Murata Power Solutions’ ACM20 series AC power meters display the most critical measure-
ments in mains-powered equipment: voltage, amperage, active power (watts), and power
factor. A front panel selector-switch provides two modes of operation: a fi xed 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 instrumenta-
tion, alternative energy applications, and any other products that require precise monitoring
of AC power.
