Wholesale autotransformer from China is a transformer whose windings are primary and secondary on the same winding.
Features of Wholesale autotransformer from China:
1. Structure
The primary side and the secondary side of the Wholesale autotransformer from China have a direct electrical connection. Its low-voltage coil is a part of the high-voltage coil, that is, a winding with only one electrical path. There is a tap in the middle of the winding as the common point of the high-voltage and low-voltage coils.

2. Safety factor
Because the high and low voltage coils of the Wholesale autotransformer from China have overlapping parts, part of the coil wire material is saved, which is not only small in size but also low in cost. However, its high and low voltage coils are connected. Even if the output voltage of the low voltage side of the step-down transformer is very low, because the two windings share a common part, the high voltage of the primary will also "slip into" the coil of the secondary, which is very easy to cause damage to people. harm.
3. Use
The primary side and the secondary side of the Wholesale autotransformer from China have direct electrical connection. If the line is damaged and leakage, it is very easy to cause harm to people. Generally used in places with low safety requirements, only need to change the voltage to make the voltage meet the required voltage of the equipment, but the equipment cannot be equipped with leakage protection devices, and the zero line cannot be grounded.
