Optimizers work by improving your systems power factor. Electrical Optimizers are useful for household appliances like washing machines, refrigerators, and dishwashers, tv as well as heavy duty equipment like conveyor belts, escalator systems and rooftop A/C units. An optimizer uses apparatus that determines the specific amount of power needed, thus eliminating the wastage of power that is consumed when the equipment uses surge power to start functioning. Also, with better stabilization of voltage, it reduces the chances of potential damage to the motors due to the accidental power surge.
All this results in better performance with lesser maintenance and services, ultimately leading to lowered energy consumption and costs.
