Why you need this USB isolator Protect your computer from strong electrical noise and interference in harsh environments such as voltage systems, inverters, and motor drives by isolating the USB connection. Improve performance in noisesensitive applications by isolating the USB interface, helping maintain data integrity for precision devices like precision USB data acquisition systems and HIFI audio systems. Reduce crashes and damage to USB devices in industrial settings. It effectively lowers the risk for devices such as USB mice, keyboards, and USBtoserial adapters. It can also extend USB cables while acting as a USB repeater and isolating ground differences between upstream and downstream devices. What it does Provides galvanic isolation between the upstream USB host (computer) and downstream USB devices, protecting sensitive electronics from voltage spikes and ground loops. Acts as a USB repeater to extend cable length when needed, while maintaining electrical isolation between sides. Core features and attributes Function: USB isolation with groundpotential difference mitigation to improve reliability and safety of USB links. Compatibility: Works with common USB devices including mice, keyboards, USBtoserial adapters, USB data acquisition systems, and JTAG/SWD emulators, ISP/ASP/IAP downloaders, and other debugging interfaces. Size and form: Compact, designed for desktop and cabinet installations, suitable for integration into both test benches and production environments. Material and construction: Robust housing for reliable operation in diverse work environments. Performance: Reduces device crashes and connection anomalies in challenging environments and improves stability for debugging equipment. Use scenarios and applications Harsh electrical environments: Install between the computer and sensitive USB devices in areas with strong electrical noise or interference (voltage lines, inverters, motor drives) to protect the PC and maintain USB functionality. Noisesensitive systems: Use in precision USB data acquisition setups or HIFI audio systems to isolate the USB data path from noise and grounding issues. Industrial and debugging setups: Deploy to stabilize USB peripherals (mouse, keyboard, USBtoserial adapters) on factory floors or during development. Also useful when debugging equipment such as JTAG/SWD emulators, ISP/ASP/IAP downloaders, where intermittent connections or emulation abnormalities are common. Important notes The device isolates the USB connection to reduce ground differences and electrical noise, while allowing standard USB devices to operate more reliably in difficult environments. It is suitable for installations that require cable extension without compromising isolation and USB integrity.
