MANSFIELD, Mass., 16 July 2009. Murata Power Solutions in Mansfield, Mass., is introducing four-function AC power meters to its line of electronic test and measurement equipment to measure and display power electronics AC volts, amps, Watts and power factor with a typical accuracy of ±0.5 percent full-scale.

The compact, rugged, surface mount ACM20 meters display true-rms voltage and current values of triangle and square waves plus other irregularly shaped waveforms in mains powered applications such as power distribution units, breaker panels, and generator sets in industrial, commercial and residential markets.

A universal 85 to 264 volts AC (@47 to 63Hz) operating voltage allows use worldwide, and users can choose from models with a range of either 0-30 amps (with 0.01 amps resolution, 7200 Watts max.), or 0-100 amps (with 0.1 amp resolution, 9999 Watts max.). Power consumption is less than 0.25 Watts (from a 120 volts AC supply).

A front panel selector switch provides two modes of operation: a fixed reading of any of the four parameters, or a continuous cycling through of all four measurements. An optional model is available that is also able to display line frequency with 0.1 Hz resolution. All ACM20 multi-function power meters include built-in current transformers and require no user supplied components.

The meters have a 0.36-inch four-digit, bright red LED display, which can be read from as far away as five meters. For more information contact Murata Power online at www.murata-ps.com.
