How much does a boost/buck voltage power supply for vehicle air conditioning cost?(2)
Green module power
The rapid development of computer technology has led human beings into the information society, and also promoted the rapid development of module power technology. In the 1980s, computers fully adopted switching power supplies, taking the lead in completing the replacement of computer power supplies. Then switching power supply technology has entered the field of electronics and electrical equipment one after another. With the development of computer technology, green computer and green module power supply are proposed. Green computers generally refer to personal computers and related products that are harmless to the environment. Green power refers to high-efficiency power-saving power sources related to green computers. According to the "Energy Star" plan of the United States Environmental Protection Agency on June 17, 1992 If the power consumption of a small personal computer or related peripheral equipment in the sleep state is less than 30 watts, it meets the requirements of a green computer. Improving power efficiency is the fundamental way to reduce power consumption. For a 200-watt switching power supply with an efficiency of 75%, the power supply itself consumes 50 watts of energy.
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 24V input 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 24V input 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.
It's not that expensive is good! But it depends on the specific use occasion. Only high-voltage occasions are recommended to use this 24V input power supply. Ordinary home circuits or enterprise circuits can use ordinary dc switching 24V input power supply supplies!
In addition, the situation in the current market is also very different. The price of the boost/buck voltage 24V input power supply for vehicle air conditioning fluctuated to a certain extent. If you search online, you will find cheaper ones that cost more than ten yuan, but it is not recommended to choose this kind of excessive Inexpensive power modules, because the overall quality of this product is difficult to say, it is recommended that you choose tens of dollars, or 200-300 dollars. This kind of comprehensive technology and various aspects will also be better, so When purchasing, you should also look at the certification of the manufacturer. If a manufacturer's qualifications meet the requirements in all aspects, continue to choose. If the requirements are not met, do not blindly buy a power module.
