Black Box SP387A USB Isolator
Overview
The Black Box SP387A is a USB 1.1 compliant isolator designed to protect sensitive equipment from damaging electrical surges and noise. It provides up to 4 kV of isolation, making it suitable for environments with high electrical interference, such as hospitals and medical facilities. This device is critical for safeguarding USB peripherals and the host system from transient voltage spikes and ground loop currents, ensuring operational stability and data integrity.
Compatibility
This isolator is compatible with any USB 1.1 device. It functions as a transparent pass-through, requiring no software drivers. Deploy it between your host computer or USB hub and any USB 1.1 peripheral, including keyboards, mice, printers, and certain medical sensors or diagnostic equipment that utilize USB 1.1 communication.
Installation Notes
Installation is plug-and-play. Connect the isolator between the USB host and the peripheral device. Ensure both the host and peripheral are powered off before connecting the isolator to prevent potential damage. The SP387A is designed for indoor use and should be protected from moisture and extreme temperatures.
