The APM Series by Acrel consists of advanced multifunction power meters designed for comprehensive power monitoring and power quality analysis in electrical distribution systems. Available in various models—APM800, APM801, APM810, and APM830—they provide real-time, four-quadrant energy metering, support multi-rate tariffs, and analyze harmonics up to the 63rd order. With expandable I/O, RS485, Profibus, and Ethernet communication, the APM Series meters are ideal for industrial, commercial, and utility-grade power quality supervision.
