SBW-F series of automatic compensation regulator (hereinafter referred to as the regulator), is my company to introduce and absorb advanced technology in Western Europe, combined with China's national conditions, designed to stabilize the AC voltage. It consists of contact voltage regulator, compensation transformers, automatic control circuit and servo motor. Compensation transformer is the second string in the main loop, once connected to the contact with the regulator's output. When the grid voltage instability or load changes, is given by the automatic control circuit from the voltage regulator output sampling control signal, and control of contact voltage regulator, servo motor rotation in contact with carbon brushes by the chain drive reduction gear reducer regulator surface for reciprocating slide to adjust the exposure to the regulator output voltage to change the compensation transformer secondary voltage automatically to maintain the stability of the output voltage can be achieved.
This series regulator can be used for all the needs of the regulator of occasions. Such as factories, mines, enterprises, oil fields, railways, hospitals, post and telecommunications, hotels, construction, research and other departments of machining equipment, textile machinery, automatic production lines, test equipment, elevators, medical equipment, computer room, central air conditioning, cranes, mixers, printing equipment and so on.

Regulator of this series has the following characteristics:
· High efficiency (98%);
Does not produce waveform distortion;
· The voltage regulator is stable;
Applies to any load (resistive, capacitive, inductive load);
Able to withstand transient overload;
Can be long-term continuous work;
With regulation, electricity two independent power supply system;
· Regulator status of the two control modes, and manual / automatic control switch easy to operate.
Main technical parameters:
· Input voltage range: line voltage 380V ± 30%
· Output voltage: Line voltage 380V (1 ± 5%) can be set
