This telemetry sensor detect amperage pulsing thru your aircraft and transmits the data back via the FrSky Smart Port telemetry system. This sensor requires an X series receiver. Will not work with V8 or D series.
The FrSky Ampere Sensor (SP-40A) can measure Current (A) and battery voltage(V) when connected between a Battery and ESC. This sensor requires a Smart Port enabled reciever such as the X series FrSky receivers like the X8R.
Measurement range 0~40A
Maximum safe current 40A
Maximum battery voltage 6S
Sensor current consumption 25mA@5V
