    • The airfoil has a significant heat dissipation effect and a larger output power;

    • New design, conversion efficiency up to 90.5% (for details, see the data sheet efficiency conversion curve below);

    • Independent reference IC, multiple alloy sampling resistors, constant current and stable temperature drift;

    • The under voltage protection is adjustable, which can effectively protect various batteries and can also be used for solar cells;

    • With constant current function, it can be used for high-power LED lights, charging batteries, etc.

    • With over-temperature protection, it can effectively protect the power tube from overheating. The protection adopts the power-reduction protection mode. It is not directly closed. In the battery charging or LED power supply, when the over-temperature will slowly reduce the output power, when the temperature drops. , will automatically recover.

    • The output has short circuit protection, which eliminates the disadvantages of the boost module without short circuit protection.

    • Two-color indicator light, the lamp current is about 0.2 times cross current value, and the charging status is clear at a glance.
