How much does a vehicle voltage booster 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   vehicle voltage booster 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 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.

Remote control switch circuit
The remote control switch operation of the module power supply is carried out through the REM terminal. There are two general control methods:
(1) REM is connected to -VIN (reference ground), the remote control is turned off, and VREF<0.4V is required. REM is suspended or connected to +VIN, the module works, and VREM>1V is required.
(2) REM is connected to VIN, the remote control is turned off, and VREM<0.4V is required. REM is connected to +VIN, the module works, VREM>1V is required. REM is suspended, and the remote control is turned off, that is, the so-called "suspended shutdown" (-R).
If the control is to be isolated from the input, an optocoupler can be used to pass the control signal

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 voltage power supply. Ordinary home circuits or enterprise circuits can use ordinary wide range input Marine boost voltage power supply module supplies!

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