USB Isolator 1kV

  • WuT USB Isolator 1kV

Galvanic isolation for USB devices

The USB Isolator 33001 galvanically isolates Low-Speed and Full-Speed connections from the USB host and protects the hardware behind it.

Properties

Interfaces:

  • 1 x USB socket, type A
  • 1 x USB male, Type A
  • Galvanic isolation between the ports
    • Isolation voltage min. 1kV DC
    • Do you need greater galvanic isolation? - See Isolator 33204

Management and connectivity:

  • Supports low-speed and full-speed USB devices
  • Solution integrated into USB cable for plug-in

Power supply:

  • External supply voltage for the downstream side
    • enables connection of power-hungry USB devices

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance for industrial environments
    • Low noise emission for residential and business areas
  • 5 year guarantee

Worth knowing

USB interface:
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.
