PCIe 3.0 x4 expansion card providing four USB 10Gbps Type-A ports with independent power supply for industrial and visual applications.
High-bandwidth machine vision and industrial automation systems often struggle with data bottlenecks when connecting multiple high-resolution cameras or sensors via standard USB interfaces. The LRSU3A42-4A addresses this by delivering dedicated 10Gbps bandwidth per port, ensuring real-time data transmission without latency.
Powered by the ASM3142 controller, this PCIe 3.0 x4 card provides four USB 10Gbps Type-A interfaces, doubling the speed of traditional USB 5Gbps connections. Each port supplies up to +5VDC/900mA with an on-board regulated 5VDC power source, enabling stable operation for power-hungry peripherals while maintaining backward compatibility with USB 5Gbps devices.
Ideal for AI edge computing, medical imaging, and industrial IoT gateways, this card ensures reliable performance under Windows and Linux environments. Its robust ESD protection and wide operating temperature range make it a superior choice for demanding industrial deployments compared to consumer-grade adapters.
Supports USB 10Gbps specification, offering transmission speed twice that of USB 5Gbps for high-bandwidth scenarios.
Expands system connectivity with four simultaneous USB 10Gbps Type-A interfaces for multiple device connections.
Features on-board regulated 5VDC power supply with 1.5A current limit and independent hot-swappable power for each port.
Designed for industrial and visual applications with robust ESD protection and wide operating temperature range.
Compatible with PCIe 3.0/2.0 slots and supports various OS including Windows, Linux, and VMware ESXi.
