Type: (W) K series single, three-phase non-contact compensated microcomputer power regulator 
 Specifications: Single phase: 5kVA ~ 500kVA 
 Three Phase: 10kVA ~ 1500kVA 
 Quality: (special specifications, separate design) 
 Product Description: DBW, SBW series of single, three-phase non-contact compensated microcomputer power regulator (hereinafter referred to as regulators), is the introduction of the international exchange of power supply the latest technology and designed according to China's national conditions and the exchange of a new high-power power supply. It combines a combination of advanced methods and compensation winding non-contact switch, computer control technology in one exchange regulator, with energy-efficient, quick adjustment, three phase automatic balanced no mechanical failure and carbon brush wear, and have the delay, too, under-voltage alarm and protection. The regulator also a breakthrough to solve the system and devices running on the non-contact switching transient process produced by common mode current impact and damage caused by over-voltage, high instantaneous overload capacity, thus greatly improving the system reliability .
