USB Isolators

Acromag USB Isolators are compact with industrial grade strength. They provide a high-voltage isolation barrier between a computer and a connected USB device.

USB Isolators

Firstly, the isolation protects equipment from electrical surges and transient voltage spikes.

Secondly, it also eliminates ground loops currents flowing between the PC and peripherals. Which can cause damage and inaccurate measurements.

Thirdly, isolation minimises conducted noise from static discharge, magnetic fields, and radio frequency interference.

Acromag’s USB isolator is very easy to use. The isolator inserts in-line with the USB connection and operates transparently. No special software drivers are required. The unit receives power from the PC’s USB port and isolates that power to the connected device. High noise immunity and low radiated emissions ensure reliable data transfer in sensitive applications.
