Major functions: remove disorderly wave, stabilize current, and provide stable working voltage for the power consuming units in the car. Four advantages: 1.Supreme voltage stabilizing design. It further stabilizes the function of the ecu and makes the matching calculation of the gas input and the fuel injection more precise, thus sufficiently burning the fuel oil, and at the same time reducing the emission of the tail gas, so that it truly achieves the effect of oil-saving and environmental protection. 2.Double complementary design. It effects real-time monitor of the working status of the storage battery, supplements different working currents, and reduces the load of the storage battery, thus extending the life span of the storage battery. 3.Anti-interference design. It can filter the various disorderly electric waves from inside or outside the car, and greatly raise the audio-visual effects, making the sound quality more perfect. 4.Big capacity design. It makes the headlight brighter when used together with the storage battery. Technical parameters: Input voltage: 10í½16v output voltage: 14í0.2 v Working current: 60 a working power: 800w Working temperature: í¬20íí½105í Installation: firstly fix the rectifier in a position with good ventilation, connect the red end of the rectifier with the positive pole of the storage battery and make it firm, and then connect the black end of the rectifier with the negative pole of the storage battery and make it firm. It is ready to work without testing. Note: do not start the vehicle while installing. Please shut up the headlight, the audio and other appliances Oem is warmly welcomed.
