Introduction of 12V Transformer:

It is a device that uses the principle of electromagnetic induction to change the AC voltage. 12V Transformer belongs to a category of transformers, and its functions are voltage conversion, current conversion, impedance conversion, etc.

How the Direct plug transformer works:

The working principle of the direct plug transformer is similar to that of a switching power supply. VD1~VD4 converts the mains into DC, and then converts the DC into a high-frequency current of tens of kilohertz, and then uses a ferrite transformer to step down the high-frequency and high-voltage pulses. R2, C1, VD5 are the start trigger circuit. C2, C3, L1, L2, L3, VT1, VT2 constitute the high frequency oscillation part. When the 12v transformer is working normally, the working voltage of point A is about 215V, point B is about 108V, point C is about 10V, and point D is about 25V. If it does not oscillate, check whether the phases of VT1, VT2 and L1, L2, L3 are normal. Changing the number of turns of L5 can change the output high-frequency voltage.

Product features of 12V Transformer:

1. 12V Transformer overcomes the shortcomings of traditional silicon steel sheet transformers such as large volume, weight and high price, and has stable performance.

2. The rated voltage of 12V Transformer refers to the voltage allowed to be applied on the coil of the transformer, and it shall not be greater than the specified value during operation.

3. The 12V Transformer transmits AC and isolates DC, and can realize voltage conversion, impedance conversion and phase conversion at the same time.
