polfort Posted February 12, 2010 Report Share Posted February 12, 2010 Hello out there.I am wondering if I could build some device based on optocouplers (or other solution), to seperate a USB device from the PC to make it potential free.Of course the device to be seperated could not be powered via USB. In other case I would be forced to use at least a transformer to power the device through USB.Does anyone know how to do that or has even seen such thing before?Any ideas for a solution?Best regards,polfort Quote Link to comment Share on other sites More sharing options...

esdk Posted July 28, 2010 Report Share Posted July 28, 2010 Hi,You can use a USB2ISO device - that comes complete with BOX, ADUM4160 and isolated 5V power supply. Check it out here: http://electronics-shop.dk/usb-isolatorIt can be used for any full speed USB device - and also some High speed devices that can run at Full speed.Great for removing ground loops and potential of up to 1KV.And the price is kept low at only around $50 for all 3 parts with a 2 year warranty.Best Regards,Sorenelectronics-shop.dk Quote Link to comment Share on other sites More sharing options...
