   function 
Control signal: comprehensive control by using the power factor and reactive current of two physical quantities;
Step :step number selected by the user;
Data storage: after the loss of electricity parameter settings will not be lost, data save permanently;
Adaptability: automatically adapt to the distribution system of different parameters of the controller, does not need to provide the transformation ratio of current transformer and capacitor compensation capacity;
Overvoltage protection: the voltage is higher than the set value quickly over voltage, gradual resection capacitors have been put;
Strong antiinterference: unique design, crash, indiscriminately, indiscriminate cutting phenomenon can not occur in operationSwitching shocks: can prevent the small current load and over voltage critical values appear repeated switching;
High sensitivity: compensator can work normally in the input signal when the current is 0.10A;
Display error: input signal power of current 0.10A to 5A changes due tonumerical error measurement showed minimal;
The current identification: the controller can judge the sampling current polarity and automatic conversion.
