Industrial grade USB HUB, extending 4 x USB 2.0 ports, suitable for industrial/office environments with higher-level device requirements.


  • 4 x extended USB ports, compatible with USB 2.0 / 1.1.
  • Industrial grade HUB chip.
  • ESD protection for each USB port, preventing electric surge damage and data loss.
  • Over-voltage protection, effectively preventing other high-voltage power inputs from damaging the connected devices.
  • Multiple protection circuits: over-voltage, over-current, short circuit, over-temperature, reverse current, under-voltage lock-out, 8KV ESD protection, filtering protection, etc.
  • LED indicators for monitoring operating statuses of power supply and USB ports.
  • Industrial grade metal case, rugged & durable, with mounting holes for easy installation.


  • Standard: USB2.0
  • Data rate: up to 480Mbps
    • Operating voltage: 5V
    • Connector: USB-A
    • Operating voltage: 5V@Imax:1.2A①
    • Connector: USB-A
  • External Power:
    • Power supply voltage: DC 5V②
    • Connect: DC jack
  • Operating environment: -40°C ~ 85°C

①: up to 1.2A Max output current for each USB port, when there's enough power input.
②: comes with a 5V 2A power supply, it is recommended to use another 5V 4A or above power supply for higher USB loads.

About Using

The USB HUB 4U is plug-and-play for most of the PC or SBC.

  • The HUB can only support 5V power input, if the supply voltage is too high, the protective circuit will cut off the power directly.
  • This HUB has four USB output ports and supports up to 1.2A Max output current for each USB port. If the working current of the USB device is larger than 1.2A, the short-protective circuit will be activated and you need to remove the USB device to restore it.
  • The working temperature of the HUB is -40°C ~ 85°C, with no condensation. Note that this device is not waterproof.
  • LED1 ~ LED4 is the working indicator of every USB port, the indicators light if the USB ports are connected and enumerated successfully.
  • The red PWR LED is the power indicator of the USB HUB.



Please check if you have connected the correct power adapter for the USB HUB and check if the USB device works normally first by connecting it to another PC directly. If the USB device works normally with another PC, please check if your PC has a pre-installed USB driver.




The power consumption is about 10mA.
Without an external power supply and connected to USB 2.0, the maximum output current is about 490mA.



You can also connect it to a USB3.0 interface, which is about 5V 1A and has a relatively strong power supply capacity, or it is also supported if it connects to a larger current, as long as the voltage is 5V.
