Function: 1. MAIN APPLICATION: The function of the energy saving module is voltage stabilization, current balancing and surge protection to avoid inefficient energy waste. 2. GREEN INDICATOR: Simply plug the energy saving do of the electrical outlet, the green indicator light will light up, and then start working without connecting the device. 3. SAFETY AND RELIABILITY: When the energy saving module operates pod rated load, it is safer to use a capacitor system to release the stored energy do of the normal state more smoothly. 4. ENERGY SAVING: This energy saving reduces energy consumption and effectively saves energy, do 20%-35% for heavy loads. 5. .
