Introduction
The industrial-grade USB 3.2 hubs of the UPort 400A series can expand one USB port into 4 or 7 USB ports. The hubs are designed to deliver true USB 3.2 Gen 1 SuperSpeed data transfer rates of 5 Gbps through each port, even under heavy-load applications. The UPort 400A has been awarded the USB-IF SuperSpeed certification, indicating that it is a reliable, high-quality USB 3.2 hub. Additionally, the hubs comply with the USB Plug-and-Play specification and provide a full 900 mA of power per port, ensuring the seamless operation of your USB devices. The UPort 400A hubs support a power supply range of 12 to 48 VDC, making them ideal for mobile applications. Externally powered USB hubs are the only way to ensure maximum compatibility with USB devices.

USB-IF Certification
The industrial-grade UPort 400A USB 3.2 USB hubs have been awarded USB-IF (USB Implementers Forum) certification. USB-IF tests a range of stringent electrical requirements for SuperSpeed USB operation of USB hubs developed according to the USB 3.2/2.0 specification. This means that the UPort 400A supports SuperSpeed USB 3.2 Gen 1 for USB transfers of up to 5 Gbps, fully meets interoperability requirements, provides sufficient power for functioning devices, and allows for a smooth transition from sleep mode back to SuperSpeed operation.

ESD Protection Level 4
Electrostatic discharges (ESD) can be severe enough that more than 1,000 volts of ESD with a high rise time can breach the protective layer of safeguards. To avoid serious damage, the USB hubs of the UPort 400A series from Moxa offer Level 4 ESD protection (Contact 8 kV, Air 15 kV), which ensures quality and...
