USB isolator – Isolated USB port
Are you asking yourself, why should I use a USB isolator? The answer is simple, to avoid trouble and save money.
We all know that many devices these days can be plugged through a USB cable to a single computer. Therefore, computer and peripheral devices (USB devices etc.) share the same groundline. That usually doesn’t represent any risk. But what if devices are working in an unfriendly environment or have a high voltage supply? People always tend to protect computers from lightning and power disturbances. But are we aware that plugged USB devices can also cause damage on a computer’s USB port?
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 connections between computers and external USB devices.

Use of USB isolator
One of the most reasonable uses 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 a 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. You don’t need to install any driver. It provides 1kV isolation of USB full-speed (12MHz) device from computer. There is 400mA current available on the secondary side. One of the additional features of PoUSBiso is an external 5V power jack on the secondary side if we need a higher current.
