ACM20 : Murata Power Solutions AC power meter range extends with industry's first digital low-power panel meters for testing AC-powered products

ACM20 : Murata Power Solutions AC power meter range extends with industry's first digital low-power panel meters for testing AC-powered productsMurata Power Solutions has introduced two new models into its ACM20 series of four-function AC power meters. The ACM20-2-AC1-R-C and ACM20-2-AC1-R-F-C are the industry's first digital AC power panel meters with measurement resolution of 0.001A and 0.1W. Their increased resolution makes them ideal for test and instrumentation applications, in particular, for testing a variety of low-current AC-powered products. Ref. MPS 119A 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. Ref. MPS119A
