The voltage protector is good for an automatic protection of the home appliances in case of under-voltage, ultra-voltage and electricity-stoppage.For instance, it may be always harmful to the normal operation, cut their service life, or even burn (down the compressor motors for air-conditioner refrigerators and freezing cabinets if the supply voltage is too low or too high. Especially,instant power stoppage and restarting supply with the electricity net creates a strong voltage impact which is very hazardous and may damage the compressors. Operation Instruction: 1.Max output current: 15A for buyers choose. The exact specification, pls check the product back printing. 2.Voltage: 220V, 50HZ,or 110V,60HZ for buyers to choose. The exact specification, please check the product back printing. 3.Green LED ‘’TURN ON’’ indicate working on the normal voltage range BETWEEN 165v-250v or so. For USA Buyer, 110V standard, the range is 90v-140v, if less 90v or over 140v, it will be disconnected. For EU/UK buyer, 220V standard, the range is 160v-270v, if less 160v or over 270v, it will be disconnected. 4.Yellow LED‘’TURN ON’’: indicate programme run into delay, delay time: 180 seconds or so. 5.RED LED ‘’TURN ON’’: means OFF, indicate the voltage too high or too low, out of the normal range. 6.Lighting-up of the"High-VP" yellow LED, indicate protecting valid when the voltage is more than highest, the device cut the power. 7.C-start : meaning you can press it to cancel the delay time and go on for protecting.
