Panduit PXR1AJF Fault Managed Power System Class 4 Receiver
Overview
The Panduit PXR1AJF is a Class 4 Fault Managed Power System (FMPS) receiver module rated at 1.6 kW and 56 VDC with three inputs and three outputs. Unlike conventional PoE or low-voltage distribution, FMPS technology operates under UL-1400-1 — a standard that permits higher-voltage DC delivery over structured cabling while maintaining personnel safety through continuous fault detection. The PXR1AJF sits at the load end of an FMPS circuit, converting the high-voltage DC feed from a paired transmitter into safe, conditioned power for connected devices. If you are designing a campus-scale IP infrastructure, a large warehouse automation network, or a distributed physical security system where cable runs exceed PoE's practical distance limits, this receiver is a key building block.
The unit measures 9.4 in wide × 4.2 in tall (239 mm × 107 mm), a form factor sized for structured rack or enclosure deployment without consuming excessive panel space. Each PXR1AJF ships as a single unit (package quantity: 1).
Key Features
- Class 4 / UL-1400-1 Listed: UL-1400-1 is the governing standard for FMPS equipment — it defines the fault-managed signaling that lets 56 VDC travel safely over building cabling. Compliance here is not optional; it is what separates a code-compliant FMPS installation from an unapproved high-voltage retrofit. If your AHJ requires listed equipment, this satisfies that requirement.
- 1.6 kW Power Capacity: With 1.6 kW of available output across three ports, the PXR1AJF can simultaneously serve multiple high-draw endpoints — IP cameras with pan-tilt-zoom mechanisms, access control panels with multiple reader heads, wireless access points with active antennas, or industrial sensors. Size your transmitter-to-receiver ratio around this figure during design.
- 56 VDC Output Voltage: FMPS operates at 56 VDC, well above standard PoE (48 V nominal) and substantially above 24 VAC/DC legacy systems. The higher voltage means less resistive loss over long cable runs — practically, you can extend power significantly farther than 802.3bt PoE allows before voltage drop becomes a limiting factor.
- 3 Inputs / 3 Outputs: The three-in, three-out configuration gives the PXR1AJF flexibility in daisy-chain and home-run topologies. Multiple input feeds support redundancy or zone segmentation; three discrete outputs let you isolate loads for independent fault handling — if one output faults, the other two continue operating.
- IEC 62368-1 and IEC 61508 Compliance: IEC 62368-1 covers audio/video and IT equipment safety; IEC 61508 is the functional safety standard for electrical/electronic systems. Dual compliance signals that this unit is designed and validated for environments where safety-integrity levels matter — industrial controls, life-safety adjacent systems, and enterprise IT closets.
- FCC Part 15 Class A / CE / ICES-003 Certified: These emissions certifications confirm the PXR1AJF meets conducted and radiated emissions limits for commercial/industrial environments. Class A (not Class B) means it is rated for professional/commercial deployment, not residential — match your installation environment accordingly.
- RoHS and REACH Compliant: Both certifications are required for EU market entry and are increasingly demanded by enterprise procurement teams for sustainability documentation. If your project has green-build or regulatory requirements, these are pre-verified.
- EN 55032 / EN 55035 Compliance: These European standards address multimedia equipment emissions and immunity respectively — relevant for deployments in mixed IT/OT environments where interference between power and data infrastructure must be controlled.
Integration and Compatibility
The PXR1AJF is part of Panduit's Panduit Fault Managed Power Systems ecosystem and is designed to operate with a compatible FMPS transmitter module. In an FMPS architecture, the transmitter (typically rack- or panel-mounted at the IDF/MDF) sources the 56 VDC Class 4 feed; the PXR1AJF receiver terminates that feed at the device end and provides locally conditioned outputs. Consult Panduit's FMPS transmitter family to identify the correct paired transmitter for your channel count and power budget.
Because the PXR1AJF operates within a standards-based power distribution framework (UL-1400-1, IEC 62368-1, IEC 61508), it can integrate into structured cabling plants that also carry data — a key advantage when retrofitting existing horizontal runs in network infrastructure deployments. Verify that your cable plant meets FMPS minimum conductor requirements before specifying; not all existing Cat cabling is rated for Class 4 currents.
For physical security deployments spanning large facilities — warehouses, campuses, transit terminals — the extended-reach capability of FMPS paired with IP camera endpoints or access control readers eliminates the need for mid-span power injectors or local AC outlets at every device location. This is where FMPS earns its cost justification against conventional PoE switch infrastructure.
Frequently Asked Questions
Q: What voltage and power output does the PXR1AJF deliver?
A: The PXR1AJF operates at 56 VDC and is rated for 1.6 kW total output capacity across its three output ports.
Q: Is the PXR1AJF UL listed?
A: Yes. The PXR1AJF meets UL-1400-1, the standard governing Fault Managed Power System equipment. This is the relevant listing for FMPS Class 4 installations.
Q: What safety and emissions standards does the PXR1AJF comply with?
A: Compliance includes UL-1400-1 (Class 4), IEC 62368-1, IEC 61508, EN 55032, EN 55035, FCC CFR47 Part 15 Class A, CE, CAN ICES-3(A)/NMB-3(A), ICES-003, REACH, and RoHS.
Q: How many inputs and outputs does the PXR1AJF support?
A: The PXR1AJF has 3 inputs and 3 outputs, enabling both redundant feed topologies and independent per-load fault isolation.
Q: Is the PXR1AJF suitable for residential installation?
A: No. Its FCC Part 15 Class A rating designates it for commercial and industrial environments, not residential use.
Q: What are the physical dimensions of the PXR1AJF?
A: The unit measures 9.4 inches wide by 4.2 inches tall (239 mm × 107 mm). Depth data is not published in available specifications.
The PXR1AJF is a receiver module I would specify on any large-footprint physical security project where the cable runs are simply too long for 802.3bt to be practical. At 56 VDC and 1.6 kW across three outputs, a single PXR1AJF can terminate an FMPS feed and simultaneously power several high-draw endpoints — PTZ cameras, multi-reader access control panels, or wireless APs — without requiring local AC drops or mid-span injectors at each location.
Technical Highlights:
- UL-1400-1 Class 4 Listing: This is the listing that makes FMPS installations code-compliant. Without it, running 56 VDC over structured cabling would not pass AHJ inspection in most jurisdictions. The PXR1AJF carries this listing, which matters at submittal time.
- 1.6 kW / 56 VDC Capacity: At 1.6 kW per receiver, you can budget roughly 533 W per output port on average — enough headroom for high-draw PTZ cameras or multi-port PoE injector loads at the device end. Plan your transmitter-to-receiver ratio to avoid oversubscription.
- Dual Functional-Safety Standards (IEC 61508 + IEC 62368-1): IEC 61508 compliance is unusual in power distribution hardware and indicates the unit was designed with functional safety integrity in mind — relevant if your project scope includes life-safety-adjacent systems or requires formal safety documentation for the authority having jurisdiction.
Deployment Considerations:
- Verify that your horizontal cable plant meets FMPS Class 4 conductor requirements before finalizing the design — not all installed Cat cabling supports the current levels that 1.6 kW at 56 VDC implies, and a cable-plant audit mid-project is expensive.
- The FCC Part 15 Class A rating means this unit is not for residential environments — specify it only in commercial, industrial, or enterprise deployments. Class A equipment in a residential install creates both regulatory and liability exposure.
For a transit hub, large warehouse, or multi-building campus security deployment where device locations are fixed but far from the IDF, the PXR1AJF is the receiver-end component that makes a PoE-replacement FMPS architecture viable without rerunning conduit to every endpoint.
