1. Working environment with strong electricity and strong interference: some circuits contain strong electricity and strong interference (such as high-voltage electricity, inverter, motor drive, etc.) environment, which involves the connection with the computer. It must be isolated to the computer ,Personal safety.2. Noise-sensitive areas: Everyone knows that computers are a big noise source. In noise-sensitive areas, use this device to isolate the USB interface. Such as high-precision USB data acquisition system, HIFI .3. USB debugging equipment: such as JTAG/SWD emulators with USB interfaces, ISP/ASP/IAP/ downloaders, etc. When you are often unable to connect or emulate abnormalities during debugging, you can use a USB isolator to try to .4. Various industrial USB devices: In the industrial environment, USB devices often crash, such as USB mouse, keyboard, USB to serial port and other communication devices. The USB isolator can effectively reduce the crash and damage probability of these devices in an industrial environment. Sometimes it is necessary to extend the USB cable, the USB isolator can as a USB repeater, and can also isolate the ground pressure difference between upstream and downstream devices.5. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.Tested and supported devices: Full-speed devices: for USB flash drives, digital cameras, card , mobile hard drives, USB shields, USB , AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, , FET430UIF, PICKIT2, XDS100 , -Link, ICD2, USB to serial port (FT232, CP2102, PL2303, CH341 chips).Tested unsupported devices USB wireless network card, some USB3.0 flash drives.Technical :Compatible with USB2.0ADUM3160 isolation voltage: 2500VPower module isolation voltage: 1500VSupports USB full-speed 12Mbps, does not support pure high-speed devicesSupport USB control transmission, batch transmission, interrupt transmission, synchronous/isochronous transmissionPower supply: from the USB port of the computerDrive-free, more convenient to useUse environment: -40 Celsius to 85 CelsiusColour:Transparent BlackMaterial:ABS+metalSize:52.9 x 14.2 x 23.6mmPackage Contents:1 * usb isolatorOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
