PWM – Pulse-width Modulated Signals (UniTrain)

Many actuator systems in motor vehicles require variable power levels for the devices being controlled. Actuators which need to assume intermediate values between the ON and OFF limits are controlled by means of pulse-width modulated signals. With our training system trainees document their measurement results, signals and fault protocols and analyse, evaluate and present their findings. This way they are able to isolate faults and propose suitable strategies for fault rectification.
