How much does a vehicle converter cost?(1)

(9) For the high-voltage module power supply, do not touch the high-voltage dangerous area during use and within 10 minutes after the power outage.
(10) Purchasing principle of module power supply: Generally, switching power supply should be selected for larger power, and linear power supply should be selected for smaller power.
(11) The module power supply cannot be forcibly dismantled, and it will be damaged if it is forcibly dismantled.

Now if you go to search for vehicle converter, you will find that the price difference is very big. The cheap ones are more than ten yuan, and the more expensive ones are more than 1,000 yuan. Why is the price difference between the cheap and the expensive so big? What are the main differences?

There is a big difference in price between cheap and expensive. In fact, this is mainly because it is used in different occasions. Thousands of dollars are generally used in vehicle converter systems. This kind of power module has high requirements on performance, parameters, life and other aspects, and the price will be more expensive, and this kind of power module is a high-frequency voltage switching Marine boost power supply with multiple independent outputs, which is very important to the production process, etc. The requirements in all aspects are also relatively high, so this will be more expensive.
