The UHR401 and UHR402 are One and Two Port Ruggedized Isolators. 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. They have 4 kV Isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity. They are also suitable for integration into medical applications requiring 60601-1 certification.
The Heavy Industrial EMC specifications allow these isolators to operate in unfriendly electrical environments -- such as near variable frequency drives, motor control centers, welding, and other large electrical loads.
They are powered from an external 10 to 30 VDC power supply unit. The product comes with an international power supply that has US, EU, and UK blades. There are also power options with a locking barrel plug that can be purchased separately - refer to the ordering information.
The downstream port(s) provides up to 500 mA of power to connected USB devices.
