The UPort® 400A Series industrial-grade USB 3.2 hubs can expand an USB port into 4 or 7 USB ports. The hubs are designed to provide true USB 3.2 Gen 1 SuperSpeed 5 Gbps data transmission rates through each port, even for heavy-load applications. The UPort® 400A has been awarded the USB-IF SuperSpeed certification, which is an indication that the product is a reliable high-quality USB 3.2 hub. In addition, the hubs are fully compliant with the USB plug-and-play spec and provide full 900 mA power per port, ensuring that your USB devices function properly. The UPort® 400A hubs support a 12 to 48 VDC power range, which make them ideal for mobile applications. Externally powered USB hubs are the only way to guarantee the broadest compatibility with USB devices.

USB-IF Certification

The UPort® 400A USB 3.2 industrial-grade USB hubs have been awarded the USB-IF (USB Implementers Forum) certification. USB-IF verifies a number of strict electrical requirements for the SuperSpeed USB operation of USB hubs designed as per the USB 3.2/2.0 specification. This means that the UPort® 400A supports SuperSpeed USB 3.2 Gen 1 for up to 5 Gbps USB transmission, is fully compliant with interoperability requirements, has enough power for devices to function, and facilitates a smooth transition back to SuperSpeed operation from the suspended state.

ESD Level 4 Protection

Electrostatic discharge (ESD) could be as severe as having more than 1,000 volts of ESD with a high rise-time (dv/dt) breaking through the junction layer of protective devices. In order to avoid serious damage, Moxa’s UPort® 400A Series USB hubs provide ESD Level 4 (contact 8 kV, air 15 kV) protection, which increases the quality and value of the user’s end product.

USB Cable With a Firmer Connector

UPort® 400A comes with a USB cable that has a latch and screw lock for a more secure connection between the UPort and your computer.
