DMS-20PC-3-LM

Self-Powered LED Display 480V

AC Line Monitor

DATEL’s DMS-20PC-3-LM is a low-cost, self-powered, 2-wire digital voltmeter

designed for monitoring 480Vac 3-phase primary power. The DMS-20PC-3-LM’s unique

power-supply design allows a single model to operate

from 350 to 600Vac (47-63Hz). The meter requires no

external components or auxiliary power for full operation!

Its large, 0.37˝/9.4mm, bright red LED display is easily

readable under virtually all lighting conditions.

FEATURES

Self-powered, two-terminal operation

350 to 600Vac operating input range

Half-wave averaging, rms calibrated

Large, easy-to-read, bright red LED display

DMS-20PC-3-LM employs rms calibrated, half-

Rugged, epoxy-encapsulated construction

wave sinusoidal averaging to achieve a display reso-

lution of ±Vac over its full operating range. Packaged

in a subminiature (±.38˝ x 0.88˝ x ±.0˝) red-ﬁlter case

with a built-in bezel, the meter is epoxy encapsulated

for ruggedness. An optional bezel assembly, featuring

metal fasteners, simpliﬁes panel mounting.
