描述 Description

Model UHR307 is an industrial-grade, seven-port USB hub with 4 kV isolation. It is designed and tested to meet heavy industrial EMC standards and is UL listed for Class1/Division2 hazardous locations allowing operation where standard office-grade hubs fail – such as near variable frequency drives, motor control centers, welding and other large electrical loads.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. USB cable included.4 kV isolation between the upstream and downstream USB ports protects expensive equipment from dangerous ground loops and helps ensure data integrity. The USB hub is powered from an external 10 to 30 VDC source. Two power connectors are provided – terminal block or threaded/lockable barrel plug. Each downstream port provides up to 500 mA of power to connected USB devices.
