Principle & Characteristics
The voltage regulator is in the structure of adjustable compensator, it winds a coil on the loop core, thee brush coincide with the rubbed surface of the coil closely under the spring pressure effect, rotate the revolving shaft to drive the brush stand, and make the brush move along the coil surf ace to change the contact position of the brush, that means change the turns rate of primary and secondary coil, which can make the output voltage stepless adjusted within the adjustment range. It has the advantage of no waveform distortion, small volume, less weight, high efficiency, simple and reliable operation, un for long period and so on.
Scope of Application
It is widely used in industry (as chemical industry, metallurgy, instruments, meters, electromechanical manufacturing, light industry etc.), scientific experiment, public facilities, and domestic electric appliance to fulfill voltage regulating, temperature control, speed regulating, light adjusting, power control and so on, it is an ideal AC regulated power sour
