Murata Power Solution's DMS-20PC-1-LM is a component-size, self-contained, low-cost
ac voltmeter for true line measurements. It requires no additional components or auxiliary
power. Simply plug it into any wall outlet and instantly read voltages from 85 to 264Vac
(47-63Hz). The large (0.37"/9.4mm), bright red, blue or green LED display makes the
DMS-20PC-1-LM easily readable under any lighting conditions.
DMS-20PC-1-LM employs half-wave
sinusoidal averaging (rms calibrated) and has
DMS-20PC-1-LM-F
a display resolution of 1Vac over its full input
(Blade Terminals)
range. Packaged in a red-filter case with built-
in bezel, the meter is fully encapsulated for
ruggedness. All units are overvoltage protected
DMS-20PC-1-LM
(Panel Mount)
to 300Vac.
This low-cost meter is ideal for industrial,
laboratory, office and field-service applica-
tions. Its miniature size is perfect for design
into high-end consumer electronics, laboratory
instrumentation and other products requiring
accurate ac line monitoring
.
