As we all know, the car jump starter of multi-function automobile belongs to a kind of electronic equipment, so it should adopt a number of global patent safety protection design, such as anti-charge protection function, overvoltage protection function, over-current protection function, polarity reverse protection power, output short circuit protection function, operation no A number of functions such as spark safety. Of course, as a mobile power supply, the most important of the car emergency start power is overcurrent protection. Today, we will explain what is the over-current protection of the car jump starter.

In a large number of electronic equipment products, there will be a rated current, and the automobile emergency power supply is no exception. At this time, the over-current protection in the car emergency power supply has a role to play. Overcurrent protection, when the current exceeds the predetermined or the maximum set value, is intelligent to automatically break the equipment, and then to achieve a protective device protection mode. Therefore, if the overcurrent protection function in the car jump starter has overcurrent protection function, the protection device will start automatically when the current over the protected original exceeds a predetermined value, and the time limit is used to ensure the selectivity of the action, so the circuit breaker is tripped or the alarm signal is given.

This kind of overcurrent protection is divided into two main categories, one is short-circuited protection, the other is overload protection. The characteristic of short circuit protection is to set large current and instantaneous action, and the characteristic of overload protection is to set small current and reverse time. But no matter what type of protection is a kind of overcurrent protection, it can play a protective role for its current.

In addition, it is also necessary to pay attention to the connection mode of overcurrent protection in the best car jump starter, because only the correct selection of the connection mode of overcurrent protection will have a great influence on the protection technology and economic performance. Otherwise, the improper selection of the overcurrent protection connection mode is not particularly significant for the protection of its technical and economic performance.
