Safety Instructions 2. Safety Instructions Intended Use The USB Isolator 2 kV HS manufactured by Wiesemann & Theis galvanically isolates Low-, Full- and High-speed USB connections with an isolation voltage of at least 2,000 V. The isolator prevents compensating currents from flowing over the USB line due to potential differences between the connected devices.
Declarations of conformity complete Declarations Conformity vices described in the manual can be found on the corres- ponding datasheet page on the W&T homepage: http://www.wut.de/33003 Subject to error and alteration...
Introduction 3. Introduction USB interfaces in stationary computers unfortunately have the draw- back of having no galvanic isolation for the signal lines. In many applications in the consumer world this limitation is irre- levant, 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 earth conductor.
USB connections. The isolator is simply inserted into the existing USB connection and powered by an external power supply. The isolator of type #33003 isolates Low-, Full- and HighSpeed USB connection galvanically with an isolation voltage of at least 2,000 V The bus speed is detected fully automatically.
#33003 Display elements The isolator features two green LEDs for indicating the correct supply voltage for the isolator. The Power IN LED indicates correct power for the upstream side from the USB host or hub, whereas the Power OUT LED indicates the correct power supply of the downstream side.
#33003 Technical data Isolation voltage: min. 2,000 V DC USB speed: High-Speed (480 Mbit/s) Full-Speed (12 Mbit/s), Low-Speed (1.5 Mbit/s) Power supply: Upstream-Port: USB supplied Downstream-Port: 5 V DC using included power supply Current draw: Upstream-Port: max. 100 mA Downstream-Port: max.
