The EPS Power Saver uses a combination of filtration and correction techniques to improve the efficiency of various appliances and circuits. In addition, the intelligent technology optimises the voltage and current demands thus reducing the active power / KWH demands and achieves around 10% to 20% savings on your electricity bill. It also acts as a voltage stabilizer by storing energy for up to 10 seconds and therefore supplies load with proper voltage during momentary power surges.
