The UHR207 and UHR307 are Industrial Grade Seven Port USB Hubs. Model UHR307 includes 4 kV isolation. They are designed and tested to meet heavy industrial EMC standards. High retention USB connectors hold standard USB cables tight and are perfect for high vibration applications - requiring up to 3.2 lbs-force to disconnect them.
4 kV Isolation (UHR307) between the upstream and downstream USB ports protects expensive equipment from dangerous ground loops and helps ensure data integrity.
They arpowered from an external 10 to 30 V DC source. Two power connectors are provided - terminal block or threaded/lockable barrel plug. Refer to ordering information for power supply recommendation. Each downstream port provides up to 500mA of power to con nected USB devices.
The Heavy Industrial EMC specifications allow these hubs to operate where standard office grade hubs fail - such as near variable frequency drives, motor control centers, welding, and other large electrical loads.
