Features:- Save electric power resources up to 35%.- Improve the power factor- Stabilizing electrical current- Surge protection- Reduce current wave form distortion- Protect the appliances and prolong their life, especially for air conditioner, washing machine, freezer, TV, computer...- Most effective with inductive receivers (e.g. Motors, trans-formers, fluorescent lighting...)- Protect the environment- Easy to use, maintenance free- Fully compliant with safety standards- Metal cover. How It Works:- POWER SAVER use a state of the art electrical technology to actively monitor and improve the power factor of your household / office appliances. In addition, the intelligent technology optimizes the voltage and current demands thus reducing the active power / Kwh demands and achieves max up to 35% savings on your electricity bill, if also acts as a voltage stabilizer by storing energy for up to 10 seconds and therefore supplies the load with constant voltage during momentary power surges. This in turn results to longer lifespan of the electrical appliances Installation Procedure:- Plug this device into a wall socket, not an extension cord or multiple socket and switch on the unit.- When you see 1 red-LED light turn on,the unit has started saving electricity.- Install one power saver to each phase.Color: WhiteProduct Size (L x W x H): 142.4 x 82.3 x 38.3mmPackage Weight : 302g Package Include:1 x Power Saver1 x English Manual
