The APM830 is a high-precision, multifunctional power monitoring meter designed in accordance with IEC standards for industrial-grade power quality and energy management. It supports full electrical parameter measurement, advanced power quality analysis, transient event capture, and multi-rate energy statistics. With a modular design, the APM830 allows expansion via DI/DO modules, analog I/O, TF card logging, and multiple communication protocols (RS485, Profibus, Ethernet). Its vector analysis, waveform capture, and real-time harmonic monitoring make it ideal for critical energy distribution systems across utilities, factories, data centers, and commercial complexes.
