- Page 3 W&T USB Isolators 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.

USB Isolators USB Isolator, 1kV, #33001 Function The Wiesemann & Theis USB-Isolator #33001 provides galvanic isolation for low-speed and full-speed USB connections with an isolation voltage of at least 1000V DC. The Isolator eliminates ground loops and prevents current from flowing between the connected devices and the supply lines of the USB caused by potential differences. -
