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.

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.

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.
