Summery : This series of meter can measure the electrical parameter of current, voltage, power, power factor, etc under AC sampling condition, also can set times rate, communication address and baud rate through panel film switching. With RS-485 communication interface, Modbus protocol, can output DC current analog signal from electric signal. For K1 and K2,the transmitting output of measuring number is optional, the output of 4`20 m A, 0~5V, 4`12`24 m A is optional This series of meters are used in many industries and have strong function of combination. For example, three-phase energy meter can measure the power directly, measure the AC phase voltage,virtual value of current, frequency and other parameter through keyboard switch.
