Digital power meter ACM20 series

panel-mountmulti-function

Murata Power Solutions’ ACM20 series AC power meters display the most critical measurements in mains-powered equipment: voltage, amperage, active power (watts), and power factor. 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. An optional model displays line frequency with 0.1Hz resolution. All ACM20 multi-function power meters include built-in current transformers—no other user-supplied components are required. ACM20 series AC power meters are available in a choice of three input ranges: 0-10A (with 0.001A resolution, 999.9 watts max.); 0-32A (with 0.01A resolution, 9999 watts max.); and 0-100A (0.1A resolution, 26.4kW max.). An 85-264Vac (47-63Hz) operating supply range makes these power meters perfect for worldwide power monitoring applications. And, 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. Their large (0.36"/9.2mm), bright red LED display makes ACM20 AC power meters easily readable from as far as 15 feet (5 meters). All units are packaged in a one-piece, vibration resistant, polycarbonate housing that can be installed in vertical ‘0U’ and ‘1U’ rack spaces. Their miniature size is perfect for UPS power sources, power strips, laboratory instrumentation, alternative energy applications, and any other products that require precise monitoring of AC power.
