DMS-20PC-3-LM
Actual Size
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 DMS20PC-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 Typical panel mount installation 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 Suggested wiring encapsulated for ruggedness. An optional bezel (User supplied) 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.
