The three-phase load imbalance automatic regulation device (NADSPC) is mainly used on the low-voltage distribution user side to control three-phase current imbalance, low phase voltage, and compensate for reactive power, optimizing power quality. NADSPC product specifications cover 50A/35kvar, 75A/50kvar, 150A/100kvar, and can simultaneously compensate for three-phase unbalanced current and reactive power, achieving continuous and dynamic compensation.
