Feature: 1. Working Principle: When the power saver box works under rated load, it uses the capacitor system to release its stored power more smoothly to the normal state without spikes. 2. Power Saving Effect: The function of the power saver box is to stabilize the voltage, balance the current and surge protection to achieve the power saving effect. It can also improve the power used by electrical appliances and avoid invalid power waste, thus extending the service life of electrical products. 3. No Additional Consumption: The energy saver itself consumes almost no energy, so you can use it to save the electricity consumed by appliances such as refrigerators, air conditioners, TVs, etc. Even if it runs 24/7/365, it will not increase the burden of electricity bills. 4. Simple Operation: Simply plug the power factor energy saver into an electrical outlet, the green indicator light will come on, then start working by keeping the device connected, it will reduce your power consumption and save power effectively, up to 20% to 35% for heavy loads. 5. Safe and Reliable: Energy saver shell is made of fireproof and explosion proof material, with internal leakage protection measures, safe and reliable, suitable for houses, apartments, condominiums, store lots, restaurants, hotels, offices, small factories.
