ST step-up down transformer is an AC voltage converting device.Using it is to convert the multi-kind net voltages into a general output voltage under which all the electroelectronic units are safe for use within the rated power range. Input voltage:AC110V or 220V or 220V or 240V With fuse protector or with over current protector Output voltage:AC110V and 220V
