USB isolator – Isolated USB port

USB isolator – Isolated USB port

Are you asking yourself, why should I use an USB isolator? The answer is simple, to avoid trouble and save money.

We all know that many devices these days can be plugged through USB cable to a single computer. Therefore, computer and peripheral devices (USB device etc.) share the same ground line. That usually doesn’t represent any risk. But what if devices are working in an unfriendly environment or are plugged into high voltage? People always tend to protect computers from lightning and power disturbances. But are we aware that plugged USB devices can also cause damage to a computer?

However, there is a solution in a small hardware device, which isolates data and power supply pins from USB peripheral device. I am talking about a USB isolator. This tiny but efficient interface separates electrical connection between computer and external USB devices.

One of the most reasonable use of USB isolator, is using it with devices such as USB Oscilloscope or Logical Analyzer. Such USB devices are powered by 5V when plugged to computer. But there can be many ranges of voltages and different grounds on device under test. When we are performing measurements and we are not paying enough attention to grounds, we could get invalid and incorrect results. In some cases it can lead in faulty USB port. Even worse, it can end with destroyed motherboard.

PoUSBiso can easily fix several problems, such as ground loops, harmful noise, surges and spikes.

It is a small plug and play solution. No drivers are needed. It provides 1kV isolation of USB full speed (12MHz) device from computer. There is 400mA isolated current available on secondary side. One of additional features of PoUSBiso is external 5V power jack on secondary side if higher current is needed.
