The communication initial power distribution unit is used for the initial power distribution of the model AC distribution system. It completes the intelligent distribution and management of power by receiving bus control instructions or switch quantity instructions from the upper computer. It has functions such as switch status feedback, current, voltage, and frequency parameter feedback, overcurrent and short-circuit protection, overvoltage protection, undervoltage protection, leakage protection, and phase loss protection. 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.
