2. Main Components

① Pure copper transformer: the transformer is made of copper, which increases the electricity inductiveness and strengthens the voltage compensation functions.

② Pure copper column: the copper column major functions in regulating voltage automatically.

③ 1017 Carbon brush: this part moves along the copper colum, thus realizing voltage regulation.

④ Circuit board: the circuit board gives out signals to servo motor, which drives the chain to move.

⑤ Servo motor: driving the chain, together with carbon brush, to move up and down.

⑥ AC contactor: protecting the voltage stabilizer.

⑦ Iron enclosure: protecting the whole parts of this product.

⑧ Pointer meters: displaying data clearly.

⑨ Chain drive: moving together with carbon brush, thus realizing voltage regulation.
