The power distribution unit (PDU) is a critical component of a system, responsible for efficiently managing and distributing electrical power to various subsystems and components. The PDU regulates and conditions electrical power from the main power source to ensure it meets the requirements of the system. It converts and adjusts the voltage, frequency, and waveform to match the needs of different components and ensures that each component receives the required power level without overloading the system.

It provides protection mechanisms, such as circuit breakers, to isolate faulty components and prevent damage to the system. PDUs must adhere to EMC standards to prevent interference with other electronic systems on the platform and should be designed to withstand harsh environmental conditions, including temperature variations, vibration, shock, and moisture
