RMD series of multi-function power meters
1.1 Overview
RMD series multi-function power meter is designed for power monitoring needs of high automation level such as power system, industrial and mining enterprises, petrochemical industry, iron and steel metallurgy, intelligent building and so on. Can measure all three-phase power grid power parameters such as three-phase voltage, three-phase current, active power, reactive power, power factor, power frequency, two-way power, harmonics and so on. With standard power pulse output and RS485 communication interface. Optional a variety of extended function modules such as analog transmitter output, digital input monitoring, digital output and other functions. This series of products has a very high cost performance, you can directly replace the conventional power transmitter, measuring instrumentation, energy meters and related auxiliary units. As an advanced intelligent, digital power grid front-end acquisition components, the series of instruments have been widely used in various control systems, SCADA systems and energy management systems.
