DATEL’s DMS-20PC-3-DCM self-powered dc voltage monitor is perfect for precision
monitoring of all low-voltage power supplies. Simply connect a positive dc 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 of power supply
outputs. The large, 0.37"/9.4mm, bright red, LED display,
unlike most LCD’s, can be easily read from 15 feet away
under virtually any lighting conditions. Built-in reverse polarity protection assures quick, trouble-free installation.
The DMS-20PC-3-DCM utilizes a high-resolution, 3 digit
analog-to-digital converter and precision metal-film resistors to achieve outstanding performance over its operating
temperature range of –25 to +60°C. A rugged, epoxyencapsulated, polycarbonate case provides excellent protection against moisture, shock and vibration.
The DMS-20PC-3-DCM uses the same panel cutout
dimensions as all DMS-20 Series panel voltmeters and monitors; this feature assures uniform displays in multiple-meter
applications.
