AC voltmeter / digital - 0 - 19.99 V, 47 - 1 000 Hz | DMS-20RM-1-AC1-R-C
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. Due to the input circuitry being 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. You needs to 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 including 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.
Unlike the conventional 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.
