80W automatic voltage regulation power module DC10-35 to 1-35V constant current and constant voltage vehicle battery charging
1. By using wing shaped heat dissipation, the heat dissipation effect is significantly improved, and the output power is greater (when 28V input is added with a fan, the power can reach around 120W).
2. New design with a conversion efficiency of up to 90.5% (details can be found in the efficiency conversion curve in the data manual below).
3. Large size iron silicon aluminum magnetic ring, using 2 1.2-purity copper enameled wires in parallel, with low heat generation and high efficiency.
4. Brand 3296W multi turn potentiometer with high adjustment accuracy and small drift.
5. Using independent reference ICs, multiple alloy sampling resistors, constant current stability, and small temperature drift.
6. The undervoltage protection is adjustable, which can effectively protect various batteries and can also be used for solar cells.
7. Equipped with constant current function, it can be used for high-power LED lights, charging batteries, and so on.
8. Equipped with over temperature protection, it can effectively protect the power transistor from overheating. The protection adopts a power reduction protection mode, which is not directly turned off. When charging the battery or supplying LED power, the output power will gradually decrease when the temperature drops, and it will automatically recover when the temperature drops.
9. The output is equipped with short-circuit protection, eliminating the drawback of the boost module not having short-circuit protection.
10. Dual color indicator light, with a current of approximately 0.2 times the crosscurrent value, indicating clear charging status at a glance.
11. The addition of MLCC ceramic capacitors significantly reduces the output ripple, which is about 200 millivolts at 12V 2A.
12. Very suitable for charging 12.6V and 14.4V lithium batteries in cars, it can input 10-30V and output stably at 12.6V, 14.4V, 14.6V, 16.8V, and so on
