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 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.
