Murata Power Solutions extends Datel AC power meter range with industry's first digital low-power panel meters for testing AC-powered products

The ACM20 series of AC power meters display the most critical measurements in mains-powered equipment: voltage, current, active power (watts), and either power factor or frequency, depending on the model. A front panel selector-switch provides two modes of operation: a fixed reading of any of the four parameters, or a continuous cycling through all four measurements. Unlike conventional, average-responding products, ACM20 power meters can accurately display the real power and true-rms current values of triangle waves, square waves, and other irregularly shaped waveforms, with a typical accuracy of ±1% of full scale.

The two additions to the ACM20 series of power meters feature input range of 0-10A (with 0.001A resolution, 999.9 watts max.). As well as voltage, amperage and active power, the ACM20-2-AC1-R-C features power factor measurement functionality, while the ACM20-2-AC1-R-F-C features frequency measurement functionality. Other members of the series are available with input range 0-32A (with 0.01A resolution, 9999 watts max.) or 0-100A (0.1A resolution, 26.4kW max.). An 85-264Vac (47-63Hz) operating supply range makes these power meters perfect for worldwide test and instrumentation applications. All ACM20 multi-function power meters include built-in current transformers - no other user-supplied components are required.

Their large (9.2mm), bright red LED display makes ACM20 AC power meters easily readable from as far as 5 metres. All units are packaged in a one-piece, vibration resistant, polycarbonate housing that can be installed in vertical '0U' and '1U' rack spaces.
