I、SBW and DBW series of three phases and single phase automatic complementary electrical power voltage regulator
1、Summary

The SBW and DBW series of complementary AC electrical power voltage regulator (hereafter referred to as the voltage regulator) is designed by our factory with the imported and absorbed European advanced technology, according to the conditions in China, for the AC voltage regulation. It can automatically maintain the stability of the output voltage when the voltage supplied by the external supplying network fluctuates or the voltage fluctuates caused by the load varies.
     This series of products have high capacity, high efficiency, without waveform distortion, stable voltage regulation compared with other kinds of voltage regulators and suitable for broad load range, and able to bear instant over load. It can run continuously for a long time, with free manual control switching and automatic protection device of over voltage, over current, failure of phase sequence and mechanism. It also featares small size, light weight, easy to install and use, and runs stably.

Main features: high efficiency, low consumption, small waveform distortion, short strain time, reliable operation, wide range, and high accuracy.

Applicable scope: Large mechanical and electrical equipment, metal process equipment, production flow line, construction engineering equipment, elevator, medical appliance, computer room and computer controlled equipment, embroidery and textile equipment, air conditioner, electrical appliance of broadcasting and TV, hotel, and household in the industry, agriculture, traffic, post and communications, military, railway, scientific and research and culture field, where voltage regulation is needed

2、Main technical index and specifications

1、Efficiency: ≥98%
2、Insulation resistance: ≥2MΩ
3、Waveform distortion: ≤0.1%
4、Operation frequency: 50~60Hz
5、Accuracy of voltage regulation: ±(1 to 5)%, settable
6、Stabilizing time: the stabilizing time is smaller than 1.5s when the input voltage phase
     transition to rated value occurs at 10%
7、Voltage resistance: three phases: 2000V, without breakdown for one minute; single
     phase: 1500V, without breakdown for one minute
