DFRobot 2500V Industrial USB 2.0 Isolator - 480Mbps

Protect sensitive USB ports from external power interference and signal noise with this industrial-grade USB 2.0 isolator. It uses magnetic isolation to create an electrical barrier between connected USB devices, helping to reduce ground loop issues and protect development boards, motherboards and other critical equipment.

The isolator is compatible with standard USB 2.0 and automatically adapts between Low Speed, Full Speed and High Speed operation, up to 480Mbps. It is driver-free, making it straightforward to use across compatible systems without extra software setup.

Designed for demanding environments, it is suited to high-voltage and high-interference applications such as power systems, inverters and motor drives, as well as noise-sensitive setups like high-precision USB data acquisition and HIFI audio systems. The isolated output power is 1.5W; if connected devices require a working current greater than 300mA, an additional external power supply is recommended.

Features:

• Electrical protection: Uses advanced magnetic isolation technology to create a complete electrical barrier.
• Ground loop isolation: Isolates ground loops between USB devices.
• Surge protection support: Helps safeguard against damage from ground loop voltage, surges, induced lightning strikes, static electricity (ESD), and hot-swapping incidents.
• USB 2.0 compatibility: Supports driver-free operation.
• Multi-rate operation: Automatically adapts to Low Speed (1.5Mbps), Full Speed (12Mbps), and High Speed (480Mbps) communication rates.
• Industrial reliability: Operates in extreme conditions from -40°C to 85°C.
• Plug-and-play simplicity: No external power supply is required for most applications.
• Typical applications: Protection in high-voltage, high-interference settings such as power systems, inverters and motor drives.
• Typical applications: Noise reduction in sensitive areas such as high-precision USB data acquisition and HIFI audio systems.
• Typical applications: Safeguarding USB interfaces on development boards and computer motherboards.
