The train controller
I will describe to you my design of the railway regulator for TT train models, which has the following features:
Regulation of train speed (PWM), 0-100% with LED bar graph - indications.
Control (LED) lighting (PWM), 0 to 100% (for additional lights in buildings ...).
Remote control for switching tracks to (6 channels).
Classic controls, industrial switches and buttons.
The controller also has a separate switching output (16V) for „public“ lighting.
Regulating the speed of the train is a classic pulse-width modulation(PWM), as well as supplemental lighting control. The regulator has the opportunity slow response, switch on / off which simulates the real situation of starting and stopping trains. In case of a short circuit on the track's end provided a transistor current resettable fuse and a thermal sensor.
The regulator are following parts:
- Main PCB - PWM control train
- PCB secondary PWM for lighting and other outputs for each power supply.
- PCB to indicate speed train with LED bar graph
- Several power modules for general lighting is current limited
- Wireless relay module
- Classic EI transformer 230VAC / 2x20VAC (100W)
Soon there are more features and process constructions...
