APC Netshelter Rack PDU Advanced Switched Metered Outlet 8.6KW 3PH 208V 30A - APDU11351SM

APC by Schneider Electric APDU11351SM Advanced Switched Metered Outlet Rack PDU

Overview

The APC by Schneider Electric APDU11351SM is a 3-phase, 208V, 30A rack-mounted power distribution unit built for dense data center and network closet environments where per-outlet power visibility and remote switching are non-negotiable. At 8,600 VA of load capacity with 24 output connections spanning C13, C15, C19, and C21 receptacle types, this unit handles mixed server, storage, and high-draw appliance loads from a single PDU — reducing the number of discrete power runs and simplifying cabinet power architecture. If you're managing rack power in a surveillance control room, a network operations center, or a compute-dense server bay, the APDU11351SM delivers the granular load data and remote outlet control that separates proactive power management from reactive firefighting.

This unit is part of the APC by Schneider Electric Netshelter lineup and belongs to the rack PDU category covering advanced metered and switched configurations. For PoE infrastructure supplying IP cameras or access control readers, pair this with a review of your PoE switch power budget — the APDU11351SM governs the upstream AC side feeding those switches.

Key Features

• Per-Outlet Switching at 8,600 VA: Each outlet can be individually switched on, off, or power-cycled remotely — critical for rebooting a locked-up NVR, a hung access controller, or a misbehaving PoE injector without dispatching a tech to the rack. At 8.6kW total capacity on a 30A, 3-phase 208V feed (NEMA L21-30P input), this PDU supports fully loaded cabinets without derating concerns on typical data center branch circuits.
• 1% Metering Accuracy Across All 24 Outlets: Most basic metered PDUs tell you total load. The APDU11351SM tells you exactly what each outlet is drawing, accurate to ±1%. That precision matters when you're trying to identify which device is overconsumming, validating nameplate vs. actual draw for a UPS sizing exercise, or proving SLA compliance to a colocation provider. Guessing at load distribution is a liability — this removes it.
• 24 Mixed-Receptacle Outputs (C13/C15/C19/C21): The combination of C13, C15, C19, and C21 receptacle types means you can connect standard 1U servers (C13), high-temperature-rated devices like some PDUs and UPS units (C15), high-draw appliances up to 20A (C19), and high-current locking loads (C21) — all from one unit. No adapters, no pigtails, no improvised cabling that voids insurance coverage.
• 10/100/1000 Ethernet with 32-Unit Network Port Sharing: A single IP address can manage up to 32 daisy-chained PDUs via the two onboard link ports — a significant operational savings in large deployments. Rather than burning 32 switch ports and 32 management IPs on a full cage of PDUs, you use one switch port, one IP, and manage the entire row from a single pane of glass. The gigabit Ethernet port ensures the management plane doesn't become a bottleneck during bulk polling or firmware updates.
• 10 ft. (3 m) Input Cord: The factory-supplied 10-foot cord gives enough slack to reach a PDU-level breaker or whip panel without forced cable management gymnastics — particularly useful in overhead busway or under-floor power configurations where the panel is not always immediately adjacent to the rack.
• 60°C Maximum Operating Temperature: Rated to operate at up to 60°C (140°F), this PDU won't derate or fault in hot-aisle/cold-aisle containment environments where ambient near the exhaust face of servers can spike well above normal room temperature. That headroom is meaningful in high-density deployments where thermal management is already a design constraint.
• 3-Phase 208V Input Architecture: Drawing from a 3-phase 208V source via NEMA L21-30P distributes load across all three phases, reducing imbalance on the building's electrical infrastructure compared to single-phase alternatives. For facilities with 3-phase distribution panels already in place, this is the correct topology — and at 30A input, it fits standard branch circuit protection without special wiring.

Integration and Compatibility

The APDU11351SM integrates into APC's EcoStruxure IT and Data Center Expert platforms for centralized monitoring, alerting, and remote control. Network port sharing with up to 32 units over a single IP simplifies integration into network management frameworks and DCIM tools. The unit's standard receptacle mix (C13 through C21) is compatible with virtually all rack-mounted IT equipment from major compute, storage, and networking vendors. For physical infrastructure planning, consult a rack power planning guide to match PDU capacity against your actual connected load and UPS runtime calculations before deploying at scale.

Frequently Asked Questions

Q: What input plug type does the APDU11351SM use, and what does that mean for installation?

A: The APDU11351SM uses a NEMA L21-30P input plug — a 3-phase, 30A, 208V locking connector. Your facility must have a compatible 3-phase 208V branch circuit with an L21-30 receptacle or panel termination. This is standard in data center and colocation environments but requires confirmation before ordering if you're retrofitting an existing cabinet.

Q: How accurate is the per-outlet metering on the APDU11351SM?

A: Per-outlet metering accuracy is ±1%. This is sufficient for load balancing, capacity planning, and UPS sizing validation. It is not a revenue-grade power meter, but it is accurate enough for all typical IT infrastructure management use cases.

Q: Can multiple APDU11351SM units share a single network connection?

A: Yes. The APDU11351SM supports network port sharing with up to 32 units linked via its two onboard link ports. All 32 units are managed under a single IP address, which conserves switch ports and simplifies DCIM integration in large deployments.

Q: What outlet types are available on the APDU11351SM?

A: The PDU provides 24 output connections using a mix of C13, C15, C19, and C21 IEC receptacle types, accommodating standard servers, high-temperature-rated devices, and higher-current appliances without adapters.

Q: What is the maximum operating temperature for the APDU11351SM?

A: The APDU11351SM is rated to operate at up to 60°C (140°F), making it suitable for hot-aisle containment and high-density rack environments where exhaust-side ambient temperatures regularly exceed normal room temperature.

Q: What is the total power capacity of the APDU11351SM?

A: The APDU11351SM supports up to 8,600 VA (8.6kW) of connected load on a 30A, 3-phase 208V input circuit — appropriate for fully loaded 42U or 48U cabinets in compute and storage deployments.

The APDU11351SM sits at the intersection of two demands I see constantly in dense security and compute deployments: the need to actually know what each device is drawing (not just the circuit total), and the ability to remotely reboot a specific outlet without touching the cabinet. That 1% per-outlet metering accuracy isn't marketing — it's the difference between a capacity planning spreadsheet built on guesses and one built on real numbers, which matters the moment you're trying to justify adding four more NVRs to an existing UPS.

Technical Highlights:

• 8,600 VA on 3-Phase 208V: Drawing from all three phases via NEMA L21-30P keeps your building electrical balanced and gives you the headroom to fill a 42U cabinet without worrying about branch circuit overload — provided the upstream panel is properly provisioned for 30A 3-phase.
• 32-Unit Network Port Sharing: One switch port, one IP, up to 32 PDUs — this scales to a full row of cabinets without burning your management VLAN or your switch port budget. In a surveillance operations center with 8-10 racks, that's a meaningful operational simplification.
• 60°C Operating Rating: Hot-aisle containment regularly pushes exhaust-side ambient above 45°C in high-density rows. The 60°C ceiling on the APDU11351SM means you're not adding PDU thermal failures to your risk register alongside server thermals.

Deployment Considerations:

• Confirm NEMA L21-30 receptacle availability at the rack position before ordering — retrofitting a 3-phase 208V circuit into an existing cabinet run that was wired for single-phase requires an electrician and potentially a panel change, not just a new PDU.
• Network port sharing requires daisy-chaining via the two link ports in the correct sequence; a broken link in the chain will drop management visibility for all downstream units, so document the chain topology and test it before closing the cabinet.

For a physical security control room running a mixed load of NVRs, access control servers, managed switches, and workstations — where individual outlet reboot capability and precise load data are operationally necessary — the APDU11351SM is the right PDU tier to specify. It is not the answer for a simple single-phase 120V closet; for that, a basic metered unit will do. But wherever 3-phase 208V distribution and per-outlet control intersect, this unit earns its place in the design.
