　　品牌WTD型号120W输入电压范围220输出波形正弦波输出功率120冷却方式自然冷式冷却介质干式 DC TO AC power supply inverter for carDirection for use■ Instruction It can change the DC 12V into AC 220V（120V）output. And it can be widely used in all kinds of electrical apparatus, which voltage rating are AC 220V（120V）and frequency are equal to 50Hz（60Hz）., such as mobile telephone, portable compute, electric light, digital camera, vidicon,TV,electric tool, CD player, DVD, fanner and so on. It is the best choice for your field survey, driving out outdoor office, or meeting an urgent need when power failure.■ Specialities of the productIt can be made from advanced PWM CMOS chip, and can work in the state of ultrasonic sound, which can both in a great extent minish the bulk and weight and make the circuit work without noise. So it is small, light, quiet and convenient. It can protect the electric circuit in a great degree. For example, it can automatically switch off when the voltage of the car battery is low of 10V, so that your car can normally start. And the output of the product is a universal socket, which can be used in many countries. And the newly-added USB output socket can be directly used to charge for MP3 and mobile phone.■ Means of usage ☆ put the change-over switch to “OFF” or “O”.☆ Connect the electric cord with the product to the correct terminal, for Example, the red wire goes to the positive terminal. Except for the inverter Which power is below 120W, because it only has the socket for lighting Cigarette.☆ The socket for lighting cigarette can just provide the power below you must connect the alligator clips with the product to the poles of battery when the output power is above the 130W.☆ Be sure of the power of your electric tool is below power rating of the product .☆ The green light will be on if the change-over switch is in the state of “ON” or “∣”. The product is in the state of protecting if the red light is on, please turn it off and check it is overloaded or short cut, and the voltage of battery is abnormal or not.■ Technical parametersModel SVP-150120 SVP-150220 Power rating 120VA 120VA Max. power 150VA 150VA Max. efficiency ﹥88% ﹥88% Input voltage 12V 12V Lower pressure stop 10V±0.5V 10V±0.5V Over voltage stop 15V±0.5V 15V±0.5V Output voltage 120V±10% 220V±10% Output frequency 60Hz±3Hz 50Hz±3Hz Output wave corrected sine waveVolume 100﹡89﹡47 100﹡89﹡47 Weight 0.4 Kg 0.4 Kg The product is guaranteed for one year, except for the failure by your fault and teardown by yourself ,and please send this sheet with the product to our company when you need repair.
