The table below gives approximate quantitative advantages of automatic voltage controller at various fluctuation levels: Comparison between GTB make and Conventional make automatic voltage controller: GTB make Roller Type Regulator: Power consumption is 0.5 to 1.5% depending upon the model input voltage variation. Suitable for continuous 100% duty cycle. Life at full load is 15-20 years. Five years unconditional guarantee. Negligible losses in full boost buck condition. Conventional make with Carbon Brush Regulator: Power consumption is 2 to 7% depending upon the model input voltage variation. Suitable for only 30% to 40% duty cycle. Maximum life is 2-3 years at full load. Normal guarantee for one year. Max. Losses in full boost and buck condition.
