LOSG Autotransformer

LOSG autotransformer is a kind of single-loop transformer, which is suitable for the place where the voltage needs to be changed and there is no requirement of safety isolation. It has many advantages, such as small volume, light weight, relatively low cost, etc. . It is widely used in power supply, lighting, control and other scenarios.

  • Product Description
  • Product parameters
  • A Autotransformer is a transformer whose primary and secondary windings are on the same winding. The primary and secondary windings are directly connected in series and are self-coupled. According to the structure can also be subdivided into adjustable pressure and fixed type. Self-coupling means electromagnetic coupling. Ordinary transformers transmit energy through electromagnetic coupling of the primary secondary side coils. The primary side has no direct electrical connection, while the primary side has a direct electrical connection, and the primary side of the Autotransformer has a direct electrical connection, its low-voltage coil is part of the high-voltage coil. The Autotransformer is based on a self-induced phenomenon in the electromagnetic induction that regulates the voltage level. Protective devices such as Autotransformer are also used in communication lines.

     

    Product Advantage:

    1. The size of the Autotransformer for a transformer ratio = 2 is about 50% of the corresponding size of the two-winding transformers. For conversion, assume 20, but the size will be 95% . The cost of materials is certainly not a percentage. When the ratio of transformer is lower than 2, the cost saving is considerable. As a result, Autotransformer are smaller and cheaper.

    2. The Autotransformer transformer is more efficient than the double-winding transformer. This is because the reduction of transformer material results in smaller ohm loss and core loss.

    3. The Autotransformer has better voltage regulation because the resistance and reactance of a single winding have smaller voltage drops.”
