Three phase high power power voltage regulator SBW-50KVA Full automatic compensated voltage regulator SBW-80KVA Item NO.: 1950487

1. Overview (dbw.sbw single and three-phase fully automatic compensated power regulator)

SBW and DBW series single / three-phase fully automatic compensated power regulators are voltage regulators designed by our company to stabilize AC voltage by introducing and absorbing advanced technology from Western Europe and combining with China's national conditions. When voltage fluctuation is caused by voltage fluctuation of external power supply network or load change, the voltage regulator (regulated power supply) can automatically maintain the stability of output voltage. Compared with other types of voltage regulators, the voltage regulator (regulated power supply) has the advantages of large capacity, high efficiency, no wave opening distortion, voltage regulation and balance. The voltage regulator (regulated power supply) is suitable for a wide range of loads and can overload with instantaneous. The voltage regulator (regulated power supply) can work continuously for a long time and switch manually / automatically at will. The voltage regulator (regulated power supply) is equipped with overvoltage, overcurrent, phase loss The utility model has the advantages of small volume, light weight, convenient use and installation, reliable operation, etc.

2. Application occasion (dbw.sbw single-phase and three-phase fully automatic compensated power regulator)

Shanghai NUOJIAN voltage regulator (regulated power supply) is widely used in Large-scale Electromechanical equipment, metal processing equipment, production lines, construction engineering equipment, elevators, medical devices, embroidery and textile equipment, air conditioning, radio and television, household electricity and lighting in the fields of industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and culture. SBW and DBW series voltage regulators shall be used indoors. The normal service conditions of the voltage regulator (regulated power supply) are:
