How much does a vehicle converter cost?(2)
Due to the wide variety of integrated circuits used in communication equipment, their power supply voltages are also different. In the communication power supply system, a high-frequency DC-DC isolation module power supply with high power density is used, which is converted from the intermediate bus voltage (usually 48V DC) to Various DC voltages are required, which can greatly reduce losses, facilitate maintenance, and are very convenient to install and increase. Generally, it can be directly installed on the standard control board, and the requirement for the secondary power supply is high power density. Due to the continuous increase of communication capacity, the capacity of communication power supply will also continue to increase.
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 LED advertising screen 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 LED advertising screen power supply. Ordinary home circuits or enterprise circuits can use ordinary supplier supplies!
In addition, the situation in the current market is also very different. The price of the vehicle converter 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.
