 1.Features

Using the ac sampling technique and effective value algorithm, the distortion waveform can be measured accurately.

★The sampling frequency is as high as 8kHz, high harmonics, can still be measured accurately, can satisfy most industrial electric power environment.

★Fixed frequency sampling, each sampling value participates in the energy accumulation, the power meter is not affected by the frequency fluctuation of the power grid.

★Current time tracking of the frequency variation of the grid, based on the sampling algorithm of fixed-frequency tracking, ensures that the current, voltage, power and other valid values are not spectrum leaked by the fixed frequency sampling.

★The phase difference between the transformer and the distribution capacitance is compensated by the digital transfer technique, and the accurate measurement is guaranteed under the condition of low power factor.

★The instrument adopts high reliable, high performance and industrial-grade components.

★Variable ratio can be set, also can extend switch quantity input, switch quantity output, analog quantity output and communication function.

★It can realize limit alarm output.

★The transmission output range can be 0～10 mA、0～20 mA、4mA～20mA.(default 4mA～20mA )

★Standard RS-485 communication port、MODBUS-RTU communication agreement, The baud rate is 1200 ~ 19200(default 9600bps)
