DMS-20PC-3-DCM www.murata-ps.com +2 to +11Vdc, Self-Powered LED Display, DC Voltage Monitor FEATURES Self-powered, only two connections required +2.00 to +11.00Vdc input range Murata Power Solutions DMS-20PC-3-DCM self-powered dc voltage monitor is perfect 0.01V resolution 0.05% accuracy for precision monitoring of all low-voltage power supplies. Simply connect a positive dc Ideal for low-voltage (3.3V) power supply monitoring voltage across its two rear terminals and the meter is fully operational with no additional components required A measurement resolution of 0.01Vdc enables precise adjustment Digital replacement for analog panel meters of power supply outputs. The large, 0.37 /9.4mm, bright 0.37 /9.4mm, bright red, LED display red, LED display, unlike most LCDs, can be easily read from Subminiature 1.38 x 0.88 x 1.0 package 15 feet away under virtually any lighting conditions. Built-in reverse polarity protection assures quick, trouble-free instal- Super reliable, epoxy-encapsulated construction lation. Reverse polarity protected The DMS-20PC-3-DCM utilizes a high-resolution, 3 digit 25 to +60C temperature range analog-to-digital converter and precision metal- lm resis- tors to achieve outstanding performance over its operating Low power consumption temperature range of 25 to +60C. A rugged, epoxy- encapsulated, polycarbonate case provides excellent protec- tion against moisture, shock and vibration. The DMS-20PC-3-DCM uses the same panel cutout Functional Speci cations dimensions as all DMS-20 Series panel voltmeters and moni- Input tors this feature assures uniform displays in multiple-meter Voltage Range +2.00 to +11.00Vdc applications.
