Worksite traffic lights - LED technology – self-contained

Simulator of worksite traffic lights powered with solar energy. Two artificial and variable light sources simulate sunlight and enable the batteries to be recharged. Fully self-contained, operation of the FEU-LED is managed with a Schneider® PLC.One solution for manually recharging the batteries is included in the electrical unit.

Educational objectives
• Study and putting into service of solar energy worksite traffic lights.
• Reminder on the different solar panel technologies.
• Wiring of the components of a photovoltaic installation at an isolated site.
• Reading the different electrical values of the production system of solar energy.
• Calculation of the efficiency of the installation.
• Programming a controller (PLC).
