Carrera Control Unit For the Carrera Digital 132 or Digital 124 racetrack. The control unit has an additional Mosfett (tuned for 8 amps). Please also note my other offers in my shop. A MOSFET works as Voltage controlled resistor in which a voltage is applied Gate the current flow between Source and Drain controls. Is a certain voltage (Threshold voltage) is exceeded, a conductive channel is formed that allows current to flow. If the voltage is lower, the resistance is very high and no current flows. Not suitable for children under 3 years.
