SEGGER USB Hub — Power supply and connector
The SEGGER USB Hub is a seven-port, industrial-grade USB hub that provides power to Flasher Compact units and connects them to the Flasher Hub.
Overview
The SEGGER USB Hub is a 7-port USB2.0 full speed USB hub designed to meet industrial standards in production environments.
It is tested according to EN 61326-1, EN 55011 and EN 55024/55035. These standards are valid for electrical equipment for measurement, control and laboratory use.
Key features
- Upstream port isolation (basic isolation, 3 kV DC for 1 s)
- Single downstream port overload limit
- High retention USB-B upstream and USB-A downstream ports
- Screwable power supply plug (solid / stranded wire, section 0.2-3.3 mm2)
- Power supply 8-30 VDC, reverse polarity protected
Use case
Gang programming
Gang programming is used to increase the throughput of a programming station. The SEGGER USB Hub provides a tested USB Hub to simply expand the number of available USB ports to connect up to 24 Flasher Compacts with a Flasher Hub.

Safety considerations
The SEGGER USB Hub provides basic isolation only. It is not for use with hazardous voltages without taking further protection measures to avoid risk of electrical shock and fire.
The USB Hub provides basic isolation to withstand high voltages as mentioned in the resp. technical data section. To protect people when dealing with potential hazardous voltage it is mandatory to have a second protection measure in place in case the first insulation barrier fails. This is called double or reinforced isolation. How this double isolation is achieved depends on the use case or application setup.
Check the local safety directives for your country to make sure all requirements are met.
