W&T USB isolator, 1kV
Galvanically isolated connection of two USB devices
Isolation voltage min. 1000 Volts DC
Supports low-speed and full-speed USB devices
Solution integrated into USB cable for plug-in
Power supply included
External supply voltage for the downstream side enables connection of power-hungry USB devices
Conforms to standards both in office and industrial environments:
Increased noise immunity for industrial areas
Stricter noise emission for residential and commercial areas
USB interfaces in stationary computers unfortunately have the basic drawback of having no galvanic isolation for the signal lines. In many applications in the consumer world this limitation is irrelevant, since the USB devices connected to the PC are generally supplied through the bus and do not have any reference to a second ground or to the ground conductor. In the areas of measurement reading, process control or for example medical technology, galvanic isolation of the connected devices is mandatory in order to prevent ground loops on the USB line. To this end W&T offers a family of USB isolators which differ in their mechanical configuration and in their supply voltage and amount of isolation voltage.
