Digital ammeter ACM3P-4-AC1 series

ACthree-phasepanel-mount

Murata Power Solutions’ ACM3P series 3-phase AC ammeters measure and display the true-rms values of 2- or 3-phase ac mains current. A front panel touch switch enables the selection of a continuous reading of any of the three phases. All ACM3P ammeters are functionally complete, with built-in L1, L2, and L3 current transformers—no other user-supplied components or hardware are required. ACM3P series AC ammeters are available with a 0-100A input range (150A peaks) and provide a resolution of 0.1 Amp. Their 85-264Vac (47-63Hz) operating supply range makes these ammeters perfect for worldwide 3-phase current monitoring applications. And, unlike conventional average-responding products, ACM3P ammeters can accurately display the true-rms values of triangle waves, square waves, and other irregularly shaped AC current waveforms, with an accuracy of ±1% of full scale. Their large (0.36"/9.2mm), bright LED display, available in a choice of red, blue, or green, enables ACM3P ammeters to be 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’ or horizontal ‘1U’ rack spaces. Their miniature size is ideal for UPS backup power sources, power strips, alternative energy metering, and any other applications that require precise monitoring of 2- or 3-phase ac current. FEATURES „ Measure and display the true-rms current of 3-phase power systems „ Three built-in current transformers measure up to 100A per phase „ Ideal for power distribution units (PDUs) and backup power systems „ Low power consumption: less than ¼watt from 120Vac supply
