KXUSB-150 Keterex

USB-150 Full Speed USB Isolator FEATURES GENERAL DESCRIPTION The Keterex USB-150 Full Speed USB Isolator Isolates a USB Peripheral from a USB Host provides galvanic isolation between a USB peripheral and a USB host. The Isolator is Electrical Isolation up to 2000Vrms connected between the host and peripheral using 5V Isolated Pass-thru Power up to 400mA standard USB cables no other software or configuration is required. In addition, the USB-150 No External Power Supply Required provides an isolated 5V supply to the downstream Supports USB 2.0 Full-Speed Data Rates peripheral device at up to 400mA. Uses Standard USB A/B Cables The USB-150 is used in applications where either the peripheral device operates at a different ground No Configuration Required potential than the host or where supply noise from No Software or Drivers Required the host needs to be eliminated. Any full-speed USB device can be isolated using the USB-150 and Invisible to the Host and Peripheral standard USB cables.
