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


power supply module

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 Marine boost/buck voltage 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 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.

HVDC module power supply
High-power switching high-voltage DC power supplies are widely used in large-scale equipment such as electrostatic dust removal, water quality improvement, medical X-ray machines and CT machines. The voltage is as high as 50~159kV, the current reaches more than 0.5A, and the power can reach 100kW.
Since the 1970s, some Japanese companies have begun to use inverter technology to rectify the mains and invert it to an intermediate frequency of about 3kHz, and then boost it. In the 1980s, high-frequency switching power supply technology developed rapidly. Siemens of Germany uses power transistors as the main switching elements to increase the switching frequency of the power supply to above 20kHz. And the dry-type transformer technology is successfully applied to the high-frequency high-voltage power supply, the high-voltage transformer oil tank is cancelled, and the volume of the transformer system is further reduced.

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 manufacturer supplies!

In addition, the situation in the current market is also very different. The price of the   vehicle voltage booster/buck Marine boost/buck voltage 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.
