Frequently Asked Questions
What is a USB-to-USB isolator and why do I need one?
A USB-to-USB isolator creates electrical separation between connected devices, preventing ground loops and voltage spikes from damaging equipment. This is essential when connecting devices with different ground potentials, integrating legacy systems, or protecting sensitive laboratory instruments from electrical interference.
How does 4-kV isolation protect my equipment?
The 4-kV isolation rating means this isolator can safely block transient voltages and common-mode noise up to 4,000 volts. This protects your USB devices from surge damage, data corruption, and hardware failure caused by ground loop interference and electrical noise in your network.
Is the Black Box SP387A compatible with all USB devices?
Yes, the SP387A works with any standard USB device. The included 3.3 ft cable provides immediate connectivity, and the single-port design integrates seamlessly into existing IT infrastructure without requiring additional configuration or drivers.
What does the 5-year warranty cover?
Black Box's comprehensive 5-year warranty covers defects in materials and workmanship, ensuring your USB isolator investment is protected against hardware failure and manufacturing issues throughout the warranty period.
