PDS-408G/AC-UK Présentation
A Power over Ethernet (PoE) switch is a networking device that delivers both data and DC power over standard Ethernet cabling (CAT5e/CAT6) to powered devices (PDs) such as wireless access points, IP cameras, and LED luminaires. Within the power-delivery hierarchy, the PDS-408G acts as a Power Sourcing Equipment (PSE) endpoint in the digital building infrastructure, sitting above PoE splitters and PD controllers while below the facility AC distribution.
Key features include a total PoE power budget of 480W, simultaneous 60W delivery on all 8 PoE ports, and up to 90W on any single port for IEEE 802.3bt Type 4 PDs. Automatic PoE power allocation based on the PD device class removes manual configuration. The fully fan-less enclosure enables silent operation in occupied ceiling spaces.
Architecturally, the switch integrates Microchip PoE PSE controller technology with a managed gigabit switching fabric, providing VLAN support, link aggregation, and remote management. Automatic output power based on PD classification ensures each luminaire or terminal receives only the power it requires, maximizing the usable port count within the 480W budget.
Typical applications include digital ceiling PoE lighting systems, where LED fixtures receive power and control data over one cable; wireless access point backhaul in offices and classrooms; and IP surveillance cameras in commercial buildings. The ceiling or communications-room form factor shortens cable runs to fixtures.
Design consideration: the /AC-UK suffix denotes a UK mains plug; select /AC-EU, /AC-US, or /AC-AU variants for other regions. Verify that the 480W budget covers the aggregate PD class demands at full occupancy, and ensure the ceiling ambient stays within the fan-less thermal rating.

Applications typiques
PDS-408G/AC-UK convient pour 6 applications: Digital Ceiling PoE Lighting, Wireless Access Point Backhaul, IP Surveillance Camera Networks, Smart Building / IoT Sensor Hubs, Conference Room and Classroom AV, Communications Room PoE Aggregation.
Digital Ceiling PoE Lighting
The PDS-408G/AC-UK was designed specifically for digital ceiling PoE lighting, where LED luminaires receive both power and control data over a single standard Ethernet cable. Its 480W budget with automatic class-based power allocation lets each fixture draw only its required power - for example, eight 60W fixtures in full-power mode, or more fixtures at lower classes. Because any port can deliver up to 90W under IEEE 802.3bt Type 4, high-output architectural luminaires are supported without a separate power feed. The fan-less, ceiling-mount enclosure removes fan noise from occupied spaces and eliminates a maintenance-bearing failure point. Placed above the ceiling grid, the switch shortens cable runs from the communications room to each luminaire, reducing both copper cost and voltage drop in the PoE cabling.

Wireless Access Point Backhaul
Enterprise 802.11ax/be wireless access points commonly demand 30W to 90W, which maps directly to the PDS-408G/AC-UK's IEEE 802.3af/at/bt compliance. A single switch port can power a full 802.3bt Type 4 access point at 90W, while the automatic PD-class detection reserves only the class-required power, leaving the rest of the 480W budget available for other devices. Deployed in the ceiling near the access points, the switch reduces horizontal cabling back to the IDF and keeps the three uplink ports available for aggregation to the core switch. Because the unit is fan-less, it can be installed in classrooms, offices, and conference rooms without acoustic impact, and managed features such as VLANs let the WLAN traffic be segmented from the lighting or camera VLANs on the same infrastructure.
Recommandé
IP Surveillance Camera Networks
IP cameras, including PTZ models with heaters and IR illuminators, draw between 10W and 60W - well within the PDS-408G/AC-UK's per-port capability. The switch powers up to eight cameras at 60W each simultaneously in full-power mode, with class-based allocation ensuring fixed dome cameras do not consume budget needed for PTZ units. Managed operation supports dedicated surveillance VLANs and link aggregation on the three uplink ports for bandwidth headroom during multi-stream video recording. The ceiling placement shortens runs to corridor and entrance cameras, and the fan-less design avoids introducing noise or dust-moving airflow into clean interior environments. As with lighting deployments, installers should verify that the sum of all connected camera classes remains within 480W under worst-case simultaneous operation.

Smart Building / IoT Sensor Hubs
Digital ceiling deployments increasingly include occupancy sensors, environmental sensors, badges, and controllers that use Ethernet for both connectivity and power. The PDS-408G/AC-UK's automatic power allocation by PD class suits these low-power endpoints: Class 1-3 devices reserve only a few watts, so a single 480W switch can serve many sensors alongside a handful of high-power luminaires or access points. Remote management, VLAN support, and link aggregation allow IT and facilities teams to segment building-automation traffic, monitor the switch from a central controller, and uplink to the BMS backbone. Because the enclosure is fan-less and rated for ceiling or communications-room placement, it can sit directly in the plenum space near the sensor clusters it serves, simplifying structured-cabling design in retrofit and new-build smart buildings.

Conference Room and Classroom AV
Modern meeting spaces combine PoE-powered displays, room controllers, cameras, and wireless presentation gateways on a single structured-cabling infrastructure. The PDS-408G/AC-UK's mix of 90W-per-port capability and managed uplinks fits this profile: room controllers and cameras draw class-based power automatically, while the three uplink ports aggregate AV, control, and corporate VLAN traffic to the core. Silent fan-less operation is a decisive advantage in conference rooms and classrooms where switch fan noise would otherwise require the unit to be relocated to a distant closet, lengthening cable runs. Deployed above the room ceiling or in the local comms niche, the switch keeps all room endpoints on one powered cable type, cutting installation time versus separate mains drops for each device.
Recommandé
Communications Room PoE Aggregation
Beyond the ceiling, the PDS-408G/AC-UK is specified for deployment in communications rooms, where it acts as a dedicated 480W PoE aggregation layer. In this role it consolidates PoE feeds from a main switch: the three uplink ports carry data while the eight PoE ports concentrate power delivery for high-draw devices such as 802.3bt radios or multi-radio enclosures. Offloading PoE from the core switch protects its power budget and avoids midspan injector sprawl. Managed features - VLANs, link aggregation, and remote management - integrate it cleanly into existing enterprise hierarchies, and the fan-less architecture suits acoustically sensitive or low-maintenance closets. Engineers should confirm the AC circuit and the communications-room ambient temperature support continuous 480W delivery in the fan-less thermal envelope.

Principaux différenciateurs
- 90W per-port headroom on any port (vs PDS-408G/AC-US)
- Full-power mode across all ports (vs PDS-408G/F)
- Fan-less silence in occupied spaces (vs Conventional managed switches with fans)
Notes de conception
Budget the 480W envelope against aggregate PD class demand, not port count. Per the Microchip datasheet, full-power mode provides 60W on all 8 PoE ports simultaneously; any single port can reach 90W under IEEE 802.3bt Type 4, but simultaneously requesting 90W on multiple ports exceeds the budget. Rely on the switch's automatic class-based allocation, and verify worst-case simultaneous draw of luminaires with heaters or access points at full radio load before finalizing the deployment.
The PDS-408G is fan-less, so all heat from up to 480W of PoE delivery plus internal conversion losses must dissipate passively through the enclosure. When installing in a ceiling plenum, avoid enclosing the unit in sealed junction boxes or wrapping it in insulation, and confirm the ceiling ambient stays within the datasheet operating range. In communications rooms, ensure rack or shelf ventilation. Estimated derating: reduced airflow environments effectively increase enclosure temperature, so leave clearance around the chassis.
Order the correct regional variant: /AC-UK is the UK-plug version; /AC-EU, /AC-US, and /AC-AU ship with EU, US, and AU cords respectively, and /AC has bare AC input per the datasheet ordering table. Also note that PoE cabling length and gauge affect delivered power - long or thin CAT5 runs increase IR drop, so for 802.3bt high-power ports near 90W, use CAT6 or better and keep runs within standard 100m Ethernet limits.
