We are offering es-25 energy savers-esei-pd002 for street lighting load application, the es-25 energy saver is a highly advanced and sophisticated coil based power voltage optimizer that is installed at incoming electricity supply. It uses a tried and tested technology known as voltage or power optimization to control the voltage and suppressing the load harmonics on lighting and mixed load. This lowers the amount of kwh consumed, which is what electricity bills are calculated on and thus saves electrical energy.
working principle
es~25 is a high efficiency device, which optimizes the voltage (static or dynamic) as the energy consumed increases approximately square of input voltage thereby the output energy would reach to an optimum level, beyond which the energy consumed will be wasted.
the diagram shows energy saving with high efficiency coil system. The main winding a and secondary winding b which is the inverse, phase energy saving winding. When the supply current passes through winding a, magnetic restriction occurs in winding b as b is connected in series to load, the energy induced due to magnetic restriction from the inverse phase current in winding b is expressed as voltage optimization in the load to reduce the energy to the extent of 20 - 25%.
benefits through es 25
- guaranteed savings up to 25% in lighting and 15% in mixed load
- centralized installation without de-lamping or re-laming
- extends the life of discharge lamps and reduces replacement of chokes
- guards the circuit from high voltage spikes and surges
- marginal improvement in power factor
- reduction in carbon emission
- maintenance free with over 20 years life span
- payback period as low as one year.
