True RMS Voltmeters Measure Complex AC

The company’s family of DATEL voltmeters claim to overcome the limitations of conventional average-responding AC voltmeters with the capability to measure the true-rms value of complex AC voltages. With an input frequency range of 47 Hz to 1 kHz, the series suits a wide range of applications including high-end consumer electronics and laboratory instrumentation. The four-wire DMS-20RM series is available with a choice of three input ranges: 20 Vac with 0.01V resolution, 200 Vac with a 0.1V resolution, and 300 Vac with a 1V resolution. Modules are available that operate from a supply voltage of either 85 to 264 Vac or 10 to 40 Vdc. No external isolation transformers or auxiliary power supply conditioning components are required.
