The Altitude Motor Switch (AMS) is a versatile device suitable for several competition categories where the altitude or motor run time shall be limited. It can be used also as a standalone telemetric variometer. The sensor is usually connected between the receiver throttle channel and the appropriate signal input of the electronic speed controller.
|Dimensions [mm]||27 x 11 x 5|
|Telemetry||Duplex EX, Multiplex MSB, Graupner Hott, Futaba S.Bus2|
|Operational temperature [°C]||-20 – 85|
|Supply Voltage [V]||3.5 – 12|
The AMS contains a sensitive barometric altimeter/variometer which uses the latest MEMS technology to achieve a high level of accuracy, while preserving miniature dimensions. The sensor is able to detect tiny changes in atmospheric pressure to indicate the change of altitude with resolution 0.1m. Using the integrated high power cables you can directly power the receiver and servos through the AMS from a BEC circuit of the speed controller.
