Key Features

♦ Using intelligent controller control, complete functions, reliable performance, automatic compensation method: the power factor can be increased to more than 0.9:

♦ Real-time display of grid power factor, display range: lag (0.00-0.99), lead (0.00-0.99):

with overvoltage, harmonic, compensation, system failure, lack of phase, overload and other comprehensive protection functions;

♦ Memorize the set parameters, the system will not lose the parameters after power failure, and the power grid will automatically enter the running state after returning to normal, without personnel on duty:

♦ According to the power grid load balance situation, take separate phase compensation or mixed compensation;

♦ Strong anti-interference ability, can resist the amplitude of 2000V interference pulse directly input from the power grid, which is higher than the national professional standard.
