Three-phase PDUs — the power density a modern high-draw rack of servers, storage and switching needs.
As rack density climbs, single-phase power runs out of headroom — a full rack of modern servers, storage and top-of-rack switching can draw more than a single-phase feed comfortably delivers. Three-phase PDUs balance that load across phases and deliver the capacity a high-density rack needs.
This slice locks the catalog to three-phase PDUs. Confirm the feed, voltage and receptacle mix, then send the shortlist as a quote to verify stock and country of origin.

Buyer's checklist
Choosing a three-phase PDU
Confirm the rack is genuinely fed three-phase and the whip/plug type matches — three-phase PDUs require a three-phase supply.
Match input voltage (commonly 208 V) and the plug configuration to the facility feed.
Balance the expected load across phases when planning outlet assignments.
Count receptacles by type (C13/C19) against the equipment, with spares.
Choose metered or switched intelligence for capacity planning and remote control at density.
Every line is screened for TAA country of origin and NDAA §889 status before it ships on a federal order.
FAQ
Common questions
Do I need a three-phase PDU?
You need one when the rack's total draw exceeds what a single-phase feed delivers comfortably — typical of a full rack of modern servers, storage and switching — and the facility provides a three-phase supply. For lighter racks, single-phase is simpler and sufficient.
What voltage and plug do three-phase PDUs use?
Commonly 208 V with a facility-specific three-phase plug, but it varies by deployment and region. Match the PDU's input to your feed exactly. Send a quote with your feed details and we'll confirm the input configuration.
