Function Feature

It adopts the three-row four-digit LED display and status indicator to real-time measure and display the voltage, current, frequency, power, four-quadrant electrical energy and so on electric parameters of three-phase electric circuits. It also adopt simplified design scheme, with high cost performance.
★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.
★Variable ratio can be set.
★It can extend one channel RS485 communication interface, MODBUS-RTU communication protocol.
★Buckle mounting way makes the installation efficient, firm and reliable.
