Laboratory autotransformer - a device that regulates the current and voltage in a wide range with a smooth change in performance. The process is provided by moving the movable contact along the turns, changing the induction in the winding. The device allows to form at the output the exact voltage values and a pure sine wave. The design has a high efficiency, up to 98%, has a smaller size and weight, compared with analogues. The autotransformer is used in country and garden plots with a reduced value of input voltage. Used in laboratories, workshops, for charging batteries, power consumers with non-standard values of voltage.
