DC 9-35V to DC 1V-35V 80W Automatic Step Down Module Boost Buck CC CV Power Converter Module Adjustable Voltage Regulator

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.
