How much does a boost/buck voltage power supply for vehicle air conditioning cost?(1)

Distributed Power Supply System
The distributed power supply system uses low-power modules and large-scale control integrated circuits as basic components, and uses the latest theoretical and technological achievements to form a building block-type, intelligent high-power power supply, so that the strong and weak currents are closely combined and the high power is reduced. Components, high-power devices (centralized) development pressure, improve production efficiency.

Now if you go to search for boost/buck voltage Marine boost/buck voltage power supply for vehicle air conditioning, 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   boost/buck voltage Marine boost/buck voltage power supply for vehicle air conditioning 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/buck voltage 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.
