Red led flash to indicate the load exceed the current limit and the protecting function start 红灯闪烁,表示过负载,使用电流超过额定设定,主机保护机制开启。
It also includes thermal protection and current limit , protecting the load and the regulator during fault conditions 具有热保护和电流限制功能,保护工作在不正常条件下的负载元件和芯片。
Based on this background , the author does some research on engineering application of the solid states fault current limiting technology 本文是在已有工作的基础上,对固态短路限流技术进行工程化研究。
Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current that may be delivered to a load with the purpose of protecting the circuit generating or transmitting the current from harmful effects due to a short-circuit or similar problem in the load. This term is also used to describe the ability of an overcurrent protective device (fuse or circuit breaker) to reduce the peak current in a circuit, by opening and clearing the fault in a sub-cycle time frame.
