The DC secondary power distribution unit is used for the distribution of secondary power in model DC distribution systems. It intelligently distributes and manages power by receiving bus control instructions or switch commands from the upper computer. Solid state power controller (SSPC) is used as the distribution output, which has functions such as switch status feedback, current and voltage parameter feedback, overcurrent protection, overvoltage and undervoltage protection, overheating protection, etc. At the same time, it has high reliability and safety indicators, good electromagnetic compatibility and environmental adaptability, small size, light weight, low power consumption, and easy maintenance.
