Server Technology SEV-6542M 8.6kW Switched 0U Rack PDU

Overview

The Server Technology SEV-6542M is a 3-phase, 0U rack-mount power distribution unit built for data center racks where per-outlet control and monitoring matter more than floor space. Rated at 8.6kW total capacity on a 30A/208V input, this PRO2 Switched POPS unit gives you 24 total outlets — 18x C13 and 6x C19 — with per-input and per-outlet power sensing on every receptacle. If you're specifying PDUs for a rack full of mixed-load servers, switches, and storage arrays and you need to know exactly what each device is drawing without walking the row, the SEV-6542M is built for that job specifically.

Key Features

• Per-Outlet Power Sensing: Every one of the 24 outlets reports its own current draw independently, so you can identify a runaway server or a failing PSU from the management interface instead of physically tracing cables in a live rack.
• Switched Outlets: Each outlet can be individually powered on or off remotely — useful for sequenced boot-up after a UPS event, or for hard-power-cycling a hung server without a truck roll to the data center floor.
• 8.6kW Total Power Capacity: On a 30A/208V 3-phase input, 8.6kW gives you headroom for a densely populated rack of 1U/2U servers without tripping the branch circuit — size your rack load against this ceiling before you commit outlets.
• 18x C13 + 6x C19 Receptacle Mix: The C13/C19 split matches typical rack gear directly — C13 for standard servers, switches, and low-draw devices; C19 for higher-current equipment like blade enclosures or dense storage arrays — without needing adapter cables that add failure points.
• NEMA L21-30P Input: A locking twist-lock plug rated for the full 30A input current, so the PDU won't work itself loose under cable weight and vibration in a populated cabinet — check that your PDU whip or receptacle matches this connector before ordering.
• 0U Rackmount Form Factor: At 69 inches tall by 2.2 inches wide by 2.25 inches deep, this vertical zero-U unit mounts in the rear rack channel and consumes none of your usable 1U/2U rack space — every slot stays available for compute and storage.
• 24 Total Outlets: A high outlet count on a single 0U strip means fewer PDUs per rack and fewer power whips to route and label, simplifying both the initial install and future moves/adds/changes.
• 10ft Cord Length: Reaches from a top-of-rack or bottom-of-rack PDU mounting position to a standard overhead or underfloor PDU receptacle without requiring an extension whip.
• 50/60 Hz Frequency Support: Runs on both 50Hz and 60Hz utility power, so the same SKU deploys in North American 60Hz facilities or 50Hz regions without a model change.

Integration & Compatibility

As a member of the Server Technology PRO2 Switched POPS family within the broader Server Technology catalog, the SEV-6542M fits standard 3-phase 208V data center power infrastructure. It's built for racks already standardized on power distribution units with remote outlet control and branch-circuit monitoring — pair it with your existing rack PDU management platform where per-outlet telemetry is already part of your monitoring stack. For teams still working out rack power budgets before ordering, a PDU sizing and power planning guide is worth reviewing before you commit to outlet count and phase configuration. If this rack also carries edge compute or storage that needs UPS backup, plan the upstream UPS systems capacity against this PDU's 8.6kW draw, not just the PDU in isolation.

Frequently Asked Questions

Q: How many outlets does the SEV-6542M have?

A: 24 total outlets — 18x C13 and 6x C19 — each with independent power sensing.

Q: What input connector does the SEV-6542M use?

A: A NEMA L21-30P locking twist-lock plug rated for the unit's 30A input current.

Q: Can outlets on the SEV-6542M be switched individually?

A: Yes, this is a Switched POPS model — each outlet can be powered on or off independently, and each reports its own power draw.

Q: Does the SEV-6542M take up rack unit space?

A: No. It's a 0U vertical form factor, 69 inches tall, that mounts in the rear rack channel without consuming 1U/2U slots.

Q: What's the total power capacity of the SEV-6542M?

A: 8.6kW on a 30A, 208V, 3-phase input at 50/60 Hz.

Q: How long is the input power cord on the SEV-6542M?

A: 10 feet.

The SEV-6542M is a PDU I'd spec for a rack where you actually need to know per-outlet draw, not just total branch amperage. With 24 outlets each reporting independently, this isn't a dumb power strip with a fancy name — it's a monitoring point for every device in that cabinet.

Technical Highlights:

• Per-Input and Per-Outlet Power Sensing: Granular current data on all 24 outlets means you can spot a drifting PSU or an overloaded circuit before it trips the 30A input feed.
• 8.6kW at 30A/208V 3-Phase: That capacity on a single L21-30P feed is enough for a dense 42U rack of 1U servers — run your load math against 8.6kW before you populate every outlet.
• 18x C13 + 6x C19 Mix: Six C19 outlets give you headroom for higher-draw gear like blade chassis or storage shelves without daisy-chaining adapters onto C13 receptacles.

Deployment Considerations:

• The 0U form factor at 69" tall mounts vertically in the rack's rear channel — confirm your cabinet has rear mounting rails clear of cable management arms before ordering.
• The NEMA L21-30P input is a locking twist-lock connector — make sure your upstream PDU receptacle or facility whip matches this plug type; it won't mate with a standard L6-30 without an adapter.

This is the right call for a colocation or enterprise data center cage standardizing on remote-switched, per-outlet-metered PDUs across multiple racks — not for a small server closet where a fixed unmetered strip would do the job for less.
