Product Specification
- Charger integrates active power factor correction(PFC), can achieve zero pollution of power grid and avoid the impact of large current grid；
- Wide range of AC input voltage, strong adaptability；
- The module has the perfect protection function such as input over-voltage, lack of input, output over current, over voltage output, output short circuit, output isolation protection, module overheating and so on；
- The full-bridge phase-shifted soft switch PWM the latest mixed-mode control, to overcome the traditional phase-shifted full-bridge circuit circulation loss, working conditions of diode side faults, secondary-side diodes to achieve soft recovery, the module can achieve high efficiency over a wide input voltage range and the maximum load range.
- Efficiency close to 97%, the electromagnetic interference is greatly reduced, and the volume weight is greatly reduced;
- Improved thermal design, more uniform heat distribution;
- The use of a more complete circuit board dust, moisture-proof treatment;
Product Characteristics
- Single-Chip Microcomputer (SCM) according to the lead-acid batteries tolerance current capacity, life curve, gas analysis point and other information to complete the full charge of the whole process;
- With the environmental temperature compensation function, to ensure that the temperature of the weather conditions, can automatically resist over-charge and under-charge;
- With pulse charging function, the battery is filled with the premise of ensuring the best life of the battery；
- After three paint processing and dustproof design, the reliability of the operation is improved;
- With digital display function, can display online charging current, voltage, charging time;
- (smart car battery charger, portable car battery charger)
