With RS485 interface, it can control SVG and smart capacitors at the same time;
It can monitor the switching status of SVG and capacitors;
High detection accuracy, electrical parameter accuracy is not more than 1%;
Complete functions, with overvoltage and undervoltage protection, harmonic voltage protection and other functions;
The capacitor control scheme supports three-phase common compensation, sub-compensation, hybrid compensation, etc., which can be selected through parameter settings;
Supports cyclic switching for equal-capacity capacitors, and preferential switching for unequal-capacity capacitors;
It has two working modes of automatic/manual compensation;
Strong redundancy, when the SVG fails, the switching of the capacitor can still be controlled.
12 groups of dry contact control signals;
2 groups of temperature detection and protection;
3 groups of switch signal input;
4 groups of switch signal output;
1 channel RS485 communication.
