DMS-20PC-1-LM Self-Powered 3 Digit, LED Display AC Line Voltage Monitors FEATURES N Plugs directly into USA-style wall outlets N Screw terminals for panel mounting N Small 1.38" x 0.88" x 1.0" packages N Large, easy-to-read, red, blue or green LED displays N Fully encapsulated for harsh environments N Half-wave averaging, rms calibrated N UL, CSA and IEC1010-1 certified N Very low cost! 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 builtin 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 applications. Its miniature size is perfect for design into high-end consumer electronics, laboratory instrumentation and other products requiring accurate ac line monitoring.
