APC by Schneider Electric AP7553 Vertical 0U Basic PDU — 24-Outlet, 32A, 7680 VA
Overview
The APC by Schneider Electric AP7553 is a 0U vertical basic PDU designed to deliver reliable, high-density power distribution inside a standard two-post or four-post rack without consuming any rack unit space. Mounting vertically in the side channel of your rack enclosure, the AP7553 frees every RU for active equipment — a practical consideration in dense compute or surveillance server builds where space is a real constraint. With a 32A IEC 60309 input, 7680 VA load capacity, and 24 IEC 320 outlets split across C13 and C19 form factors, this unit covers the mixed-load profiles common in network closets, security headend rooms, and edge server deployments. It's a straightforward, no-managed-overhead solution: plug in, distribute power, move on.
Key Features
- 24 Outlets for Mixed Equipment Loads: The AP7553 provides (20) IEC 320 C13 outlets for standard 1U/2U servers, switches, and NVRs, plus (4) IEC 320 C19 outlets for higher-draw equipment like UPS bypass modules or high-wattage storage arrays. Having both outlet types on a single PDU eliminates the need for adapter cords on most rack builds.
- 32A IEC 60309 Input — No Derating Surprises: The IEC 309 32A input plug connects directly to a dedicated 32A single-phase circuit. At 7680 VA maximum load capacity, you have the headroom to populate most of the outlets under realistic mixed loads without hitting the 80% continuous-load ceiling prematurely. Size your circuit at 32A and you're covered.
- 7680 VA Load Capacity: At 230V nominal with a 32A maximum input current, this PDU can handle fully populated racks in surveillance-server, NVR-cluster, or edge-compute environments. Eight kilowatts of distribution on a zero-U footprint is a meaningful spec when you're planning a dense headend room.
- 0U Vertical Form Factor — Rack Space Preserved: The vertical mounting profile means the AP7553 lives in the cable management channel alongside your rack rails, not in your equipment bays. In a 42U enclosure, that's 42U of usable rack space preserved for the gear that matters — important when you're adding cameras and NVRs quarter by quarter.
- Single-Phase, 230V Nominal Input/Output: Both input and output are rated at 230V nominal, making the AP7553 a direct fit for European and international single-phase infrastructure as well as 200–208V environments where IEC 309 circuits are provisioned. Confirm your facility's circuit voltage before ordering — this is not a step-down transformer.
- Black Finish for Standard Rack Aesthetics: The black enclosure blends with most commercial rack cabinets. Minor detail, but worth noting in customer-facing server rooms where a coherent equipment appearance matters.
- Basic PDU — No Network Overhead: The AP7553 is classified as a basic (non-metered, non-switched) PDU. There is no network interface, no SNMP agent, and no per-outlet switching. If your deployment requires remote outlet cycling, per-outlet metering, or outlet-level scheduling, you'll need a metered or switched variant from the APC by Schneider Electric PDU line. For straightforward always-on rack power distribution, the basic format keeps cost down and complexity out.
Integration and Compatibility
The AP7553 integrates into any rack power distribution architecture that supports a 32A single-phase IEC 309 source. The outlet complement — 20 C13 plus 4 C19 — matches the power inlet types used on most 1U rack servers, managed switches, network video recorders, and PoE injectors without requiring adapters. Pair this PDU with a compatible UPS unit upstream to add runtime and surge protection; the AP7553 itself provides no surge suppression or battery backup. For rack deployments where per-outlet monitoring is required for uptime reporting or facilities billing, consider a metered PDU variant in the same family that adds current measurement without changing the outlet layout. When planning rack cabling, factor in the 3.05m (approximately 10 feet) of included input cord length — sufficient to reach a floor-mounted PDU tap or a rear-mounted rack power strip panel in most standard enclosures.
Frequently Asked Questions
Q: What input plug does the AP7553 use, and what circuit does it require?
A: The AP7553 uses an IEC 60309 32A input plug. It requires a dedicated single-phase 32A circuit at 230V nominal. Do not attempt to connect it to a standard 16A or 20A outlet — the inlet is physically keyed to 32A IEC 309 connectors only.
Q: How many outlets does the AP7553 have, and what types?
A: The AP7553 provides 24 total AC outlets: 20 IEC 320 C13 outlets (for standard server and networking equipment) and 4 IEC 320 C19 outlets (for higher-draw devices). All outlets are clearly marked on the unit.
Q: Does the AP7553 have remote management or per-outlet switching?
A: No. The AP7553 is a basic PDU — it has no network interface, no SNMP, and no outlet switching capability. Power to all outlets is always-on when the unit is energized. If you need per-outlet control or remote monitoring, you'll need a switched or metered PDU in the APC lineup.
Q: What is the maximum load the AP7553 can handle?
A: The AP7553 is rated for 7680 VA maximum load at 32A / 230V. In practice, size your connected load to no more than 80% of that capacity (approximately 6144 VA) for continuous operation to stay within safe thermal and electrical limits.
Q: Can the AP7553 be mounted horizontally in a rack?
A: The AP7553 is designed as a 0U vertical PDU, intended to mount in the vertical cable management channel of a rack enclosure. It is not designed for horizontal rack-unit mounting. If you need a rack-unit horizontal PDU, a different APC model with a 1U or 2U form factor would be required.
Q: Is the AP7553 compatible with APC UPS units?
A: Yes, the AP7553 can be paired downstream from any UPS with a compatible IEC 309 32A output. The PDU itself provides no battery backup or surge protection — those functions must come from the upstream UPS. Verify that your UPS output rating meets or exceeds the 32A / 7680 VA capacity of this PDU before connecting.
The AP7553 is the unit I reach for when a dense rack needs clean power distribution and there is zero appetite for managed-PDU overhead. That 7680 VA / 32A IEC 309 input is the spec that drives the decision — it's enough headroom to run a fully populated NVR cluster, PoE switch stack, and server row without ever sweating the 80% continuous-load ceiling, assuming your facility circuit is provisioned correctly.
Technical Highlights:
- 24-Outlet Mixed Layout (20xC13, 4xC19): The C13/C19 split on the AP7553 means you can wire in high-wattage storage or UPS bypass on the C19 taps and fill the remaining 20 C13s with 1U servers, switches, and NVRs — no adapters, no compromise on outlet count.
- 7680 VA at 32A / 230V: For a surveillance headend room with 16-channel NVRs, PoE switches, and a management server, this capacity handles the typical combined draw with room to grow. Plan load at 6144 VA (80%) for continuous safe operation.
- 0U Vertical Profile: The PDU drops into the rack's vertical cable channel and disappears — every RU stays available for active equipment. In a 42U rack that's a non-trivial operational advantage during future expansion cycles.
Deployment Considerations:
- The IEC 309 32A input is a hard physical requirement — your facility must have a 32A single-phase circuit with the correct IEC 309 outlet provisioned before this PDU ships. Don't assume a local electrician can swap a 20A outlet overnight.
- The AP7553 is strictly a passive distribution device: no surge suppression, no overcurrent protection beyond the upstream breaker, no monitoring. Upstream UPS protection is not optional in any deployment where equipment downtime has a cost.
This PDU is the right tool for a security operations center or surveillance headend build where rack space is tight, the electrical infrastructure is already at 32A IEC 309, and the priority is maximizing outlet density without adding a network-managed layer to maintain.
