Middle Atlantic PDX-615C NEXSYS Compact Power Distribution Unit
The Middle Atlantic PDX-615C is a compact, behind-the-display power distribution unit from the NEXSYS series — purpose-built for digital signage enclosures, AV equipment bays, and commercial installations where depth is constrained and clean, protected power matters. At just 2 inches deep, the PDX-615C fits flush behind displays and inside shallow enclosures that full-size rack PDUs simply won't clear. If you're deploying interactive kiosks, digital menu boards, or surveillance monitor stations, this is the unit that disappears behind the hardware and quietly handles the electrical housekeeping.
Key Features
- Six NEMA 5-15R Outlets at 1440W Total Capacity: Six receptacles on a single unit eliminates the need for multiple power strips or adapters in tight bays. At 1440W total capacity, you have enough headroom to power a commercial display, a media player, and ancillary devices simultaneously — without chaining strips or tripping a breaker mid-shift.
- Multi-Stage MOV Surge Protection with Sub-Nanosecond Response: The MOV (Metal Oxide Varistor) surge suppression responds in under 1 nanosecond — fast enough to clamp a voltage spike before it reaches sensitive display electronics or embedded media players. Multi-stage design means the surge is handled in layers, not by a single component that degrades silently after one large event.
- Overvoltage and Undervoltage Protection (100V–135V Window): The PDX-615C actively monitors line voltage and disconnects loads when voltage drops below 100V or climbs above 135V. Undervoltage is the silent killer for power supplies — it causes components to run hot and fail early. This gate prevents brownout damage in facilities with inconsistent utility power.
- Integrated Circuit Breaker: An onboard circuit breaker handles overcurrent conditions without requiring a facility electrician or a fuse replacement. When a fault occurs, you reset at the unit — no hunting for fuses, no service call. Relevant in any deployment where downtime is measured in lost revenue per minute.
- EMI/RFI Filtering: The built-in EMI/RFI filter suppresses high-frequency electrical noise on the line before it reaches your equipment. In environments with motor loads, HVAC cycling, or other inductive devices on the same circuit, this keeps display controllers and media players from exhibiting erratic behavior traced back to dirty power.
- IEC C14 Input: The IEC C14 inlet means you connect via a standard IEC C13-to-C14 power cord — the same connector type used on rack-mount UPS units and most commercial AV gear. Clean integration into any UPS-backed circuit without needing a NEMA adapter.
- NEMA 5-15P Plug — Standard 120V Circuit Compatibility: Ships with a NEMA 5-15P plug, compatible with any standard 15A/120V outlet. No special circuit requirements, no electrician needed for installation — plug-and-play deployment in any commercial space.
- 2-Inch Depth Form Factor: The 2-inch depth is the critical spec for behind-the-display mounting. Most commercial flat panels have 2–4 inches of clearance between the rear panel and a wall mount. The PDX-615C was engineered for exactly this constraint — enabling clean, cable-managed power distribution without the unit protruding beyond the display edge.
Integration and Compatibility
The PDX-615C is drawn from Middle Atlantic's Middle Atlantic power and AV infrastructure catalog, designed to pair with their line of display mounting systems and enclosures. As part of the broader power distribution unit category, it fits scenarios ranging from single-display retail kiosks to multi-screen command center builds. The IEC C14 input integrates directly with UPS systems — connect it downstream of an APC or CyberPower unit to layer battery backup onto the surge and conditioning protection already built in. For high-density digital signage rollouts, pair with a structured AV infrastructure solution that includes cable management and mounting hardware to complete the installation. Review our power planning guide for sizing guidance when stacking multiple display circuits on a single UPS branch. If your installation requires rack-mounted power conditioning in a full-depth enclosure, compare against Middle Atlantic's rack PDU family before specifying — the PDX-615C trades rack-mounting flexibility for its slim behind-panel form factor.
Frequently Asked Questions
Q: What is the maximum load the PDX-615C can handle?
A: The PDX-615C is rated for 1440W total capacity across all six outlets. At 120V, that translates to 12 amps — keep total connected load below this threshold to avoid tripping the onboard circuit breaker.
Q: What type of surge protection does the PDX-615C use?
A: The PDX-615C uses multi-stage MOV (Metal Oxide Varistor) surge protection with a response time of under 1 nanosecond. This multi-stage design provides layered suppression rather than relying on a single MOV that can degrade after a major transient event.
Q: Does the PDX-615C protect against low voltage (brownouts)?
A: Yes. The unit includes undervoltage protection that disconnects loads when line voltage drops below 100V, protecting connected equipment from the thermal stress and early failure associated with sustained low-voltage operation.
Q: What power cord does the PDX-615C use for the input connection?
A: The PDX-615C uses an IEC C14 inlet, which accepts a standard IEC C13-to-C14 power cord. This is the same connector type found on most UPS systems and commercial AV equipment, making integration straightforward.
Q: Can the PDX-615C be mounted behind a flat-panel display?
A: Yes — the 2-inch depth is the core design intent. The PDX-615C is specifically engineered for behind-the-display and digital signage applications where enclosure depth is limited. Verify your specific mount's clearance before installation.
Q: Does the PDX-615C include EMI filtering?
A: Yes. The PDX-615C incorporates EMI/RFI filtering to suppress high-frequency electrical noise from the line before it reaches connected equipment — useful in commercial environments where HVAC, motor loads, or other inductive devices share the circuit.
The spec I keep coming back to on the PDX-615C is that 2-inch depth — it sounds trivial until you're on-site trying to fit a power solution behind a 55-inch commercial display mounted on a VESA arm with 3 inches of wall clearance. Most PDUs won't clear. This one does, and it brings 1440W of surge-protected, voltage-gated power with it rather than forcing you to fall back to an unprotected power strip.
Technical Highlights:
- Sub-1ns MOV Surge Response: At under 1 nanosecond clamping time, the multi-stage surge suppression in the PDX-615C acts faster than a standard single-stage MOV — relevant when the transient is a sharp spike from a nearby inductive load switching on the same panel.
- 100V–135V Operating Window: The active voltage gate disconnects loads outside this range. In commercial buildings with aging electrical infrastructure, brownouts in the 105–110V range are common — this gate catches them before display power supplies start running hot.
- IEC C14 Input Integration: The C14 inlet means you drop this directly downstream of any UPS with a C13 output. No adapters, no NEMA converters — clean daisy-chain from your battery backup into clean, filtered, protected distribution at the display.
Deployment Considerations:
- Verify total connected wattage stays under 1440W (12A at 120V) before commissioning. A 65-inch commercial display pulling 250W plus a media player at 50W plus a receiver leaves significant headroom — but stacking multiple screens on a single PDX-615C will hit the breaker.
- The PDX-615C carries no isolated ground — if your installation requires ground isolation for noise-sensitive audio or broadcast equipment, look at a higher-spec unit in the Middle Atlantic lineup with that feature explicitly listed.
This unit earns its place in any managed digital signage rollout — retail end-caps, quick-service restaurant menu boards, lobby directories — where the install crew needs protected, code-clean power that disappears behind the hardware and doesn't require a return visit to reset a blown fuse.
