Power Distribution Units (PDUs) serve as the backbone of electrical management in a wide range of applications — from high-voltage battery systems in electric vehicles (EVs) and commercial energy storage systems (ESS) to rack-mounted power management in data centers and server rooms. A well-designed PDU ensures stable power allocation, circuit protection, and in many modern configurations, real-time monitoring and remote management.
China has developed a robust PDU manufacturing industry over the past two decades, with suppliers ranging from specialists in high-voltage DC devices for new energy applications to broad-based manufacturers serving global data center markets. The companies listed below represent a cross-section of that ecosystem, ordered roughly by scale of influence and market reach.
