Profile
Series of reactive power automatic compensation controller, with high speed and high performance microprocessor as the core device also sampling three-phase voltage and three-phase current signal and provide six separate compensation is compensation scheme, 12 kinds of switching coding scheme, the user through the modification of control parameters of arbitrary choice, control parameters modified permanent preservation, power down fill missing. The fundamental power factor and the fundamental group of power compound control capacitor switching, switching stability without switching shocks, for voltage harmonic interference complementary sensitivity. In exchange 45Hz-65Hz and 0.4kV power system following the non automatic control of reactive power compensation.
