PMC72S 3 Phase Multifunctional Power Meter

PMC72S meter is a multi-functional power monitoring meter, it combines function of collecting data and control, and it can replace many kind of meters, relays, transformers and others components. PMC72S can be installed in different positions of electricity distribution system.

PMC72S is designed with RS-485 communication interface, which enable itself to be integrated into a variety of power monitoring systems. Data acquisition and remote control can be easily performed through the supporting management software or other industrial configuration software.

PMC72S 3 Phase Multifunctional Power Meter

Description:

PMC72S is a true RMS-based measuring meter that can accurately measure highly nonlinear loads. Its advanced grid frequency synchronization sampling technology enables it to accurately measure a variety of power parameters, including voltage/current RMS, frequency, active power, reactive power, apparent power, power factor, input/output active energy, total active energy, Input/output reactive power, total reactive power, apparent power, voltage total harmonic distortion (THD), 1~31 voltage harmonics, current total harmonic distortion (THD) and 1~31 current harmonics, etc. . All measurement values, min value and max value, and demand measurement values can be viewed on the screen display or be checked via remotely software control. Overview of Meter functions Table 1
