ABM Electronics MBE3-50 Drive Control

ABM Electronics MBE3-50 Drive Control, also cataloged as the MBE350, is a drive controller intended for active magnetic bearing (AMB) systems, providing the electronic interface that powers and stabilizes rotor levitation in specialized machinery. The unit accepts 3-phase AC input at 400–500 VAC (50/60 Hz) with a stated input current of 1 A, supports a DC link from 400 to 800 VDC, and offers an output of 2 A at 50 V to drive the bearing coils, with digital control and built-in protection features to ensure stable operation. This device is described in multiple listings as magnetic bearing electronics and is listed as discontinued by the manufacturer, while several sources note configurations compatible with 380–400 VAC service and frame the MBE3-50 / MBE350 as a compact, stand-alone drive controller for AMB systems.
