Lee Sheng-electronics factory Teaches you regular charger judge good or bad performance: 1: 30 yuan lower than the market little actual power charger, parametric design imprecise, please pay attention to distinguish 2: charger regulator circuit failure will cause the output voltage 75 --- 130V, rechargeable battery light does not turn hot. Lee Sheng-electronics factory Teaches you electric car charger Troubleshooting maintenance solutions for common problems: no DC voltage output, but the insurance slightest intact - 1, should first determine what the charger becomes king in control chip UC3842 whether for state or have been damage. To determine the specific method is: powering UC3842 measured 7 feet on the ground voltage, charger motorcycle manufacturers, if 7 feet and 8 feet voltage normal voltage + 5∨, Wenzhou motorcycle charger, 1,2,4,6 foot It will have a different voltage, then oscillation circuit is enabled, motorcycle Which charger, UC3842 normal. If the 7-pin voltage is low, motorcycle chargers offer, remaining pins no voltage, then the UC3842 is damaged; 2, if none of this breakdown a few feet, but the charger is still does not start, but also that UC3842 has been damaged, should be directly replaced. Motorcycle charger Which is good, Wenzhou motorcycle charger, Lee Sheng Electronics Factory factory direct supply by Lee Sheng Yongkang Electronics Factory.
