Low power consumption
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 dis-
play, 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,
epoxy-encapsulated, 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.
