Features
1. The airfoil has a significant heat dissipation effect and a larger output power;
2. New design, conversion efficiency up to 90.5% (for details, see the data sheet efficiency conversion curve below);
3. Independent reference IC, multiple alloy sampling resistors, constant current and stable temperature drift;
4. The undervoltage protection is adjustable, which can effectively protect various batteries and can also be used for solar cells;
5. With constant current function, it can be used for high-power LED lights, charging batteries, etc.
6. 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.
7. The output has short circuit protection, which eliminates the disadvantages of the boost module without short circuit protection.
8. Two-color indicator light, the lamp current is about 0.2 times cross current value, and the charging status is clear at a glance.

Precautions
(1) The wire length of 12V is less than 1 meter. The wire is not less than 1.5 square. If the length is more than 1 meter, please increase the wire.
(2) When the module works in high power, high temperature, plus the shell, please install the fan. Do not add fans for low power. Make sure the temperature of the module heat sink does not exceed 80 degrees.
(3) In use, the input cannot be reversed The input cannot exceed the maximum safe voltage.
(4) The discharge voltage of the 12V battery must not be lower than 10.5V, and the discharge voltage of the lithium battery used in series (3.7kV in a single cell) must not be lower than 2.7V.
(5) IN+ input positive, IN- input negative, OUT+ output positive, OUT- output negative.
