How much does a boost/buck voltage power supply for vehicle air conditioning cost?(2)
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.
It's not that expensive is good! But it depends on the specific use occasion. Only high-voltage occasions are recommended to use this Marine boost/buck voltage power supply. Ordinary home circuits or enterprise circuits can use ordinary wide range input Marine boost/buck voltage power supply module supplies!
Internationally, the inverter power supply series products below 400kVA have come out. In the early 1980s, Toshiba Corporation of Japan was the first to apply AC variable frequency speed regulation technology to air conditioners. By 1997, its share had reached more than 70% of Japan's household air conditioners. Inverter air conditioners have the advantages of comfort and energy saving. In the early 1990s, domestic research on inverter air conditioners began. In 1996, the production line was introduced to produce inverter air conditioners, which gradually formed a hot spot for inverter air conditioner development and production. A climax is expected around 2000. In addition to the variable frequency power supply, the inverter air conditioner also requires a compressor motor suitable for variable frequency speed regulation. Optimizing the control strategy and selecting functional components are the further development direction of the inverter power supply for air conditioners.
In addition, the situation in the current market is also very different. The price of the boost/buck voltage Marine boost/buck voltage 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.
