ACM3P-4-AC1-B-C

ACM3P-4-AC1-B-C is a ACM3P series three-phase AC ammeter. It measures 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. It functionally complete, with built-in L1, L2, and L3 current transformers no other user-supplied components or hardware are required. This 85 to 264VAC (47 to 63Hz) operating supply range make this ammeter perfect for worldwide 3-phase current monitoring applications. And, unlike conventional average-responding products, it can accurately display the true-rms values of triangle waves, square waves, and other irregularly shaped AC current waveforms, with an accuracy of ±2% of full scale. This unit is packaged in a one-piece, vibration resistant, polycarbonate housing that can be installed in vertical ‘0U’ or horizontal ‘1U’ rack spaces.
