Description
JKCS-0.48-20KVAR-3 Intelligent Harmonic Power Capacitor 
The intelligent capacitor are modular in design, consists of intelligent measurement and control unit(s), zero-crossing switching circuit, line protective unit(s) and low-voltage power capacitor(s).It adopts the upper-and-lower split type modular structure, and the upper part consists of intelligent measurement and control unit(s), switch unit(s) and protective unit(s), while the lower part consists of two ( △ type) or one (Y type) low-voltage power capacitor. There is three-phase compensation and single-phase compensation, thus the product can be used alone or in the compensation system consisting of more products
