In an analogue environment, the electronics is responsible for a constant brightness even at low voltages.
In an analogue system, the controller is responsible for constant brightness. Once adjusted, its impact during operation can no longer be changed. The speed of the model is controlled independently of this electronics via a joystick box outside the model.
In a digital system, a driving decoder controls the driving speed as well as other additional functions, like switching sth. on or off (eg direction indicators), dimming sth. (eg interior lighting) or volume controlling (moving vehicle).
To optimize the power supply and to ensure the most quiet and smooth ride, Digi-Trolley™ is supplied with an ‘anti flicker capacitor’ by default. If this component doesn’t do a job good enough, you may add additional capacitors yourself (depending on the available space in the model). Be aware, however: If the overall capacity of these parts is too high, other components may be damaged.
Initially, Digi-Trolley™ only supports DCC.
