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
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.
DMS-20PC-2-LM employs half-wave sinusoidal
averaging (rms calibrated) to achieve a display resolution 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.
This low-cost, extremely versatile digital voltmeter 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
monitoring.
