Very 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 DMS-20PC-1-LM-F sinusoidal averaging (rms calibrated) and has (Blade Terminals) a display resolution of 1Vac over its full input 8C48 range. Packaged in a red-filter case with builtin bezel, the meter is fully encapsulated for ruggedness. All units are overvoltage protected to 300Vac. This low-cost meter is ideal for industrial, laboratory, office and field-service applications. Its miniature size is perfect for design DMS-20PC-1-LM into high-end consumer electronics, laboratory (Panel Mount) instrumentation and other products requiring accurate ac line monitoring.

DMS-20PC-1-LM Self-Powered 3 Digit, LED Display AC Line Voltage Monitors Power Supply Polarity, Grounding, Fusing, and Wiring 1. Polarity and Grounding: DMS-20PC-1-LM’s two ac-supply input terminals are not polarity sensitive, that is, they have no “AC LO” or “AC HI” designations. These units do not include nor require a connection to earth/chassis ground. All ac-supply wiring must be rated for the voltages and currents they will conduct and comply with any code or application-mandated requirements pertaining to the user’s specific installation.
