DATEL's new 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 opera-
tional 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 perfor-
mance over its operating temperature range of –25 to
+60°C. A rugged, epoxy-encapsulated, polycarbon-
ate case provides excellent protection against
moisture, shock and vibration.
Suggested wiring
(User supplied)
The DMS-20PC-3-DCM uses the same panel
cutout dimensions as all DMS-20 Series panel voltme-
ters and monitors; this feature assures uniform displays in
multiple-meter applications.
