Systemprinciple:
Transformer is the use of electromagnetic induction principle, so as to achievethe change in the AC voltage device.

The product isdeveloped according to the latest CNC servo system parameters.
The basic function of the conventional transformer is to change the voltageinput to the output voltage, so that different countries in the world betweenthe voltage of the equipment, through the small transformer voltage conversionto all countries can match the purpose of the general purpose. The maincomponents are primary coil, secondary coil and core (silicon steel). Inelectrical equipment and wireless circuits, commonly used for lifting voltage,matching impedance, safety isolation. Transformer is a static electromagneticdevice, the transformer can be a voltage of AC power into the same frequency ofanother voltage AC power, the transformer is the main component of an iron coreand set in the core of two or more lines group. The transformer is connected tothe input power supply coil, receiving AC power, called the primary line orprimary, in the load connected coil, send AC power, known as the secondary linegroup or secondary.
