DMS-20PC-0/1/2/8-DCM www.murata-ps.com Self-Powered, Positive Input LED Display, DC Voltage Monitors FEATURES Self-powered, only two connections required +4.50-19.99Vdc, +8.0-50.0Vdc, +30.0-199.9Vdc Murata Power Solutions DMS-20PC-DCM Series of self-powered, positive-reading, dc and +30-264Vdc models voltage monitors are great replacements for older, hard-to-read, analog panel meters. Ideal replacements for analog panel meters Simply connect a positive dc voltage across the rear ter- Ultra-low power consumption (8mA typ.) minals and the meters are fully operational no addi- tional components or power supplies are required The 0.37 /9.4mm high, red or blue, LED displays large, 0.37 /9.4mm, LED displays can be easily read Subminiature 1.38 x 0.88 x 1.0 packages from 15 feet away. Four versions are available: +4.50- Super reliable, epoxy-encapsulated, construction 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. Functional Speci cations All DMS-20PC-DCM s employ a high-resolution, 3 Input digit A/D converter and precision metal- lm resistors Voltage Range: to achieve outstanding performance over an operat- DMS-20PC-0-DCM +4.50 to +19.99Vdc DMS-20PC-1-DCM +8.0 to +50.0Vdc ing temperature range of 25 to +60C. A rugged, DMS-20PC-2-DCM +30 to +264Vdc epoxy-encapsulated, polycarbonate case provides DMS-20PC-8-DCM +30.0 to +199.9Vdc excellent protection against moisture, shock and Current Consumption: vibration.
