Available as single box + USB cable replacement

Usage & Benefits

The USB isolators effect a potential decoupling of all USB connections and separate the 'normal' PC system from the critical application.

Protection & security

They are the professional tools to avoid and fight ground loops and equalizing currents and to protect against overvoltage.

Certified quality

High isolating voltage and certification according to IEC60601-1 recommend the isolators also in sensitive applications.

Advanced Safety


IFTOOLS continues to take the USB isolation to the next safety level.

The ISOUSB-PLUS isolator series provides you with:

  • TÜV certification to the highest safety standard IEC 60601-1 Rev 3.2
  • Isolation 7500 Vdc 1 second, 5000 Vrms 1 minute
  • Robust shielded metal housing
  • High retention force connectors (box)

Good to know

Certified against EN60601-1 Rev. 3.2 means the highest quality standards and reliability through selected components and best possible design. You should not expect less!

Medial & Fitness

Whenever a human is connected to a PC for medical or monitoring reasons you must take precautions that the person must never suffer harm due to possible or accidental defects. Safety first always applies!

Industry & sensitive applications

To protect control systems and PCs against power surge, voltage burst and ground loops caused by connected USB devices working in harsh environments.

Makers & Developers

For all people who develop, test or simply work with USB devices and want to avoid to damage their USB hub or, even worse, their PC just by accident.

Audio & Sound studios

Fighting buzzing and other unwanted noises coupled by connected Audio/Midi devices with own power supply forming a ground loop. The isolator Full Speed 12Mbps is sufficient for sample rates up to 96kHz/24bit.

And just in case...

Do not take any risk when you need to connect a used and possibly defective USB device with your irreplaceable PC. Especially in the service area. Always play it safe with the ISOUSB-PLUS isolator.
