Functional characteristics
Dynamic detection function
Automatically detect the quantity and capacity of compensation devices, control the switching according to reactive power parameters; Dynamically display the parameter values of power distribution, with simple and fast parameter settings, and the set parameters will not be lost when the power is turned off;
Complete protection function
With over voltage, under voltage, over current, under current, over temperature protection and other functions, when the grid parameter exceeds the set limit, the capacitor can be quickly removed to protect the safe operation of the circuit and extend the service life;
Multipoint sampling technique
Using MCU microelectronic control circuit technology, multi-point sampling of voltage, current, power, power factor and other data is used to determine the trend of reactive power flow, avoiding the misjudgment of single point sampling and accurately determining the required reactive power and compensation direction (switching on or off);
Encoding cycle switching
Adopt the coding cycle mode, the same capacity in order to cycle switching, capacity of different coding according to the requirements, and then dynamic adaptation compensation, effectively improve the compensation accuracy, with less action times to obtain the best compensation effect;
Manual/automatic switching function
When the automatic function is set, the input or removal of capacitors can be controlled according to the comprehensive factors of voltage, load, power factor and reactive power deficiency. It can also manually operate the input or removal of the capacitor, which is convenient for factory debugging and quick switching of the capacitor.
Communication control function
The use of network line 485 communication control protocol, easy to install and use, fast communication rate.
