Three jobs, three types
A rack PDU is a power strip built for a cabinet. The type name describes what it can tell you and what it can do, not the quality of the metal.
| Type | What you get | Choose it when |
|---|---|---|
| Basic | Outlets and a breaker or fuse | The rack only needs power distributed |
| Metered | A load reading at the inlet, and sometimes per outlet | You need to know how full the feed is |
| Switched | Metering plus remote on/off per outlet | Someone must reboot equipment off site |
Decide the power before the features
Write down the input first. Single phase or three phase, the amperage, and how the PDU is fed: an IEC inlet and a cord, a local plug (British, French, German, and others appear on Legrand LCS³ strips), or a terminal block. A PDU with the wrong plug is the wrong PDU even if the outlet count matches.
Then count outlets. IT kit is usually C13 for lighter equipment and C19 for heavier supplies. High-density strips pack more C13 outlets into a vertical (zero-U) body. A 1U horizontal PDU suits a wall cabinet or a rack that cannot take a vertical strip. Local 2P+E sockets show up where the equipment is not IEC.
Leave headroom. A feed that sits near the breaker all day will trip when a second supply fails over or when new kit is added. Metering is how you see that before it happens. If nobody will ever look at the number, a metered PDU does not help, and a basic unit is the honest choice.
Ordering from AmberWork Source
The Legrand reference (for example 646800) is printed on each product page, with the form factor, outlet mix, and cord. AmberWork Source quotes these PDUs from Singapore. Send the rack count, the input, and a photo or list of the outlets you need. If the exact reference is not listed, ask — the team can source against a bill of materials.
Cable tray and pathway for the power and data cords are a separate Legrand Cablofil conversation. The PDU page does not include Cablofil baskets.
