It is a device which corrects the heavy fluctuating raw incoming power supply and provides constant stabilized voltage to equipments to the accuracy of 0.5 to 1.0 % raw power is fluctuating in nature and, may therefore cause severe damage to the expensive hi-tech electrical electronic equipments, if not controlled & stabilized. Besides the risk of damage, it can consume more power leading to higher electricity bills. Therefore it is necessary to control & stabilize the raw power.
