** Panel mount bezel with sealing gasket Brass screws (6-32 thread) and a panel-mount retaining clip are supplied with each meter **See www.murata-ps.com/dpm-availability for model-specifi c availability.** £25) For full details go to **www.murata-ps.com/rohs** **www.murata-ps.com/support** **MPM_DMS_20PC_0/1/2/8_DCM.F01** Page 1 of 2 ## **- - - DMS 20PC 0/1/2/8 DCM** ## **MECHANICAL SPECIFICATIONS** Self-Powered, Positive Input LED Display, DC Voltage Monitors Dimensions in inches (millimeters) Tolerances: 2 PL Dec ±0.02 (±0.51) 3 PL Dec ±0.010 (±0.254) Recommended panel cutout dimensions: 1.336 (33.93)W × 0.838 (21.29)H Internal corner radii 0.032 (0.81) Max. **==> picture [369 x 399] intentionally omitted <==** **----- Start of picture text -----**
