Murata DMS-20PC-3-LM-C Self-powered led display 480v ac line monitor Datasheet

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.
DMS-20PC-3-LM employs rms calibrated, halfwave sinusoidal averaging to achieve a display resolution of 1Vac over its full operating range. Packaged
in a subminiature (1.38˝ x 0.88˝ x 1.0˝) 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.
This easy-to-use, vibration-proof voltmeter is the
ideal digital upgrade for fragile analog-style panel
meters in 480Vac power distribution equipment. It
similarly excels in any new application requiring accurate, high-voltage, ac line monitoring.
