APC by Schneider Electric APDU10351SM Advanced Switched Metered Outlet Rack PDU
Overview
The APDU10351SM is APC's advanced switched, metered-outlet rack PDU designed for high-density data center and server room deployments where per-outlet remote switching and granular power measurement matter. Running on 3-phase 208V at up to 30A input, this unit delivers 8.6kW of load capacity across 48 individually switched outlets — enough to feed a fully populated 42U cabinet while retaining the ability to remotely cycle any single device without touching the rack. The 0U vertical form factor keeps it mounted flush in the rear of the rack, preserving every usable rack unit for compute and networking gear. If your team manages distributed racks across multiple floors or remote sites, the per-outlet switching on the APDU10351SM is the operational capability that eliminates truck rolls for a hung server or a device that just needs a hard power cycle.
Key Features
- 8.6kW / 208V Load Capacity: At 8,600 VA on a 30A 3-phase 208V circuit, this PDU can support a fully populated high-density rack without approaching the 80% NEC derate threshold — you get roughly 24A of usable continuous draw before the breaker side gets nervous. That headroom matters in mixed compute environments where bursts are common.
- 48 Switched Outlets Across Four Connector Types: The outlet mix — C13, C15, C19, and C21 couplers — covers virtually every standard IEC load you'll encounter: 1U servers and switches on C13, hot-environment equipment (60°C-rated C15), high-draw blade chassis and UPS feeds on C19, and C21 for the heaviest 20A+ loads. No need for adapter cables or secondary power strips inside the rack.
- Per-Outlet Switching: Remote on/off control per outlet means you can reboot a locked-up device, sequence startup order during recovery, or isolate a failing load — all from your management interface without physical access. In co-location environments or remote facilities, this pays back its cost the first time it prevents an after-hours site visit.
- Outlet-Level Metering: Metered outlet visibility tells you exactly which device is drawing what. This is the spec that catches the server pulling 18A that your asset inventory says should pull 8A — before it trips a breaker at 2am. Capacity planning becomes fact-based rather than estimate-based.
- 0U Vertical Mounting: Zero rack unit consumption means your 42U or 45U cabinet stays fully available for revenue-generating hardware. The vertical PDU mounts in the side channel of standard EIA-310 racks. No compromise on cabinet density.
- LCD Display: The onboard LCD provides local readout of load and status without requiring a laptop or network connection — useful during initial commissioning or when network management is down.
- Daisy-Chain Support: Multiple PDUs in the same rack can be daisy-chained, reducing cable runs and management overhead in high-density deployments where two or three PDUs feed a single cabinet.
- 50–60Hz Input Compatibility: Works on both North American (60Hz) and international (50Hz) power infrastructure — relevant for organizations with mixed global data center footprints or equipment sourced for dual-region deployment.
- Maximum 24A Continuous Draw: The 24A maximum total current draw per phase reflects the 80% derating rule baked into the product spec. You get a PDU that self-limits within safe operating parameters rather than one that lets you run to the edge of the breaker.
Integration and Compatibility
The APDU10351SM is designed for integration into APC's EcoStruxure IT and NetShelter rack ecosystem. The switched outlet architecture supports sequenced power-on scripting, which pairs well with DCIM platforms that require controlled startup sequences after a site power event. The four IEC outlet types accommodate standard server, networking, and storage equipment without adapters, and the daisy-chain capability simplifies cabling in multi-PDU cabinet configurations. For organizations running rack power and UPS infrastructure, the per-outlet metering feeds into broader capacity and power monitoring workflows. Pair with an APC UPS upstream for full runtime and conditioning coverage. Those building out or refreshing network switching infrastructure alongside compute will find the C19/C21 outlet availability directly relevant for higher-draw line cards and chassis switches.
Frequently Asked Questions
Q: What outlet types does the APDU10351SM include?
A: The APDU10351SM includes C13, C15, C19, and C21 IEC coupler outlets across its 48 switched positions, covering standard 1U servers, hot-rated equipment, high-draw chassis, and 20A+ loads without adapters.
Q: What is the maximum load the APDU10351SM can handle?
A: The unit supports up to 8,600 VA (8.6kW) at 208V with a 30A maximum input current per phase. Continuous draw is derated to 24A per phase per standard electrical practice.
Q: Does the APDU10351SM support remote outlet switching?
A: Yes. The APDU10351SM is a switched PDU, meaning each of its 48 outlets can be individually turned on or off remotely — useful for device reboots, controlled startup sequencing, and load isolation without physical rack access.
Q: How is the APDU10351SM mounted in a rack?
A: The APDU10351SM is a 0U vertical PDU that mounts in the side channel of a standard EIA-310 rack, consuming no rack unit space inside the cabinet.
Q: Can multiple APDU10351SM units be daisy-chained?
A: Yes. The APDU10351SM supports daisy-chaining, allowing multiple units to be linked in the same rack to reduce separate cable runs and simplify management in high-density cabinet configurations.
Q: What input voltage and frequency does the APDU10351SM require?
A: The unit requires 208V 3-phase input and accepts both 50Hz and 60Hz supply frequencies, making it compatible with North American and international power infrastructure.
The APDU10351SM hits the spec combination I look for in high-density data center refreshes: 48 individually switched outlets across C13/C15/C19/C21 on a single 0U vertical unit, with 8.6kW capacity and per-outlet metering baked in. The per-outlet switching is the feature that actually changes operational behavior — it's not just a convenience, it's what lets a lean ops team manage remote racks without scheduling site visits every time a device needs a hard reboot.
Technical Highlights:
- 48 Switched Outlets: Individual remote switching on all 48 outlets covers a fully loaded cabinet — servers, switches, storage — with enough granularity to isolate any single load without affecting neighbors.
- 8.6kW / 30A Input: The 30A input with 24A continuous draw rating means you're operating within the NEC 80% rule by design, not by guesswork. For a 208V 3-phase feed, that's legitimate headroom for bursty compute workloads.
- C13/C15/C19/C21 Mix: The four outlet types eliminate the adapter clutter that typically accumulates in mixed-load cabinets. C15 slots handle hot-aisle applications where standard C13 cords are technically out of spec; C21 handles the 20A chassis loads that C19 doesn't cover.
Deployment Considerations:
- Daisy-chain support is valuable in dual-corded cabinet designs — but confirm your management network can handle the additional device count before chaining multiple units per cabinet, as each PDU adds to your SNMP/management polling load.
- The 24A continuous draw ceiling is already derated for you, but verify your upstream breaker and PDU input cable are rated for 30A — the PDU will accept 30A momentarily even if your ops policy limits steady-state to 24A.
The APDU10351SM is well-suited for enterprise co-location deployments and multi-tenant data center environments where remote hands are expensive and per-outlet accountability is a billing or chargeback requirement — particularly where the outlet type mix (C13 through C21) needs to accommodate both standard 1U gear and high-draw blade or storage chassis in the same cabinet.
