What is a basic PDU?

A basic PDU is a power distribution unit that does one job: it takes power from a single input and spreads it across several outlets. It has no network connection, no remote control and usually no display. It is the simplest type of rack PDU and is often called an unmanaged PDU.

What it looks like

Most basic PDUs are strip-shaped, with a row of outlets. They mount vertically (0U) on the side of the rack or horizontally (1U or 2U) in the rack space. A power cord connects to a wall outlet or power feed.

Key specifications

• Input voltage: 120 V, 208 V or 230 V.
• Current rating: for example 15 A, 20 A or 30 A.
• Outlet types: C13 for most servers and C19 for larger equipment, or standard wall-style outlets.
• Outlet count: 6 to 42 outlets.
• Circuit breaker: protects against overload on many models.

Basic PDU vs other PDUs

• Basic: power distribution only.
• Metered: shows load on a local display.
• Monitored: reports load over the network.
• Switched: adds remote outlet control.

When a basic PDU is enough

• Small racks or network closets.
• Budget setups.
• Racks where you do not need remote monitoring.
• Lab and test equipment.

Safety tips

Do not exceed 80 percent of the PDU's rated current for continuous loads. Do not plug one PDU into another. Match the PDU's input plug to your power circuit.

If you need to see power use or reboot devices remotely, choose a metered or managed PDU.
