Acromag USB isolator

Acromag’s compact, industrial-grade isolator provides a high-voltage isolation barrier between a computer and a connected USB device. The isolator protects equipment from electrical surges and transient voltage spikes as well as eliminating ground loop currents flowing between the PC and peripherals, which can damage instruments and cause inaccurate measurements. Additionally, isolation minimises conducted noise from static discharge, magnetic fields and radiofrequency interference.

The isolator inserts inline with the USB connection and operates transparently with no special software drivers 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.

Electrical isolation is provided up to 1500 VAC or 2100 VDC, and surge/transient suppression up to 8 kV on all ports.

A green LED indicates that power is being received and blinks if the connected device draws too much current. The USB isolator has an internal jumper, which allows users to switch from full-speed (12 Mbps) to low-speed (1.5 Mbps) communication. The reset button offers a simple way to reinitialise a connected device without breaking the cable connection. This USB isolator has high-retention USB sockets that keep cables securely attached under shock and vibration.
