Isolation transformer is the device which transform alternating current (AC) electrical power from primary to secondary side, makes it ideal for use in the electrical and the engineering industries. The AC power supply voltage we usually use is connected to the ground with one wire, and there is a potential difference of 220V between the other wire and the ground. If human contact it, it can cause electric shock. The secondary winding of the isolation transformer is not connected to the ground, and there is no potential difference between any two lines of it and the ground. People will not get electric shock when they touch any line, so it is safer.

The output end of the step up & step down isolation transformer is completely "open circuit" isolated from the input end, which effectively plays a good filtering role on the input end of the transformer (power supply voltage supplied by the grid). Thus, a pure power supply voltage is provided to the electrical equipment. Isolation transformers are safe power supplies, generally used for machine repair and maintenance, and play the role of protection, lightning protection, and filtering.
