Linear Voltage regulators employ vertical windings with Carbon Rollers on both sides of the coil. Linear technology employs heavy section of electrolytic grade rectangular Copper Strip, in order to minimize the losses. The core is built from grain oriented silicon steel laminations to keep the losses to the minimum. This is suitable for 100% continuous duty & have the capability to adhere to heavy inrush starting Loads.The Roller brush technology gives high reliability due to less wear & tear, as the surface area in contact keeps on changing during the stabilization process. The roller contact is fitted with spring tension behind to keep the roller intact with coil for trouble free operation. There are self lubricationg roller assemblies with a life span of appx. 1 lac track meters.

The control circuit continuously monitors the output voltage and looks for any error in the output. Any deviation in the output is immediately corrected by switching on the Servomotor. The motor coupled to the variable auto transformer increases / decreases the voltage to primary of buck / boost transformer. The buck / boost transformer adds / substracts the voltage to mains so that the output remains within the set limits.
