Product Details

1 product introduction
SBW series compensation type automatic AC voltage regulator is divided into single-phase DBW and three-phase SBW， two types,Compared with other forms of voltage regulator, it has the advantages of large capacity, high efficiency, stable voltage regulation. Suitable for a wide range of load, can withstand instantaneous overload, can be a long-term continuous voltage regulator, with over voltage, short circuit protection function, the use of convenient installation, reliable operation and so on. Can be widely used in industry, agriculture, transportation, telecommunications, railways, military, cultural and other fields of scientific research of large mechanical and electrical equipment, metal processing equipment, production lines, construction equipment, elevator, medical equipment, computer room, computer control embroidery equipment, textile equipment, air conditioning, TV, hotel and household appliances lighting etc. where need the regulator.Meet the standards: JB/T 8449, Q/ZT 431.
