Common Questions
What is a rack PDU?
A rack PDU is a power strip designed for 19-inch racks that distributes power from the rack feed to servers, switches and storage, usually through IEC C13 and C19 outlets.
Should I choose a 1U or Zero-U PDU?
1U horizontal PDUs suit small racks with few devices; Zero-U vertical PDUs mount at the back or side of the rack, save rack space and provide more outlets.
