Overview

USB-303 is a USB 2.0 Full Speed(12Mbps) and Low Speed(1.5Mbps) compliant USB hub which isolates between a USB host and two downstream ports with 3000VDC. Each of the two downstream ports are also isolated independently. With USB-303, it can be expected to eliminate ground loops that can cause measurement errors and equipment from surges, common-mode voltage, static discharge, magnetic fields, and radio frequency interference.There is no need to install any drivers. It works with every operating system such as Windows, Linux, Mac OS X.

USB-303

Features

  • Each two downstream port are independent isolation
  • USB host connector which is standard Type B female and have to be connected to a PC or other USB host device
