Contact Voltage Regulator

Share  | 

Contact voltage regulator is a special type of voltage regulator that maintains a constant voltage level in various electrical and electronic equipments. These devices have a specific mode of operation.

Working Principle
The device has a coil, which rotates on the loop core along with three brushes colliding with the surface in contact with the coil. This is accomplished with the help of a spring pressure effect. The coil rotates the revolving shaft to activate the brush stand. This results in rotation of the brush along the coil surface to change the contact position of the brush. Altering the turning rate of coil leads to accurate adjustment of the output voltage within a specific range.
