DMS-20PC-2-LM

Self-Powered LED Display High-Voltage,

50/60/400Hz AC Line Monitor

DATEL’s DMS-20PC-2-LM is a component-size, self-contained, low-cost ac voltmeter

speciﬁcally designed for high-voltage or high-frequency operation. The DMS-20PC-2-LM’s

unique power-supply circuitry allows a single model to

operate from either 240 to 310Vac with 50/60Hz inputs or

from 85 to 140Vac with 400Hz inputs. The meter requires

FEATURES

Self-powered, two-terminal operation

Dual operating ranges: 240-310Vac at 50/60Hz or

85-140Vac at 400Hz

Half-wave averaging, rms calibrated

no external components or auxiliary power for full opera-

tion! Its large, 0.37"/9.4mm, bright red LED display is

easily readable under virtually all lighting conditions.

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

Rugged, epoxy-encapsulated construction

DMS-20PC-2-LM employs half-wave sinusoidal

averaging (rms calibrated) to achieve a display resolu-

tion of 1Vac over its full operating range. Packaged in

a red-ﬁlter case with a built-in bezel, the meter is epoxy

encapsulated for ruggedness.

Built-in bezel for panel mounting

Reliable screw terminals for easy installation

Small 1.38" x 0.88" x 1.0" package

This low-cost, extremely versatile digital voltme-

ter is ideal for use in emergency power equipment,

277Vac ﬂuorescent lighting systems, 400Hz aircraft

installations, and any other application requiring

accurate, high-voltage or high-frequency, ac line
