SKU: EZSync3103 Category:


EZSync USB Isolator protects PC or Laptop while connecting USB peripherals which is wired to high voltage. This small, industrial-grade isolator is very easy to use and provides a high-voltage barrier protection against surges, noise and ground loop errors. It is suitable for use in sensitive applications like automotive measurements. USB isolator provides a high – voltage isolation barrier between computer and it?s connected USB device. The isolation protects equipment from electrical over-voltages and transient voltage spikes, by eliminating 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. USB isolator is USB bus powered and can provide 5V 180mA to your USB device with built-in isolated DC-DC converter.
