Energie Production
A pick-up coil is installed in the WOLTRONIC SNM, which uses electromagnetic induction to generate electricity from the contact wire. This technology enables energy to be generated from the overhead line and ensures safe galvanic isolation between the contact wire and the module.
The WOLTRONIC SNM uses solar energy as a second power source. Photovoltaic cells are integrated on top of the housing, which supply electricity from renewable energy from the sun.
Energie Storage
In order to ensure the power supply of the WOLTRONIC SNM even on cloudy days and low train frequency, there are two energy storage devices in the module in the form of high-performance capacitors and lithium-iron-hydride batteries.
Both technologies guarantee to supply enough energy even at extreme temperatures.
Power Management
The power management knows the status of all available power sources, selects them depending on the conditions and thus ensures uninterrupted operation.
