    Measured by Hall sensor and the maximum current is 30A;

    Hole-tru input, more convenient and high safety;

    Current has bipolar measurement, which used for measuring the positive and negative;

    Provide two standards analog signal input with 0-10Vand 0-20mA. That can easy to transfer other sensor signal;

    Can measure the voltage of PV modules, the maximum voltage is DC 1KV;

    Power supply used solar battery voltage with self-powered90­V-1000V D,which is better in on-site construction;

    With local LED display and has LED indicator reminder function with each current operation and short circuit;

    With small volume, can be measured with 24 channel current;

    RS485 output with Modbus-RTU protocol.


    Short circuit of the solar panel alarmed by LED display and data transmission;

    Switch input for DC breaker or lightning device status monitoring;

    Relay output for automatic control of DC breaker switch on and off;

    Provide the temperature sensor, radiation sensor, and wind speed sensor with analog input (4-20mA/0-5V) Interface;

    Output 12V or 24Vdc power for the extra environment sensors;

    6 digit LED display each channel current in circle, with power saving mode;

    Modbus RTU protocol, address, baud rate and data mode can be modified according the conditions. The setting mode includes local DIP switch setting and remote communication settings;

    Can measure the battery voltage after confluence, and also can calculate the power and electric.
