DPR, SPR singel three phases AC voltage stabilizer, voltage regulator, AVR is a contact adjustable automatic voltage compensation high power requlating power device. When voltage from suppht network is varied o due to loading current effect, it automatically regulates the output voltage to ensure the nomal function of the varied of electric equipments.

USE SITUATION
Widely used in post and telecommunications, department stores, elevators, hospitals, schools, printing, securities and other occasions where all needs normal voltage to ensure, such as workshop mines medium enterprises, some of the important equipment and computer power and support.
