The use of special manufacturing technology and the introduction of SMT technology have made it possible to obtain an extremely flexible device that can control the air flap. The plastic housing protects the control panel from any damage resulting from accidents, careless handling, dust and dirt ingress. The varistor protects the control panel from power surges in the network. A built-in fuse protects the internal control relays in the event of a short circuit at the outputs (gas valves, motor, transformer and lock signal). Since this is not an emergency fuse available, the Brahma MPI23 37201350 control unit must be protected by an external high-speed fuse suitable for connected loads and not exceeding 6.3A.
