Introduction to reactor and voltage regulator
Leilang-Electric is located in Shanghai,China.We are specialized in manufacturing all kind of low voltage transformer,three phase transformer,single phase transformer, variac transformer,voltage stabilizer, ac stabilizer,power regulator, reactor, etc.
Product overview: DBW, SBW series single and three-phase fully automatic compensated power regulators are a kind of energy-saving high-power AC stabilized power supply designed by our company according to the national conditions of our country with the introduction of international AC stabilized power technology. It can automatically keep the output voltage stable when the voltage of external power supply network fluctuates or the load changes.
Compared with other types of voltage regulators, this series of products have the advantages of large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc. they are suitable for a wide range of loads, can withstand instantaneous overload, can work continuously for a long time, manual / automatic switching, with over-voltage protection, phase loss protection, phase sequence protection and mechanical failure automatic protection. This machine has reliable operation, small volume, light weight, etc Easy to use and install. (score display and instrument indication)
