How much does a vehicle voltage booster/buck power supply module cost?(3)

(6) For the module power supply, some manufacturers have a fixed resistance directly connected to the adjustable terminal (ADJ) from the factory. When using, the user must configure a potentiometer with the corresponding resistance value to replace the fixed resistance. However, it should be noted that when the adjustable terminals are in an open state, loading is never allowed.
(7) In order to achieve sufficient heat dissipation, the module power supply should be installed in a location with better air convection. Generally, when the working current of the linear power supply is above 4A, or the working current of the switching power supply is above 7A, forced air cooling should be installed. In addition, no other items are allowed on the module power supply housing.
(8) The module power supply is generally suitable for resistive-based loads. If it needs to be applied to capacitive-based or inductive-based loads, it should be explained in the order contract in advance and customized by the manufacturer.

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