Murrelektronik’s active brake rectifiers simplify DC brake connections by combining the contactor and rectifier modules in one compact component, enabling DC brakes to be controlled directly from the control cabinet. The devices, which are UL approved for worldwide use, receive signals from the PLC via a 24-VDC control input. A semiconductor switch then controls the rectified output voltage of the brake. Approved main voltages from 230 VAC to 480 VAC make them suitable for a variety of applications. Also included is an integrated semiconductor switch to eliminate maintenance needs.
