USBHub3+ is a 9-port USB 5Gbps hub with 2 host connections with a rugged steel housing, ESD protected design and nearly unlimited power output.
- Supports USB hosts and devices up to USB 5Gbps; backwards compatible with USB1, USB2
- Individually enable/disable any of 8 downstream ports
- Measure voltage and current on each downstream port
- Hi-Speed data, SuperSpeed data and power lines can be separately enabled for each downstream port
- Set programmable current limits for each downstream port (up to 4A)
- Dedicated Control Port for software control; independent of the selected upstream port
- Select between two (2) host connections
- All ports support USB link speeds up to 5Gbps
- Detect established link speed on each port: SuperSpeed (5Gbps) or Hi-Speed (480Mbps)
- Supply up to 5A per port; measure up to 4A
- Set enumeration delay for discovery of attached downstream devices
- Backward compatible with USB 2.0 and USB 1.x devices
- Boost USB 2.0 upstream and downstream signal levels
- DIN-rail mountable
- Alternate Euro-style terminal block power input connector
- Certified to +/-15kV ESD strikes (IEC61000-4-2 level 4)
- Overvoltage and reverse current protected Vbus outputs
- Monitor voltage and current on any/all ports
- Maintain selectable control of data, SS lines, power lines for any port
- Enable/Disable any downstream port
Typical Performance Characteristics
Specifications are valid at 25°C unless otherwise noted. Indoor application use only. Sample rates are typically limited by the USB throughput of the host operating system except where bulk capture is supported.

USBHub3c gives developers and engineers full control to validate, control, and test the limits of devices built on the Power Delivery and USB-C specification.
The USBHub2x4 is a 4-port software-programmable 480Mbps (USB 2.0) hub that is designed for demanding industrial environments where advanced control and monitoring of USB ports is required. This is very useful in testing or development environments where standard “always-on” behavior of a consumer-grade USB hub is not desirable.
Automate port switching, hot-plug & type-C connector flips. Monitor Vbus & Vconn voltage & current.
Desktop-style AC to DC power adapter with 12VDC up to 5A (60W) output. Supports universal 100-240VAC input. Recommended for use with Acroname programmable USB hubs.
