1. Onboard 3-way USB expansion port, compatible with USB 2.0/1.1 transmission. Onboard RTL8152B Ethernet chip, lead out RJ45 network port, 10/100M adaptive 2. Using industrial- HUB chip, using MTT technology, the simultaneous use of USB is more stable and . Each USB port has ESD protection, the device connection is from power surge damage and data loss 3. The on-board -capacity electrolytic capacitor can effectively make the power supply output of the USB port more stable. The on-board overvoltage protection circuit can effectively prevent the equipment from being damaged due to the access of other high-voltage power sources. 4. Onboard multiple protection circuits: overvoltage protection, overcurrent and short circuit protection, overtemperature protection, reverse current protection, undervoltage lockout, 8KV ESD protection, filter protection, etc. 5. There are multiple LED indicators on the board, which is convenient to check the working status of the power supply, network port and USB interface. Industrial- metal shell, sturdy and durable, reserved screw holes for easy installation and fixationSpecification:USB interface: USB2.0 interface*3, theoretically up to 480MbpsNetwork port: 10/100M adaptive USB HUB input: working voltage: 5V; interface form: USB-B type interfaceUSB output: working voltage: 5V@lmax 1.2A; interface form: USB-A type interfaceExternal power supply: power supply voltage: DC 5V; interface form: DC power supply terminal: Compatible with: OS (version 8.6 and above), Linux ( version above 2.4.20), Windows11/10/8.1/8/7/XPProduct size: 86 x 47.8 x 27.6mmPlug Type:US Plug,it applies to Canada, ,Mexico, Thailand, the , the Philippines,Taiwan and so on.color:BlackMaterial:MetalPackage Contents:1 x USB hub converter1 x USB cable (1.2m)1 cord (US plug)Only the above package content, other are not included.
