The Central Braking Module is a cabinet unit with integrated braking chopper. Using state-of-the-art MOSFET/IGBT semiconductors, the power unit controls when the braking resistor is switched-in.

Central Braking Modules are designed as a 400 mm wide cabinet module. Its connection to the DC link is protected by fuses.

Central Braking Modules require braking resistors that must be externally mounted and which can be ordered separately. The cables to the resistors can be connected to lugs which are specially prepared for plant application and which are located in the connection area of the cabinet.

The power units have diagnostics LEDs for the display of faults and also a control output for the communication of faults. The Central Braking Module can be disabled externally via a control input.

The arrangement in the DC link system is subject to specific configuring rules.
