Product Features:

1. By using heat dissipation with an airfoil, the heat dissipation effect is significantly improved and the output power is greater (the power can reach around 120W when 28V input is added with a fan).

2. Newly designed, with a conversion efficiency of up to 90.5% (see the efficiency conversion curve in the data manual below for details).

3. Large size iron silicon aluminum magnetic ring, made of two 1.2 pure copper enameled wires, with low heat generation and high efficiency.

4. The brand 3296W multi turn potentiometer has high adjustment accuracy and small drift.

5. Adopting independent reference IC, 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. With constant current function, it can be used for high-power LED lights, charging batteries, and so on.

8. With overtemperature protection, it can effectively protect the power tube from overheating. The protection adopts the reduced power protected mode, which is not directly closed. During battery charging or LED power supply, the output power will slowly decrease when overtemperature occurs, and will automatically recover when the temperature drops.

9. The output is equipped with short-circuit protection, eliminating the drawback of the boost module without short-circuit protection.

10. Dual color indicator light, with a current of approximately 0.2 times the crossflow value, indicating a 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. It is very suitable for charging 12.6V 14.4V lithium batteries in cars, and can input 10-30V and output stably at 12.6V, 14.4V, 14.6V, 16.8V, and so on

The default output voltage for shipment is around 12V, the current is around 4A, and the undervoltage protection is around 10V. If you need to adjust to other voltages at the factory, please place an order and contact customer service.
