and high quality. Invert DC 12V to AC 220V ( Maximum: 230V ). Reliable variety of household AC products, such as portable stereos, laptop computers, camcorders and mobile phones etc. Protect the electrical and automotive circuits in use. Intelligent cooling fan system, CPU microprocessor to realize multiple protection . It automatically shut down in the event of short-circuits, low .battery power, DC input voltage overload, DC output voltage overload and excessive temperature. LED display shows DC and AC voltage . Adopting aluminum alloy case, antioxidant, sturdy and . Pure sine wave inverter, 110V / 220V for city power supply and power quality, so it has. One inverter can be used for multiple purposes: home, solar, car, outdoor Input voltage:DC 12V Output voltage: AC 220V Output frequency: 50 + / - 2Hz Fuse: 10A / 15A / 20A / 30A / 40A / 70A Low battery alarm ( nominal ): 9.5 - 11.0V Low battery shutdown point ( nominal ): 9.0 - 10.5V High battery shutdown point ( nominal ): 14.5 - 15.5V Unload current: Less than 0.3A Conversion efficiency: 90 percent Continuous output power: 900W power: 2000W Note: 1.If the cooler (fan) not work, it is normal, the temperture reach a certain temperture, or too hot, then the cooler work. 2. Please the Rated Power is higher than the electric appliance you wanna apply to. 3. And if you wanna run several appliance at the same time, you should refer to the total Watt. 4. If you wanna run a inductive load for a long time, it`s suggested to buy a pure sine wave inverter.
