USB-to-USB Isolator protects your PC or Laptop while connecting USB peripherals wired to high voltages

USB-to-USB Isolator protects your PC or Laptop while connecting USB peripherals wired to high voltages. This small, industrial- grade isolator is very easy for use and provides a high-voltage barrier for protection against surges, noise and ground loop errors. It is suitable for use in sensitive applications like the automotive measurements.

This compact, USB 2.0 compliant port isolator provides a high-voltage isolation barrier between the computer and the connected USB device. The isolation protects the equipment from electrical over-voltages and transient voltage spikes. It also eliminates ground loop currents flowing between the PC and USB device which can cause damage and inaccurate measurements. Additionally, isolation minimizes conducted noise from static discharge, magnetic fields and radio frequency interference.

Ditex USB isolator is USB bus powered and can provide 5V/400mA for supplying your USB device with built-in isolated DC-DC. This is possible when the isolator is connected to a high power USB host port.
