A PDU distributes electrical power to multiple devices within a server rack. It centralizes power delivery, reducing cable clutter and ensuring each piece of equipment receives necessary power. PDUs are essential for organized and reliable power management in IT environments.

Why is a PDU important for my server rack?

A PDU prevents common power problems like overloads and surges. It ensures consistent power delivery, protects valuable equipment from damage, and minimizes costly downtime. PDUs also enhance organization and improve airflow within the rack, leading to greater efficiency.

What are the main types of PDUs?

PDUs range from basic units that only distribute power to advanced intelligent PDUs. Types include Basic, Metered (for local monitoring), Monitored (for remote monitoring), and Switched (for remote outlet control). Intelligent PDUs combine monitoring and control features.

How do I choose the correct PDU for my needs?

Assess your total amperage and voltage requirements. Count the number of outlets needed for current and future devices. Match the PDU’s NEMA plug and outlet types to your power source and equipment. Consider advanced features like surge protection and remote management.

Do PDUs protect my equipment from power surges?
