APC Rack PDU 9000 Switched Zerou 16A - APDU9959EU3

APC by Schneider Electric APDU9959EU3 0U Vertical Switched Rack PDU

Overview

The APC by Schneider Electric APDU9959EU3 is a zero-U vertical switched rack PDU designed for data centers and high-density rack deployments where per-outlet power control matters. Mounting vertically inside the rack cabinet, it reclaims every horizontal rack unit for compute, storage, or networking — a meaningful advantage in fully populated racks where space is the constraint. With 24 individually switched outlets across C13 and C19 socket types, this PDU handles everything from 1U servers to high-draw storage arrays and network switches without requiring a separate PDU per device tier.

For integrators building out rack power distribution infrastructure, the APDU9959EU3 sits in APC's Rack PDU 9000 family — a line focused on switched outlet-level control with network management capabilities.

Key Features

• Zero-U Vertical Mounting: Mounts inside the vertical channel of standard rack cabinets, consuming zero horizontal rack units. In a 42U rack fully loaded with 1U servers, that's 42 usable compute slots instead of 40 — and the cabling stays organized along the vertical run rather than draping across equipment.
• 24 Switched AC Outlets (C13 + C19): The mix of C13 and C19 sockets lets you connect standard IEC C14-corded servers alongside high-draw C20-corded devices like large storage arrays or high-density switches — no adapters needed. Switched control means you can remotely reboot a hung server or cut power to a specific device without touching the rack.
• 16A / 230V Input via IEC 60309: The IEC 60309 industrial-grade plug delivers up to 3,680 VA load capacity at 16A. That's enough headroom for a dense rack without hitting thermal cutoffs under normal operating loads. The 50–60 Hz input frequency range also means this PDU moves between European and international deployments without modification.
• LCD Display: The onboard LCD provides local readout of load, voltage, and current without requiring a laptop or network connection. During initial commissioning or a network outage, you get real power data at the rack face — not a guess based on theoretical load calculations.
• Daisy-Chain Support: Connect multiple APDU9959EU3 units together to extend switched outlet coverage across wider rack rows or high-density deployments. A single upstream network connection can manage the daisy-chained group, reducing switch port consumption in the management network.
• 3-Meter Power Cord: The 3m cable gives enough slack to route cleanly from a floor-mounted PDU breaker panel or overhead busway to the vertical PDU position without pulling taut or kinking — relevant in deep cabinets and raised-floor environments where the feed comes from below.
• Single-Phase Architecture: Straightforward single-phase design keeps electrical planning simple for environments that don't require three-phase distribution. If your facility runs standard single-phase 230V circuits to each rack, this PDU fits directly without additional step-down or balancing hardware.
• Black Finish: Matches standard rack cabinet interiors — no mismatched panel colors in customer-facing data center tours or co-location environments where aesthetics matter alongside function.

Integration and Compatibility

The APDU9959EU3 accepts devices with standard IEC C14 and C20 power cords via its C13 and C19 outlets respectively — compatible with virtually all rack-mount servers, switches, and storage units from major vendors. The IEC 60309 input plug is standard in European commercial electrical infrastructure. For environments running managed network switches and high-density compute, the switched outlet control integrates with APC's network management card ecosystem for SNMP and web-based remote power management. Daisy-chaining expands outlet count without multiplying management complexity, making this PDU a practical fit for rack-mount UPS fed rows. For deployments planning full infrastructure rollouts, also consider APC's compatible rack enclosures and environmental monitoring accessories available in the broader APC product line.

Frequently Asked Questions

Q: What input plug type does the APDU9959EU3 use?

A: The APDU9959EU3 uses an IEC 60309 industrial-grade input plug, rated for 16A at 220–240V single-phase.

Q: Can the APDU9959EU3 be mounted horizontally in a rack?

A: No — this is a zero-U vertical PDU designed to mount inside the vertical channel of a rack cabinet. It does not occupy horizontal rack units and is not designed for horizontal installation.

Q: What outlet types are on the APDU9959EU3?

A: The PDU provides 24 AC outlets in a mix of C13 and C19 socket types, accommodating both standard IEC C14 corded devices and higher-current IEC C20 corded equipment.

Q: Does the APDU9959EU3 support daisy-chaining to other PDUs?

A: Yes — the APDU9959EU3 supports daisy-chaining, allowing multiple units to be linked together and managed through a single network connection.

Q: What is the maximum load capacity of the APDU9959EU3?

A: The APDU9959EU3 supports up to 3,680 VA load capacity based on its 16A / 230V single-phase input rating.

Q: Does the APDU9959EU3 have a built-in display?

A: Yes — an LCD display is built in, providing local visibility into load, voltage, and current at the rack face without requiring a network connection.
