APC by Schneider Electric Rack PDU 2G Metered-by-outlet Zerou 1 - AP8459WW

APC by Schneider Electric AP8459WW Rack PDU 2G Metered-by-Outlet 0U Vertical

Overview

The AP8459WW is a rack power distribution unit from APC by Schneider Electric built specifically for high-density, space-constrained deployments where per-outlet power visibility matters. As a 0U (zero-rack-unit) vertical design, it mounts in the side channel of a standard rack cabinet, consuming none of your precious rack space while delivering 24 individually monitored AC outlets — a configuration that gives data center managers and IT architects real accountability over every device on the circuit. Whether you're managing a network closet packed with PoE switches, a surveillance NVR stack, or a mixed-load server cabinet, the AP8459WW gives you outlet-level current data without requiring a separate metering device.

Key Features

• 24 AC Outlets (C13 + C19 Mix): The outlet complement covers the widest range of IEC-connected equipment — C13 for standard 1U servers, switches, and NVRs; C19 for higher-draw devices like larger servers or UPS bypass modules. You don't need adapters for mixed-density racks, which reduces cable clutter and failure points.
• Metered-by-Outlet Monitoring: Unlike basic metered PDUs that only show the whole-circuit draw, the AP8459WW reports current, power, and voltage at the individual outlet level. In a 24-outlet rack, that means you can pinpoint which specific device is drawing abnormally — useful both for capacity planning and for post-incident forensics after an unexpected trip.
• 0U Vertical Form Factor: Mounting vertically in the rack's side channel means you retain all 42U (or however many your cabinet provides) for actual equipment. For fully loaded racks, this is not optional — it's the only rational PDU form factor. The AP8459WW is built around this constraint by design.
• 200–230V Input at Up to 16A: Operating on 200–230V input means this PDU is sized for international and high-density domestic deployments where single-phase 230V circuits are standard. The 16A maximum input current per phase and 3,680 VA load capacity gives a fully loaded 24-outlet rack a realistic budget to work within — roughly 153 VA available per outlet at full draw, which aligns with most 1U compute and networking gear.
• LED Indicators for Local Status: On-unit LED indicators provide at-a-glance operational status without needing to navigate a remote interface — useful during physical rack work or emergency triage when you need immediate confirmation that a circuit is live and within parameters.
• Current, Power, and Voltage Monitoring: All three electrical parameters are tracked, not just current. Voltage sag is a common early indicator of circuit overload or upstream power quality issues; having voltage monitoring at the PDU level means you can catch brownout conditions before they affect sensitive equipment.
• RoHS Compliant: The AP8459WW meets RoHS requirements, relevant for deployments subject to EU environmental compliance requirements or enterprise procurement policies that mandate hazardous-substance restrictions.
• Wide Operating Temperature Range (-5°C to 45°C): The -5 to 45°C operating range covers both cold-aisle data center environments running aggressive cooling and warmer edge deployments like telecom closets or industrial IT racks where ambient conditions are less controlled.

Integration and Compatibility

The AP8459WW is designed to fit APC-compatible rack enclosures with vertical PDU mounting channels — verify your cabinet has a vertical rail slot or zero-U bracket before ordering. The 200–230V input voltage range makes it suitable for single-phase international power environments; confirm your local circuit provides a dedicated 20A circuit breaker to support the PDU's 16A maximum draw with appropriate headroom. The C13/C19 outlet combination is broadly compatible with IEC-standard equipment from virtually all enterprise vendors. For deployments where remote outlet switching or outlet-level reboot capability is needed, evaluate the APC Switched Rack PDU family — the AP8459WW provides monitoring but not remote outlet control. If you need PoE switch power distribution at the rack level, pairing this PDU with a PoE planning strategy ensures your switch's power budget aligns with your outlet load expectations.

Frequently Asked Questions

Q: What is the difference between a metered PDU and a metered-by-outlet PDU?

A: A standard metered PDU measures total current draw at the inlet — you see one number for the whole unit. A metered-by-outlet PDU like the AP8459WW measures current, power, and voltage at each individual outlet, giving you device-level visibility across all 24 positions. This matters for capacity planning, troubleshooting, and billing in colocation environments.

Q: Does the AP8459WW support remote outlet switching or outlet-level reboot?

A: No. The AP8459WW is a metered-by-outlet PDU — it provides monitoring but does not include remote outlet switching or reboot capability. For remote outlet control, APC's Switched Rack PDU product line is the appropriate upgrade path.

Q: What input voltage does the AP8459WW require?

A: The AP8459WW is rated for 200–230V AC input at 50–60 Hz, with a maximum input current of 16A per phase. It is not designed for North American 120V circuits. Verify that your installation site has an appropriate 200–230V single-phase circuit with a dedicated 20A breaker before installation.

Q: How much rack space does the AP8459WW consume?

A: The AP8459WW is a 0U (zero rack unit) vertical PDU, meaning it mounts in the side channel or vertical rails of a compatible rack cabinet and consumes no horizontal rack unit space. All 42U (or the full height of your cabinet) remains available for servers, switches, and other equipment.

Q: What outlet types are included on the AP8459WW?

A: The AP8459WW provides a combination of IEC C13 and IEC C19 outlets across its 24 positions. C13 is the standard IEC connector used by most 1U servers, switches, and storage devices; C19 supports higher-current devices. The mixed outlet configuration accommodates varied equipment without adapters.

Q: What is the maximum load capacity of the AP8459WW?

A: The AP8459WW supports a maximum load of 3,680 VA / 3,680W at 200–230V with a maximum input current of 16A per phase. For safe operation, APC and industry best practices recommend loading circuits to no more than 80% of rated capacity, giving a practical operating ceiling of approximately 2,944 VA.

Karl Wilson

The AP8459WW stands out in high-density rack deployments specifically because of its per-outlet current and power metering — not just inlet-level monitoring. In a 24-outlet rack where you're running NVRs, PoE switches, and compute side by side, that granularity is what lets you identify which device is creeping toward its draw limit before it trips the breaker at 2 AM.

Technical Highlights:

• Per-Outlet Metering (Current, Power, Voltage): Three parameters tracked at every outlet — not just amps, but watts and volts. Voltage sag on an individual outlet in a loaded rack is a meaningful early warning signal; most PDUs don't surface this at outlet resolution.
• 3,680 VA / 16A Maximum: On a 200–230V circuit, 16A gives you real headroom for a fully loaded 24-outlet configuration. At 80% utilization (the industry-standard safe ceiling), that's roughly 2,944 VA usable — enough for a dense NVR + switching + compute stack without throttling.
• 0U Vertical Mounting: Vertical installation in the side channel means every U stays available for equipment. On a 42U cabinet running near capacity, this is the only PDU form factor that doesn't force a trade-off between power distribution and usable rack height.

Deployment Considerations:

• Verify your rack cabinet has a vertical PDU mounting channel or zero-U bracket rail before specifying the AP8459WW — not all third-party cabinets include this, and retrofit brackets add cost and complexity.
• This unit is rated for 200–230V only. It will not operate on North American 120V circuits — a common misspecification when procurement teams order internationally sourced PDUs for US data closets without confirming input voltage requirements.

The AP8459WW is the right call for international or 230V-standard deployments — European data centers, Middle East surveillance infrastructure, or enterprise global sites — where a dense rack of NVRs, network gear, and edge compute demands outlet-level power accountability without sacrificing a single U of rack height.
