4 Pack Vacuum Cleaner HEPA Filters for Cyclonic Series RO3753EA RO3731EA RO3786EA 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 ensure the computer ,Personal safety.<br> 2. Noise-sensitive areas: Everyone knows that computers are a big noise source. In noise-sensitive areas, we can use this device to isolate the USB interface. Such as high-precision USB data acquisition system, HIFI audio system.<br> 3. USB debugging equipment: such as JTAG/SWD emulators with various USB interfaces, ISP/ASP/IAP/ICP downloaders, etc. When you are often unable to connect or emulate abnormalities during debugging, you can use a USB isolator to try to improve.<br> 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 act as a very USB repeater, and can also isolate the ground pressure difference between upstream and downstream devices.<br> 5. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.<br> Tested and supported devices: Full-speed devices: for USB flash drives, digital cameras, card readers, mobile hard drives, USB shields, USB hubs, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, J-Link, FET430UIF, PICKIT2, XDS100 , LPC-Link, ICD2, USB to serial port (FT232, CP2102, PL2303, CH341 chips).<br> Tested unsupported devices USB wireless network card, some USB3.0 flash drives.<br> Technical index:<br> Compatible with USB2.0<br> ADUM3160 isolation voltage: 2500V<br> Power module isolation voltage: 1500V<br> Supports USB full-spe
