Rack PDU Product Lines

Four grades on one hardware platform — metered, switched, outlet-metered and AI rack power. Filter the range by feed, phase, outlet mix and control grade below, or send the load list and an engineer will match the build.

Four filters. One SKU family.

Pick your feed (phase and input current), your outlet plan and the control grade — the table narrows as you go. Every row is a standard build we keep on the line; combinations that come back empty are usually a 14-30 day custom job, not a refusal.

No SKU matches that combination yet — this table lists platform stock builds. Every combination is still manufacturable as a configured order: or ask for a custom build.

NEMA builds (L5-30P, L6-30P, L21-30P) mirror every row above. The AI Rack Power X-Series starts from the O- and S-Series platforms with the full sensor and analytics stack — see AI Rack Power, or the plug-by-plug charts in Selection Guides.

One platform, four grades

All four lines share one firmware image, one SNMP MIB and one mounting system, so a metered row and a switched row read identically in your NMS. That is deliberate — mixed-grade racks are the norm in real deployments, not an exception we tolerate.

Grade comparison

Five grades, side by side

Basic units distribute power and nothing else; every step up adds a specific capability you can point to on a datasheet. FOB bands below reflect standard-config builds — OEM customization moves them, not the platform.

Still torn between two grades? The decision tree in Metered vs Switched vs Outlet-Metered settles it in about four minutes.

Send the load list, get the grade

Feed, phase, outlet count and quantity — an engineer answers within 48 hours with a matched series, a datasheet and FOB pricing. Standard-config samples ship in 3-7 days.
