Power management / distribution units (PPDU, SPDU)

Introduction to PPDU & SPDU

Power Management Units (PPDU) and Power Distribution Units (SPDU) are critical infrastructures in modern electrical and electronic systems. PPDU focuses on monitoring and regulating power supply operations, ensuring stability, efficiency, and protection. SPDU focuses on distribution, splitting the total power source into multiple channels to provide independent supply interfaces for downstream devices such as servers, switches, automotive electronics, and aerospace equipment.

Core Functions

PPDU – Real-time monitoring of voltage/current, overvoltage and overload protection, intelligent regulation of power output, and ensuring efficient energy use.
SPDU – Dividing power into multiple independent channels, improving redundancy and flexibility, supporting multiple loads simultaneously.

Application Scenarios

Data Centers – PPDU ensures stable supply to servers, while SPDU distributes power across multiple racks.
Automotive Electronics – Vehicle electronic control systems require precise power management and multi-path distribution.
Aerospace & Satellites – Space missions demand lightweight, high-reliability PPDU/SPDU modules for energy allocation to subsystems.
Industrial Automation – Supporting robotics, production lines, and sensitive measurement equipment with reliable energy control.
