Function Feature

This meter adopts the five-row LED display equipped with the way of status indicators take turnsto show to real-time measure and display the various electric parameters of three-phase electric circuits, such as voltage, current, frequency, power, power factor, four quadrant energy, and soon. It also provides the functions of demand indication, maximum value record, minimum value record, and so on.  

★Short shell design, compact, economical and practical.
★True RMS measurement, frequency and waveform change will not influence the accuracy of measurement.
★It can display directly multiple electric parameters at the same time.
★PT and CT ratio can be set.
★Statistics of extreme values and demand indication, and the demand slip time can be set.
★Buckle mounting way make the installation efficient, firm and reliable.
★It can extend one channel RS485 communication interface, MODBUS-RTU communication protocol.
