Changes brought by the power distribution technology based on semiconductor devices, more functions A single HSD chip can replace 1 fuse and 1 relay, at the same time realize controllable switch and line protection and diagnosis functions, and have more functions, smarter, more Reliable, smaller and lighter. HSD chip = relay + fuse The following table is a comparison of specific functions: Function comparison Powerful protection functions and diagnostic functions are the basis of reliability and intelligence. From the performance comparison, we can see that smart power distribution boxes based on semiconductor devices, whether they are From the service life, the difficulty of use, the temperature range, the application range, the switching speed, the protection speed, etc., its performance is completely crushed by the traditional power distribution box. This is the crushing of traditional electromechanical technology by electronic technology, and the crushing of the industrial age by the era of intelligent networking.
