| DMS-20PC-4/5/6-DCM Self-Powered LED Display, Negative Input DC Voltage Monitor FEATURES Self-powered, only two connections required -4.5 to -20Vdc, -18 to -50Vdc, and -30 to -264Vdc models Can be used with positve-reading DMS-20PC-DCM's Ultra-low power consumption (8mA typ.) 0.37"/9.4mm high, bright red, LED displays Subminiature 1.38" x 0.88" x 1.0" packages 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, 31/2 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.
