String Combiner Monitoring
HOME > Multi-parameter > Device for String Combiner Box Monitoring
CE series Multi-channel DC current collector applies to PV combiner box, and used for monitoring the operation of panels. The main function includes photocell current, measuring the voltage, electrical power and electric plating. Also texting the service life, and gathering the operation of DC circuit breaker, relay control output. The device works with RS485, relay and analog outputs, switch input and local LED display.

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-powered(90V-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.
