The fixed step-up & step-down transformer is an ideal step-up & step-down power. It can, effectively, have the voltage drop from 200V to 110V or climb from 110V to 220V, with the wave not distorted. It possesses a beautiful outline and a rather long operating life, and also can be operated easily. With such stated characteristics, it is suitable for imported electric devices.
