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
N
Self-powered, two-terminal operation
N
Dual operating ranges: 240-310Vac at 50/60Hz or
85-140Vac at 400Hz
N
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.
N
Large, easy-to-read, bright red LED display
N
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.
N
Built-in bezel for panel mounting
N
Reliable screw terminals for easy installation
N
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
