Functional characteristics
Complete protection function
With over voltage, under voltage, over current, over temperature, harmonic protection and other functions, when the grid parameters exceed the set limit, the capacitor can be quickly removed to extend the service life of the capacitor;
Multipoint sampling technique
Using MCU microelectronic control circuit technology to determine reactive power trend and flow, automatically controlling the switching process based on preset parameters and reactive power levels to prevent switching oscillations;
Specialized metering chip
The special power metering chip is used to measure the grid parameters with high precision, and the LCD screen dynamically displays the three-phase voltage, current, reactive power, active power and power factor of A, B and C.
Encoding cycle switching
Adopt the code cycle mode, the same capacity of the cycle switching in order, the capacity of different by code dynamic adaptation compensation, improve the compensation accuracy, with less action times to obtain the best compensation effect;
Communication control function
The use of network line 485 communication control protocol, easy to install and use, fast communication rate;
Man-machine dialogue function
Backlight LCD display and anti-interference single chip microcomputer are used to ensure the reliable operation of the product.
