How much does a vehicle voltage booster/buck power supply module cost?(2)


module power supply

(DC/DC) converter
The DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in the stepless speed change and control of trolleybuses, subway trains, and electric vehicles. Responsive performance, and at the same time receive the effect of saving power. Replacing the varistor with a DC chopper can save power by (20~30)%. The DC chopper can not only play the role of voltage regulation (switching power supply), but also can effectively suppress the harmonic current noise on the grid side.

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 voltage booster/buck LED advertising screen power supply module 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 vehicle module LED advertising screen power supply supplies!

In addition, the situation in the current market is also very different. The price of the   vehicle voltage booster/buck LED advertising screen power supply module 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.
