[USB-303] 2 Port USB Isolator HuMANDATA LTD.

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.
