In sensitive electronic environments, not all USB hubs are created equal. Introducing the Sipolar AT-4A20M3, a 4-port USB 2.0 hub engineered with one critical differentiator: full electrical isolation. Designed for professionals who work with high-voltage equipment, sensitive instruments, or in electrically noisy settings, this hub acts as a reliable safeguard for both your host systems and connected devices. Why Isolation Matters Standard USB hubs create a direct electrical path between your computer and all downstream devices. This connection, while efficient for everyday use, carries significant risks in lab, industrial, or development settings. A voltage spike, ground loop, or EMI (electromagnetic interference) from one connected device can travel back through the hub, potentially damaging your computer’s motherboard, USB ports, or other valuable hardware. The AT-4A20M3 solves this problem at its core. It incorporates built-in isolation transformersthat completely break the direct electrical connection between the upstream (host) and downstream (device) ports. Data and power are transmitted via magnetic coupling, creating a “3KV electrical barrier” that blocks dangerous voltages and noise while maintaining seamless USB 2.0 communication at speeds up to 480 Mbps. Key Features & Specifications • Robust Isolation: 3KV isolation for both USB data lines and power lines, ensuring comprehensive protection. • Wide Voltage Input: Supports DC 9V–24V input via a secure 2-pin lockable terminal with anti-reverse protection. • Flexible Power Modes: ◦ Bus-Powered Mode: Can operate without an external adapter, providing up to 0.6A total across four ports for low-power peripherals. ◦ Externally Powered Mode: With an external power supply, each port delivers up to 1A, with a total output not exceeding 20W for demanding devices. • Enhanced Protection: Features output over-current protection, short-circuit protection, and high-level ESD protection (Contact: 6KV; Air: 8KV). • Universal Compatibility: Works seamlessly with Windows XP through 11, macOS 10.12+, and major Linux distributions like Ubuntu 16.04+. • Durable Design: Built for challenging environments with an operating temperature range of -25°C to 80°C and support for installation via mounting ears or DIN rail. Ideal Applications The Sipolar AT-4A20M3 is the preferred choice for scenarios where equipment protection and signal integrity are non-negotiable: • Laboratory & Test Benches: Protects PCs and data acquisition systems when connecting to instruments prone to sudden voltage transients (e.g., motor controllers, RF equipment). • Industrial Control Systems: Isletes PLC programming stations and HMIs from electrical noise generated by heavy machinery, drives, and power supplies on the factory floor. • Medical & Diagnostic Equipment: Helps maintain reliable data transfer and protects sensitive host computers from potential electrical faults in connected devices. • Electronics Development & Debugging: Safeguards expensive host computers and programmers (like ARM debuggers) when testing or debugging boards with high-voltage sections, preventing costly damage from accidental leakage or faults. Engineered for Reliability Beyond protection, the AT-4A20M3 ensures stable data transmission by filtering out electromagnetic interference. Its compact, industrial-grade housing (93 x 70 x 34.8 mm) is made for continuous operation in diverse conditions. Don’t let an unexpected surge compromise your critical work or expensive equipment. The Sipolar AT-4A20M3 Isolated USB Hub provides the essential defense layer your setup needs. Interested in integrating reliable, isolated connectivity into your systems?
