APC by Schneider Electric APDU11454SM Netshelter Advanced Switched Metered-by-Outlet Rack PDU
Overview
The APDU11454SM is a 2U horizontal rack PDU from APC's Netshelter Advanced 11K series, purpose-built for high-density three-phase data center and server room deployments where per-outlet control and granular power metering are non-negotiable. Running at a nominal 415 V three-phase input with a 60 A maximum current draw and a 41,400 VA load capacity, this unit is sized for dense compute rows, AI inference clusters, and enterprise network equipment racks where aggregate power demands routinely push into the tens of kilowatts. If you're managing power across a multi-rack data hall and need remote outlet-level switching without dedicated PDU controllers, this is the tier of product to evaluate.
The unit ships in a black horizontal form factor designed to occupy 2U of standard rack space, keeping vertical real estate available for the high-density compute or networking gear it's powering. Managed via APC's NMC3 platform, the APDU11454SM integrates into existing data center infrastructure management (DCIM) environments with a well-supported management card ecosystem.
Key Features
- 41.4 kVA Three-Phase Load Capacity: At 415 V / 60 A three-phase input, this PDU handles up to 41,400 VA — enough headroom for a full rack of high-draw blade servers, GPU compute nodes, or dense network switches running near peak. Size your PDU above 80% of peak load; at 41.4 kVA ceiling, you have real buffer for surge and growth.
- Switched Metered-by-Outlet Control: Each outlet can be switched on/off individually and metered independently — which matters when you need to remotely power-cycle a hung server without touching the rack, or when you need per-device power accountability for chargeback or capacity planning. This is the key differentiator over a basic metered PDU that shows you aggregate draw only.
- 18 AC Outlets (Mixed C13/C15/C19/C21): The outlet mix accommodates standard 1U servers (C13/C14 cords), higher-draw 2U/4U compute (C19/C20 cords), and devices requiring C15 or C21 connectors for elevated-temperature environments. Check your specific outlet count per type in the product documentation — 18 total across all four connector types gives planning flexibility across a heterogeneous rack.
- IEC309 Power Plug Input: The IEC 309 input connector is the industrial-grade standard for three-phase power in data centers — expect a clean, locking connection to your PDU breaker or UPS bypass panel. This is not a standard NEMA plug; ensure your raised-floor power infrastructure is provisioned for IEC 309 before ordering.
- NMC3 Management Platform: APC's third-generation network management card provides the remote monitoring, alerting, and switching interface. NMC3 supports modern security protocols, integrates with SNMP-based monitoring platforms and EcoStruxure IT, and enables scheduled outlet switching — useful for automated load-shedding scripts or maintenance windows.
- IP44 Environmental Rating: IP44 means the PDU is protected against solid objects greater than 1mm and against water splashing from any direction — appropriate for most data center raised-floor and open-frame rack environments. Not rated for washdown or high-humidity plant environments; for those, consult APC's industrial PDU line.
- Wide Operating Temperature Range (-5°C to 60°C): Operational from near-freezing to 60°C ambient means this PDU won't be the limiting factor in a hot-aisle containment environment where rack exit temperatures can spike during cooling failures. The storage range extends to -20°C, so cold-warehouse staging and shipping aren't a concern.
- 50/60 Hz Input Frequency Support: Dual-frequency compatibility makes this unit deployable across North American and European power infrastructure without hardware changes — relevant for multinational data center operators standardizing on a single PDU SKU across regions.
Integration & Compatibility
The APDU11454SM connects to APC's NMC3 management ecosystem, which supports integration with EcoStruxure IT Gateway, SNMP v1/v2c/v3 monitoring, and third-party DCIM platforms. The mixed outlet array (C13, C15, C19, C21) accommodates virtually all enterprise server and networking equipment cord standards. Three-phase deployment requires a matching three-phase UPS or three-phase power distribution infrastructure — verify your upstream UPS output receptacle matches the IEC 309 input specification before commissioning. For large deployments, APC's EcoStruxure IT can aggregate telemetry from multiple APDU11454SM units into a unified power dashboard across the data hall. Pair this PDU with compatible APC UPS systems for a fully integrated power protection and management chain.
Frequently Asked Questions
Q: What is the maximum load capacity of the APDU11454SM?
A: The APDU11454SM supports up to 41,400 VA (41.4 kVA) at 415 V three-phase input with a 60 A maximum current draw. Plan your load at no more than 80% of this ceiling for stable continuous operation.
Q: What outlet types does the APDU11454SM provide?
A: The unit provides 18 AC outlets across four IEC connector types: C13, C15, C19, and C21. This mix accommodates standard 1U servers, higher-draw compute, and elevated-temperature-rated equipment. Verify the per-type outlet count in the product documentation before designing your cable plan.
Q: Can I remotely power-cycle individual outlets on the APDU11454SM?
A: Yes. As a switched metered-by-outlet PDU, the APDU11454SM allows remote on/off control of individual outlets via the NMC3 management card — enabling remote server power cycles, scheduled shutdowns, and outlet-level load management without physical access to the rack.
Q: What management platform does the APDU11454SM use?
A: It uses APC's NMC3 (Network Management Card 3) platform, which supports SNMP monitoring, EcoStruxure IT integration, and standard data center management protocols for remote monitoring, alerting, and control.
Q: Is the APDU11454SM suitable for outdoor or high-humidity environments?
A: The APDU11454SM carries an IP44 rating, providing protection against solid objects over 1mm and water splash from any direction. It is not rated for washdown, submersion, or high-humidity industrial environments. Operating relative humidity range is 5–90% non-condensing.
Q: What input connector does the APDU11454SM require?
A: The unit uses an IEC 309 three-phase input connector — the industrial-standard locking connector for three-phase data center power. This is not a standard NEMA plug; your power infrastructure must be provisioned for IEC 309 before installation.
The APDU11454SM sits at the serious end of the three-phase PDU market — its 41,400 VA load capacity at 415 V three-phase and NMC3-managed per-outlet switching put it squarely in enterprise data center territory, not in a small-room UPS closet. When I spec this unit, the conversation starts with the 60 A maximum current and works backward to the rack design; if your upstream three-phase circuit isn't provisioned for IEC 309 at that amperage, the rest of the PDU's capabilities don't matter.
Technical Highlights:
- 41.4 kVA Three-Phase Capacity: At 415 V / 60 A, this PDU delivers enough headroom for a fully loaded high-density compute rack — GPU nodes, blade chassis, or dense top-of-rack switching — with buffer to absorb inrush without tripping breakers.
- Per-Outlet Switching via NMC3: Remote outlet-level on/off control through the NMC3 card means your NOC can power-cycle a hung device without dispatching a hands-and-eyes tech. In a co-lo or lights-out facility, that's a direct reduction in MTTR for hung hardware.
- Mixed C13/C15/C19/C21 Outlet Array: The four outlet types across 18 total positions accommodate elevated-temperature C15/C21 requirements (common in high-density switching and some server PSU configurations) alongside standard C13/C19 server cord sets — no adapters needed for most enterprise hardware mixes.
Deployment Considerations:
- Verify the IEC 309 three-phase input receptacle is provisioned on your power distribution busway or UPS output before the unit arrives on site — this is a field-fit item, not something you retrofit easily in a hot data hall during a maintenance window.
- The 5–90% operating humidity range and -5°C to 60°C operating temperature cover standard data center envelopes, but the IP44 rating means this is not appropriate for industrial or outdoor enclosures with direct water exposure — select APC's industrial-rated PDU line for those environments.
The APDU11454SM is a strong fit for enterprise colocation deployments, AI compute clusters, and high-density network equipment rows where per-outlet accountability and remote power management are architectural requirements, not optional add-ons.
