The PDU is where a rack's power planning becomes physical. This selection runs from basic rack power strips to metered and switched units that report and control power per outlet, in the horizontal and vertical form factors that match how racks are actually built.
Start from the circuit: the PDU's input plug and amperage must match the receptacle feeding it, and the outlet types and count must match the equipment list - counted with spares, because a full PDU on installation day is a return ticket. Metered units earn their premium the first time a circuit approaches capacity; switched units add remote power-cycling, which pays for itself at any site without hands nearby. Racks with dual-corded equipment need paired PDUs on independent circuits to deliver the redundancy the equipment was bought for. COLAMCO quotes rack power for business, government, and education facilities, and an account manager can check PDU selections against a rack elevation and its circuits.
