Saving energy in lighting systems

up to 30 % potential savings and stable mains voltage

Save energy during the night shift – Voltage optimization for street lighting with energy2save

Rising energy costs make optimization of power consumption one of the most important tasks for municipalities and enterprises. energy2save from Ruhstrat is able to significantly reduce power consumption for long-term reduction of operating costs.

These savings potentials can be achieved with energy2save from Ruhstrat. The system uses an electronic transformer to lower the mains voltage, stabilize it at the desired level and therefore reduce the power consumption of lighting systems by up to 30 %. The lights themselves respond to this change with slightly reduced luminosity which is hardly noticeable by the human eye during the evening and night. A further advantage is the longer life cycle, because the system keeps the load voltage at a constant level by compensating for fluctuations that occur in the mains network.

This compact energy savings system is designed for easy integration in existing street lighting systems without expensive modifications. No changes must be made to the individual streetlights. The supply voltage can be configured as needed and is linear throughout the entire range – without disruptive voltage bounces. Consequently, this technology makes it possible to provide lighting systems with a temporal brightness curve.

The system is ideal for mercury vapour high-pressure lamps, sodium vapour highpressure lamps, metal halogen vapour lamps or fluorescent tubes. energy2save is so flexible that even streets with different lamp types can be controlled in mixed operation with no difficulty.
