Middle Atlantic PDX-915R NEXSYS 9-Outlet Rackmount PDU with Multi-Stage Surge Protection

Overview

The Middle Atlantic PDX-915R is a rackmount power distribution unit from the NEXSYS series, built for AV and security integrators who need clean, protected power delivery in rack-dense environments. With nine NEMA 5-15R outlets, 120V/15A capacity, and multi-stage series surge protection that responds in under one nanosecond, the PDX-915R is engineered for behind-the-display installations, digital signage racks, and AV control rooms where unprotected power is not an option. Its shallow 9–15 inch depth compatibility makes it a practical fit for a wide range of standard and shallow-format rack enclosures without requiring a custom shelf solution.

The PDX-915R sits within Middle Atlantic's power management lineup, a product family that has long been the integrator standard for structured AV and security rack builds. For those speccing a full rack system, pairing this unit with a compatible rack enclosure ensures depth alignment and clean cable routing from the start.

Key Features

• 9 NEMA 5-15R Outlets: Nine outlets give you enough feeds to power a mixed AV/security rack — displays, media players, network gear, and control processors — without daisy-chaining strips or introducing single points of failure. NEMA 5-15R is the standard 15A receptacle, compatible with virtually every commercial AV and security device.
• Multi-Stage Series Surge Protection: Single-stage surge protectors absorb a hit and degrade silently — you won't know protection is gone until the next strike. Multi-stage series architecture distributes surge energy across successive stages, providing more consistent clamping performance and longer service life in environments with recurring transient events (think signage racks near HVAC breakers or outdoor displays on shared circuits).
• Sub-Nanosecond Response Time: At under 1 nanosecond, the PDX-915R reacts faster than any transient can build to a damaging level. For sensitive processors and media players where even microsecond-level spikes can corrupt firmware or storage, this response speed is the spec that actually protects the equipment — not just the marketing claim that surge protection is present.
• 120V / 15A Input: Designed for standard North American circuits. The 15A rating matches the most common commercial breaker size, so the PDX-915R installs directly on any standard circuit without load calculations or panel upgrades. Total rack load should be kept under 1,440W (80% of 1,800W capacity) for continuous draw.
• Rackmount Form Factor, 9–15 Inch Depth Compatibility: The adjustable depth range from 9 to 15 inches means this unit installs in both full-depth server racks and the shallower AV/signage enclosures common in retail and hospitality deployments. Shallow racks are a frequent pain point for power management — the PDX-915R is explicitly rated for them.
• Passive Cooling with Vent Patterns: No fans means no fan noise, no fan failures, and no additional heat load introduced into the rack. Vent patterns handle convective airflow passively — the right call for digital signage and presentation environments where acoustic performance matters.
• Purpose-Built for Behind-the-Display and Digital Signage Applications: The NEXSYS PDX-915R is not a generic strip bolted to a rack shelf. It is sized, protected, and vented specifically for the power profile of commercial display systems — where multiple low-draw devices share a single circuit and surge events are a known operational risk.

Integration and Compatibility

The PDX-915R is designed for rack-based AV and security installations. Its NEMA 5-15R outlets accept standard 15A plugs used by virtually all commercial displays, media servers, NVRs, and AV processors. The 9–15 inch depth compatibility means it integrates with the majority of rackmount PDU and power management configurations without adapter hardware. For integrators building out digital signage or security command centers, the passive cooling approach also avoids introducing fan noise into presentation or monitoring environments where ambient sound levels matter.

If your rack design calls for higher amperage circuits, higher outlet counts, or metered/monitored power distribution, review the broader Middle Atlantic NEXSYS power management family for models with 20A inputs or switched outlet control. For a full rack build, consult a rack accessories resource to confirm enclosure depth and rail compatibility before ordering.

Frequently Asked Questions

Q: What is the maximum load capacity of the PDX-915R?

A: The PDX-915R operates on a 120V/15A circuit, providing a maximum capacity of 1,800W. For continuous loads, stay at or below 80% — approximately 1,440W — to comply with NEC guidelines and avoid nuisance tripping.

Q: What type of surge protection does the PDX-915R use?

A: The PDX-915R uses multi-stage series surge protection with a response time of under one nanosecond. This architecture distributes transient energy across successive protection stages, providing more durable protection than single-stage designs that degrade after each event.

Q: Will the PDX-915R fit in a shallow rack enclosure?

A: Yes. The PDX-915R is rated for rack depths from 9 to 15 inches, making it compatible with both standard full-depth racks and the shallower enclosures common in behind-the-display and digital signage installations.

Q: Does the PDX-915R require active cooling or a fan?

A: No. The PDX-915R uses passive cooling via integrated vent patterns — no fan is required. This eliminates fan noise and reduces the risk of cooling-component failure in long-running installations.

Q: What outlets does the PDX-915R provide, and how many?

A: The PDX-915R provides nine NEMA 5-15R outlets, the standard 15A receptacle used by virtually all commercial AV, display, and security devices in North America.

Q: Is the PDX-915R suitable for NVR and security equipment racks, not just AV?

A: Yes. While the PDX-915R is listed for behind-the-display and digital signage applications, its rackmount form factor, nine outlets, and multi-stage surge protection make it equally appropriate for security equipment racks housing NVRs, switches, and access control hardware on standard 15A circuits.
