Construction

The use of SMT technology and a special plastic housing provide flexibility in controlling the air flap and protection from damage caused by accidents, careless handling, dust and dirt. The built-in varistor prevents damage during power surges. A fuse inside the Brahma MPI 37201260 control unit protects the control relay from short circuits at the outputs (gas valves, motor, transformer, lock signal). It is also recommended to use an external fuse up to 6.3 A for additional protection.
