1500 Watt Continual 3000 Watt Surge Pure Sine Wave Power Inverter Converter Transformer 12 V Dc Input / 220 V-240 V Ac Output 60 Hz Frequency Power Tools Simply connect Power Inverter with a Battery,for example as in a Car, Motorcycle, Camper or Boatand use 230v 60hz electrical appliances! Ideally suitable for Journeys, Camping, Tents, Boat Trip,Working on the way and everywhere, where is no electricity! Input Low Voltage Protection, Input Reverse Polarity , circuit protection, Overload protection, Short circuit protection!Built-in fuse & cooling fan,Resume after protections triggered! High tech achieved: Input & Output Isolation avoid electric shock ! Built-in fuse & cooling fan. Resum working after protections! The Power Output is very constant.When using Strong Machines the IC Program recoginizes this and provides at the beginning a Higher Power which adapded later!
