USB hub Exsys EX-1177-2S 4-port 480 Mb/s with 15 kV ESD protection

Exsys EX-1177-2S is a compact 4-port USB hub that provides USB 2.0 data transfer rates up to 480 Mb/s and integrated 15 kV ESD protection. The hub expands one host USB port into four downstream ports, enabling connection of mice, keyboards, flash drives, printers and other USB peripherals. Its small footprint and bus-powered design make it suitable for both desktop and mobile environments where reliable basic USB 2.0 connectivity and electrostatic protection are required.

Advantages

The hub supports high-speed USB 2.0 transfers up to 480 Mb/s across four ports while maintaining compatibility with USB 1.1 devices. Built-in 15 kV ESD protection helps prevent damage from electrostatic discharge, increasing device reliability in everyday office and home use. The device is bus-powered and does not require an external power supply for typical low-power peripherals, offering a simple plug-and-play experience. Its compact form factor and straightforward connectivity reduce cable clutter and make it easy to reposition between workstations.

Suitable for

• Connecting multiple input devices (mouse, keyboard) to a single USB port
• Expanding a laptop or desktop USB port for flash drives and external storage
• Attaching printers, scanners or other low-power peripherals
• Temporary workstations, meeting rooms and mobile setups

Key specifications

• USB standard: USB 2.0 high-speed, backward compatible with USB 1.1
• Maximum data transfer rate: up to 480 Mb/s
• Number of ports: 4 downstream USB Type-A ports
• ESD protection level: 15 kV
• Power: bus-powered (no external adapter required for low-power devices)
• Form factor: compact, lightweight hub for desktop or mobile use

How to use

Connect the hub's upstream USB cable to an available USB port on your computer. Plug USB devices into the hub's downstream ports; the operating system should detect and configure standard USB peripherals automatically. For high data-rate transfers, connect directly to a USB 2.0 host port to achieve up to 480 Mb/s. Avoid connecting multiple high-power devices simultaneously without an external power source, as the hub is intended primarily for low-power peripherals.

Recommendations

Place the hub on a stable surface and keep connected cables untangled to maintain airflow and prevent strain on connectors. Use the hub for general-purpose expansion of USB ports for input devices, storage media and printers; for bus-powered setups, monitor total connected device current to avoid power limitations. If you require charging or support for multiple high-current devices, consider a powered USB hub.
