Usage Tips:he voltage protector operating instructionthis is a voltage protector,good for an automatic protection of the home appliances in case under-voltage ultra-voltage and electricity stoppage for instanceit may be always harmful to the normal operation cut their service lifeor even burn down the compressor motors for air -conditioner ,refrigerator 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,which can immediately disconnect the load supply and provide the compressorwith a time - restart power reconnection with a perfect result of protection for the compressor Appliations 1 insert the protector plug into the supply sockect ,those of the air -conditioner ,refrigerator ,freezing cabinet into the output socket of the protector 2 when in stall this protector one may directly hang it up on the wall by the hanging hole it back case 3 Obiects of Applicability air -conditioner,refrigerator ,freezing cabinet Note 1 Do not install this protector in the positions afflicted with high temperature and moisture 2 using it in a dirty ambience and a severe oxidation with the plug may lead the protector to an early damage Specifications: 1.220V, 50HZ, 110V, 60HZ 2. voltage range:90+/-3%~130+/-3%(60HZ); 180+/-3%~250+/-3%(60HZ); 3. current range: 16A(Max) 4.
