More Description

The UHR401 is a one port ruggedized isolator that it is 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. The UHR401 has 4 kV isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity. Heavy industrial EMC specifications allow the isolator to operate in unfriendly electrical environments – such as near variable frequency drives, motor control centers, welding, and other large electrical loads. The isolator is powered from an external 10 to 30 VDC power supply (required) and  includes an international power supply that has USA, EU, and UK blades. Downstream port(s) provides up to 500 mA of power to connected USB devices. USB cable also included.
