  • The A3100 includes two fully featured independent controllers and two independent power circuits within a single 6U 19 inch enclosure, all available as removable cards (single channel option available).

    The A3100 builds on previous experience and technologies from BRUSH, incorporating features such as integrated power system stabilizer, automatic synchronizer, R10 ground (earth) fault receiver, Ethernet and USB connectivity integrated into a single standard 19 inch rack package. With most connectors completely compatible with earlier Brush controllers the A3100 is an easy replacement of previous Brush AVRs such as the MAVR, MicroAVR, A30 and even the A32.

    BRUSH can provide engineering expertise to help replace other OEM Brushless AVRs up to 20A rating with the A3100. Click to contact the Sales team for further advice.
