DMS-20RM-3-AC1-R-C

3.5 Digit, AC-Powered, Standard Red LED, AC rms Voltmeter: 0-300Vac @ 47 - 1000Hz input
DMS-20RM-3-AC1-R-C
Series Headline True-rms ac Voltmeters with Isolated Inputs
Series Description Murata Power Solutions' DMS-20RM series are four-wire, self-contained ac voltmeters that measure and display the true-rms values of complex ac waveforms. Because the input circuitry is electrically isolated from the unit's operating power source, these voltmeters can measure signals down to zero volts. No external isolation transformers or auxiliary power supply conditioning components are required. Simply connect the input signal and a source of operating power (85-264Vac, or an optional +10-40Vdc) to the two rear-mounted terminal blocks and the unit is fully operational. DMS-20RM rms voltmeters are available in a choice of three input ranges: 20Vac (with 0.01V resolution); 200Vac (0.1V resolution); and 0-300Vac (1V resolution). An input frequency range of 47-1kHz makes these voltmeters ideal for all ac voltage monitoring applications. And, unlike conventional, average-responding products, these meters can measure and accurately display the true-rms value of triangle waves, square waves, or other irregularly shaped waveforms with 0.4% full-scale accuracy. The large (0.37''/9.4mm), bright red LED display makes the DMS-20RM ac voltmeters easily readable from as far as 12 feet (4 meters). All units are packaged in a red-fi lter case with a built-in bezel; these meters are fully encapsulated to make them moisture and vibration resistant. Their miniature size is perfect for high-end consumer electronics, laboratory instrumentation, alternative power generators and other products requiring precise ac line monitoring.
