The following symbols have been used in this manual. This symbol gives information regarding points important for user’s own health and safety, AVR operation and the safety of your data. This symbol gives information, warnings, and other suggestions. This symbol shows the operations that need to be executed. -
Page 6: 4- Introduction
4- Introduction Input power is applied across the motor driven variable transformer which has a “center tap” that divides the variable transformer into bucking and boosting voltage areas.The buck-boost transformer is a fixed ratio isolation transformer capable of high amperes at low voltage. The ratio of the buck-boost transformer is determined by the amount of voltage needed to buck or boost the input line voltage to maintain the specified output level. -
