Power Distribution Unit (PDU)
Definition
A Power Distribution Unit (PDU) is an electrical distribution device used in data centers to deliver and manage power from the facility electrical system to individual IT equipment racks.
PDUs provide safe, reliable, and organized power distribution within data center environments.
Why It Matters
As data center rack densities increase, especially in AI computing environments, efficient power distribution becomes increasingly important.
PDUs help organizations:
- Deliver stable power to servers
- Monitor energy consumption
- Improve operational visibility
- Optimize infrastructure management
