This step-up and down transformer is an ac voltage converting device. Using it to convert the multi-kind net voltage into general output under which all the electronic equipment are in safe operation.This step up and down transformer can convert 110v to 220v and vice versa. It has a capacity of 200va. It has precise input voltage selector which you can select(110volts or 220volts depending on the voltage source available)via selector switch located at the back of the unit.
Output voltage is 110volts and 220volts that can be used at the same time. Suitable for television, computer, rice cooker, mini home theater, electric fan, printer. It has an input voltage of ac 110v or 220v and an output voltage of ac 220v or 110v
