Energy saverusea state of the art electrical technology to actively monitor and improve the power factor of your household/office appliances. In additional,the intelligent technology optimizes the voltage and current demands thus reducing the active power/kwh demands and achieves up to 30% saving 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 lifespan of the electrical appliances. For it to work optimally, it should be installed as close as possible to the point of the entry of your electricity supply so as to detect all loads before the meter and adjust the power factor accordingly. Product features: Reduce your electricity bill up tp 30% Easy to use,No wiring required Improve elctrical efficiency and power factor Maintanance free Reduce electrical overheating Rapid return on investment Reduce power loss Fully complianct with safty standards Stablize the supply voltage Environmentally Friendly Technical Data: Rated voltage:90V 250V Rated Frequency:50Hz 60Hz Single phase model Useful load:19000W
