Voltmeters measure down to 0 V via AC or DC supply.
March 17, 2009 -
DATEL DMS-20RM voltmeters measure true-rms value of complex AC voltages and triangle waves, square waves, or other irregularly shaped waveforms with ±0.4% accuracy. Independent power supply is fully isolated, up to 2 kV, from input AC signal and 1.38 x 0.88 x 1.00 in., 4-wire device includes rugged polycarbonate housing and 3½-digit, 0.37 in. LED display. Operating temperature range is -25 to +60ºC and measurement range is up to 12 ft. Input ranges of 20, 200, and 300 Vac are available.
Fully Integrated True-RMS Voltmeters Measure to 0 V for Complex AC Voltages
o 20VAC, 200VAC and 300VAC input ranges
o Range offers choice of AC and DC operating supply options
o Overcomes limitations of conventional average responding AC Voltmeters
o Rugged, encapsulated design provides moisture and vibration resistance
o 9.4mm three-and-a-half digit bright red LED display
Murata Power Solutions has introduced a new series of DATEL Voltmeters that overcome the limitations of conventional average-responding AC Voltmeters. The DATEL DMS-20RM series is able to measure the true-rms value of complex AC voltages and, with an input frequency range of 47 - 1kHz, is ideal for use in a wide range of applications including high-end consumer electronics, laboratory instrumentation and other equipment requiring precise AC line monitoring.
Conventional average-responding AC Voltmeters are limited in that they only produce accurate readings when measuring ideal sine-wave voltages. The DMS-20RM series can also measure and accurately display the true-rms value of triangle waves, square waves or other irregularly shaped waveforms with a full scale accuracy ±of 0.4%. Also, unlike average-responding AC Voltmeters, the new modules from Murata Power Solutions are able to measure down to 0V as they use their own integrated, independent power supply that is fully isolated (up to 2kV) from the input AC signal.
The four-wire DATEL DMS-20RM series is available with a choice of three input ranges of 20VAC (with 0.01V resolution), 200VAC (0.1V resolution) or 300VAC (1V resolution). Depending on their application, customers can choose modules that operate from a supply voltage of either 85 to 264VAC or 10 to 40VDC. No external isolation transformers or auxiliary power supply conditioning components are required for the fully self-contained modules.
Rugged, fully encapsulated polycarbonate housings make the DMS-20RM series both moisture and vibration resistant. A large, three-and-a-half digit 9.4mm (0.37in.) bright red LED display allows easy reading of measurements from distances of up to approximately four meters (12 feet). Overall dimensions of the new modules (excluding PCB) are 1.38in. x 0.88in. x 1.00in. deep (35mm x 22.4mm x 25.4mm deep) and the units are packaged in a red filter case with a built-in bezel. Operating temperature range is -25ºC to +60ºC.
Pricing for DMS-20RM Series AC Voltmeters is $94 in singles and drops to $79.90 at 100 pieces. Small quantities (10) are available from stock; OEM quantities are 12 weeks ARO.
