Most PDUs do not include built-in surge protection. They focus on overload and circuit protection. For environments with frequent surges, users should pair PDUs with dedicated surge protection devices for complete safety.

How do I choose the right PDU for my equipment?

Users should assess total power needs, outlet types, and future expansion plans. They must ensure compatibility with equipment voltage and connector types. Advanced features like remote monitoring or redundancy may benefit critical environments.

Are smart power strips a good alternative to PDUs?

Smart power strips offer remote control and energy-saving features for home or office use. They do not match the capacity, durability, or advanced management features of PDUs. For critical or high-density setups, PDUs remain the preferred choice.

What safety certifications should I look for?

Look for certifications such as UL, IEC, CE, or CSA. These marks indicate compliance with strict safety and performance standards. Certified devices reduce risks and ensure reliable operation in demanding environments.

Can I daisy-chain power strips or PDUs?

Daisy-chaining power strips or PDUs creates serious fire and overload hazards. Manufacturers strongly advise against this practice. Always connect devices directly to a properly rated outlet or circuit.

When should I upgrade from a power strip to a PDU?

Upgrade to a PDU when equipment count, power demand, or reliability needs exceed what a power strip can handle. Signs include frequent tripping, lack of monitoring, or the need for remote management and scalability.
