Industrial-grade 4-port USB 3.0 adapter with independent controllers for maximum bandwidth.
Connecting multiple high-speed imaging or storage devices often leads to bandwidth bottlenecks when sharing a single controller. The LRSU9A72-4A solves this by providing dedicated processing power for each port, ensuring stable data transfer for critical industrial tasks.
Equipped with four independent NEC upD720202 host controllers and a PCIe 2.0 x4 interface, this adapter delivers up to 5 Gbps bandwidth per port independently. This architecture eliminates the performance drop common in multi-port cards, while the on-board regulated 5V DC supply supports configurable 900mA/1500mA current limits for reliable device operation.
Ideal for machine vision systems and high-speed data logging under Windows or Linux, the LRSU9A72-4A ensures robust connectivity. Its industrial-grade design guarantees stable power delivery and consistent throughput for demanding environments.
Four independent NEC upD720202 USB 3.0 Host Controllers ensure maximum per-port performance without degradation.
Delivers up to 5 Gbps bandwidth for each port independently via PCIe Gen2 x4 interface.
On-board 5V DC regulated power supply with user-configurable 900mA/1500mA current limit.
Supports Windows XP/7/8 and Linux, designed for industrial and vision applications.
