W&T 33204, USB isolator, Industry 4kV
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.
The output voltage from the 4kV Isolator is routed on the galvanically isolated side through a multi-stage L-C filter. The filtered output voltage means the Isolator is also ideal for isolating high-quality USB audio equipment.
Product properties:
