The DC primary power distribution unit is used for the initial power distribution of the model DC distribution system. It completes intelligent power distribution and management by receiving bus control instructions or switch commands from the upper computer. It 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. Main performance indicators:
