Liberty AV TeamUp+ Series 4 Port Powered USB 3.0 Commercial Hub - DL-4USB-PHUB

Product Overview

The Liberty AV DL-4USB-PHUB TeamUp+ 4-Port Powered USB 3.0 Commercial Hub is engineered for BYOD conference room deployments where reliable, high-speed USB peripheral connectivity is essential. Designed for AV integration into meeting rooms and huddle spaces, this commercial-grade hub expands a single USB host port into four powered USB 3.0 downstream ports, supporting web cameras, microphones, wireless conference adapters, and other USB devices simultaneously. The metal chassis and integrated mounting brackets allow clean, permanent installation behind displays or under conference tables without cable clutter. No additional drivers or software are required, making it a straightforward addition to any commercial AV system.

Product Description

The DL-4USB-PHUB is part of Liberty AV's TeamUp+ series, built specifically for commercial conference room infrastructure rather than consumer desktop use. Each of the four downstream ports supports USB 3.0 data transfer at speeds up to 5 Gbps, with backward compatibility for USB 2.0 and USB 1.1 peripherals. The hub uses an external power supply rather than drawing power from the host connection, ensuring each downstream port can deliver up to 5V/1A — sufficient for cameras, speakerphones, and other powered USB devices even when no computer is connected.

The charging circuitry supports USB-IF BC 1.2, allowing compatible devices to draw up to 1.5A for faster charging rather than the standard 0.9A. The hub is Gen USB 3.1 compliant and supports SuperSpeed (SS), HighSpeed (HS), FullSpeed (FS), and LowSpeed (LS) traffic across its downstream ports. The industrial-grade metal chassis includes vented slots for passive heat dissipation during continuous operation, and the included mounting brackets with screws allow permanent rack-adjacent or under-table installation. Blue LED status indicators confirm active host connection. For AV integrators building out BYOD meeting room infrastructure, the DL-4USB-PHUB delivers a dependable, commercially supported USB expansion solution.
