The NF-SD2 controller serves to limit the speed of movement of servo at response to a change of position.
Retarder of servo movement NF – SD2
The NF-SD2 module (Night Fly – Slow Down) serves to limit the speed of movement of servo at response to a change of deviation. The unit is designed for aeromodellers for slow pushing out of landing gear and wing flaps. In ship-modelling and models of military or construction machines, the unit can be used for slow, fluent positioning of gibs, special bodies, opening of bars and tops, slow starts and slowing down. With that kind of technique, you will appreciate long running times – they can be set in the range between 0.7 to 14.7 for run between the end positions.
The module reads information about the desired deviation of servo from the receiver and sends it to output. In the stable state, the values on input and output are equal. When a fast change on input occurs, the output starts changing slowly so that the set maximum speed is not exceeded. The maximum speed can be used won a trimmer with a small screwdriver. With switch-controlled channels it makes possible a fluent, linear change of deviation on a model.
