APC Netshelter Rack PDU Advanced Switched Metered Outlet 11.5KW 3PH 415V 20 - APDU11250SM

APC by Schneider Electric APDU11250SM Advanced Switched Metered Outlet Rack PDU

Overview

The APDU11250SM is a 0U three-phase rack PDU engineered for high-density data center and network equipment rooms where per-outlet switching, outlet-level metering, and remote management are non-negotiable. Rated at 11.5 kW across a 415V, three-phase input, it handles serious power loads — the kind you encounter in fully loaded rack PDU deployments running blade servers, storage arrays, or dense networking infrastructure. With 42 outlets spanning four outlet types and five Ethernet management ports, this unit is built for environments where power visibility and remote control matter as much as raw capacity.

The NMC3 management platform sets the APDU11250SM apart from basic metered PDUs: you get per-outlet switching, real-time outlet-level metering, and remote management through a dedicated out-of-band network interface — so a misbehaving server can be power-cycled without touching the rack or dispatching a technician. That capability translates directly to reduced mean-time-to-recovery in co-location environments and remote edge deployments where hands-on access is expensive or impossible.

Key Features

• 42 Switched and Metered Outlets: Four outlet types (C13, C15, C19, C21) cover virtually every server, storage, and networking power connector in the modern data center. Mixing outlet form factors on a single PDU eliminates the need for adapter cables and reduces the risk of accidental disconnection — important in a dense 42-outlet layout where cables are crowded.
• 11.5 kW / 34,600 VA Load Capacity at 415V Three-Phase: With a 60A maximum input current and three-phase distribution, this PDU can handle the full power budget of a high-density rack. Three-phase input also means balanced loading across phases, which reduces neutral conductor stress and simplifies power infrastructure planning in large data halls.
• NMC3 Management Platform with 5 Ethernet Ports: Five RJ-45 Ethernet ports support network management card connectivity for redundant management paths or daisy-chain configurations. NMC3 delivers HTTPS, SNMPv3, and modern authentication — meeting contemporary security baselines for managed infrastructure.
• 0U Vertical Form Factor: Zero rack unit footprint means the PDU mounts vertically inside the rack without consuming precious 1U or 2U equipment slots. In a fully loaded 42U rack, that distinction directly affects how many revenue-generating compute nodes fit in the cabinet.
• Per-Outlet Switching: Remote outlet switching lets you restart individual loads without cycling the entire PDU or dispatching staff. In co-location and remote-site scenarios, this capability can eliminate a truck roll for a frozen server — a real operational cost reduction at scale.
• 400V Nominal Input / 50-60 Hz: Designed for international three-phase infrastructure at 400–415V, making it compatible with European and international data center power standards. The 50/60 Hz acceptance covers both regional grid frequencies without hardware modification.
• USB Port for Local Management: The single USB port supports local firmware updates and configuration without requiring network access — useful during initial commissioning or when network connectivity to the management interface is unavailable.
• RoHS Compliance: RoHS certification confirms compliance with European hazardous-substance restrictions — relevant for EU deployments and for organizations with environmental procurement requirements.

Integration and Compatibility

The APDU11250SM integrates with APC by Schneider Electric's EcoStruxure IT infrastructure management ecosystem via the NMC3 platform, enabling centralized monitoring, alerting, and automated load management across multiple PDUs. The five Ethernet ports support integration into existing SNMP-based data center infrastructure management (DCIM) platforms. The C13, C15, C19, and C21 outlet mix accommodates standard IEC power cords used across server, storage, and network switch hardware from virtually all major vendors. At 400V three-phase input, the unit requires appropriate three-phase power infrastructure — verify your rack's power feed matches before specifying this model in single-phase environments.

Frequently Asked Questions

Q: What outlet types does the APDU11250SM provide?

A: The APDU11250SM provides 42 total outlets across four IEC connector types: C13, C15, C19, and C21. This mix covers standard servers and switches (C13/C19) as well as higher-temperature-rated applications (C15/C21), allowing a single PDU to serve a mixed-equipment rack without adapter cables.

Q: What is the input voltage and phase requirement for the APDU11250SM?

A: The APDU11250SM requires a three-phase input at 400V nominal (415V rated) with a maximum current of 60A. It accepts both 50 Hz and 60 Hz input frequencies. This unit is not compatible with single-phase power feeds — confirm your rack's power infrastructure before ordering.

Q: How does the NMC3 management platform differ from basic PDU management?

A: NMC3 provides per-outlet switching and metering over a dedicated out-of-band network interface with support for SNMPv3, HTTPS, and modern authentication protocols. Unlike basic metered PDUs that only report aggregate load, NMC3 enables remote power cycling of individual outlets, real-time per-outlet current monitoring, and integration with DCIM platforms — without requiring physical access to the rack.

Q: Does the APDU11250SM occupy rack units (U) inside the cabinet?

A: No. The APDU11250SM is a 0U (zero rack unit) PDU, meaning it mounts vertically along the side or rear of the rack and does not consume any horizontal rack unit slots. All 42U of equipment space in the cabinet remains available for compute or network hardware.

Q: Is the APDU11250SM RoHS compliant?

A: Yes. The APDU11250SM carries RoHS certification, confirming it meets EU restrictions on hazardous substances. This is relevant for EU deployments and for organizations with environmental or sustainability-based procurement policies.

Q: Can the APDU11250SM be used with single-phase power distribution?

A: No. This PDU is designed exclusively for three-phase power infrastructure at 400–415V. If your facility uses single-phase distribution or North American 208V three-phase, a different PDU model in the APC Netshelter family would be required.

When I look at the APDU11250SM, the spec that immediately stands out is the 34,600 VA load capacity at 60A across a 415V three-phase input. That's not a PDU you spec for a light-duty equipment closet — that's a unit for high-density compute racks where every outlet is loaded and every watt is accounted for. The combination of 42 switched metered outlets and NMC3 makes this a serious infrastructure management tool, not just a power strip.

Technical Highlights:

• 42-Outlet Mixed Connector Layout (C13/C15/C19/C21): Having all four IEC outlet types on a single unit eliminates the adapter-cable clutter that accumulates in dense racks over time and reduces the risk of accidental disconnection during cable management.
• NMC3 with 5 RJ-45 Ethernet Ports: Five Ethernet management ports support redundant management paths or daisy-chain PDU topologies — particularly useful in large deployments where you need consolidated SNMP polling without adding per-PDU network drops.
• 0U Vertical Mounting: Zero rack unit consumption is non-trivial at current compute-to-rack ratios. Preserving all 42U for revenue-generating hardware is a real factor in co-location billing environments where rack space is charged by the U.

Deployment Considerations:

• Verify your raised-floor or overhead power feed delivers 400–415V three-phase at 60A before specifying this model. The APDU11250SM is built specifically for international three-phase infrastructure — mismatching the input voltage is a commissioning failure, not a field-adjustable setting.
• The 56mm width and 75mm depth are the PDU body dimensions; confirm your chosen rack's vertical PDU channel accommodates this profile, particularly in non-APC cabinets where the mounting rail geometry may differ.

The APDU11250SM is the right call for international co-location facilities, enterprise data centers running European power infrastructure, or any high-density rack environment where remote outlet-level control and per-outlet metering need to coexist in a zero-U footprint.
