Features: The Industrial USB 2.0 Isolator Hub (HUB23) delivers 480Mbps fast speed data transfer through its three port expansionFeaturing automatic detection for low/full/fast speed connection across multiple USB transmission mode. Engineered with ABS plastic housing and multiple protections (short circuits/ESD/over current), operates driverless for instantly use functionality. Driverless: Not need to install driver, more convenient to use.. Provides short-circuits protections, ESD (electrostatic discharge) protections and over-currents protections.. Portable: small size, easy to carry.. Specifications: Interfaces type: Standard USB-A interfaces standard type c interfaces, supports forward and reverse pluggings. Communication interfaces: USB2.0, automatically detects low-speed, full-speed and fast speed connection. Power supply voltages 5V (from the USB port of the computer host) Isolation voltages: ADUM3165: 3.75kV, power module: 2.5kV Isolated outputs: 500mA@5V ( 2.5W) Operating temperature: - 20°C - 70°C Module size: about 62.32x21x10.7mm/2.45x0.83x0.42in Package Includes: 1PC USB Isolator note: The USB-A port and type c port on the input terminals cannot be used at the same time, and the input voltages cannot exceed 5.5V! The USB-A port and type c port on the input terminals cannot be used at the same time, otherwise the device will not be recognized! The output terminals of type c port can be connection to a 5V power supply, and the input voltages cannot exceed 5.5V. If you need to drive a mobile hard disk, please connect a separate 5V power supply to the output and ensure sufficient voltages through external power supply. After the isolator works normally, there will be a certain amount of heat, which is a normal phenomenon. The USB isolator cannot be used on a win11 computer, otherwise the computer will crash and restart! ! !
