Murata Power Solutions’ 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
a display resolution of 1Vac over its full input
