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, half- wave sinusoidal averaging to achieve a display reso- lution 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 ac- curate, high-voltage, ac line monitoring.
