1. This charger is mainly to solve the problem of charging the 12V sub-battery of the RV (all 12V batteries are common). The main problems are solved as follows: 1. When the generator voltage is low, the secondary battery cannot be filled. 2. When the generator voltage is too high or the secondary battery voltage is too low, the charging current will be very large at this time, the generator is prone to heat or even burned, and there is a great hidden danger to the entire charging system. This problem can be solved perfectly with this charger.
2. The external ACC delay starts the control line port, and connects the positive line of the port to the ACC end (the negative line does not need to be connected), which can realize the 60S automatic start charging after the car starts to prevent the damage of the generator caused by the large current during ignition. The charger is automatically turned off after the vehicle is turned off, and the main battery is protected from power consumption.
3. Input undervoltage protection, voltage adjustable, this function can effectively protect the main battery from over-discharge after adjusting the under-voltage value. When the vehicle is idling, it will automatically reduce the output current, protect the generator, and automatically stop charging after the vehicle is turned off.
4. No double battery isolators are needed, and the isolation and charging do not affect each other. After the car is turned off, the charger has a servo current of less than 5 mA.
5. The output constant voltage constant current is continuously adjustable, and the maximum charging current can reach 50A.
6. With charging voltage and charging current display, the voltage and current are clear at a glance.
7. There is a charging indicator light, after setting the full turn-on lamp current, the red light is on during charging, and the blue light is turned on after being fully charged.
8. There is a full charge shutdown function. When this function is turned on, the output will be automatically turned off when the battery is fully charged to prevent the battery from being overcharged and damaged.
9. There is battery power supply supplement function. After turning on this function, adjust the voltage. When the battery is fully charged and turned off, the battery voltage will automatically turn on when it drops to the set voltage after use, preventing the battery from being too low and replenishing the battery in time. .
10. With intelligent temperature control fan cooling, with over temperature protection (with indicator light).
