High power electronic components, stable and reliable. _x000D_ 5. Adopt aluminum substrate PCB with good thermal conductivity. _x000D_ 6. Input MOS tube prevents from reverse connection. _x000D_ 7. Mainly used for solar street light drive, LED drive, car power supply, solar charging power, battery charging, etc. _x000D_ _x000D_ Specification: _x000D_ Input Voltage: DC 10-36V _x000D_ Input Current: 5A(Max) _x000D_ Output Voltage: DC 10-36V (constant voltage 2.5-36V) _x000D_ Output Current: 0-5A (constant current 0.3-5A) _x000D_ Output Power: 75W(Max) _x000D_ Conversion Efficiency: 88%-90%(related to input/output voltage) _x000D_ Operating Temperature: -20~50 _x000D_ Weight: Approx. 47g/1.6oz _x000D_ _x000D_ _x000D_ Module Instructions: _x000D_ 1. VIN+ is the input positive, and VIN- is the input negative. _x000D_ 2. OUT+ is the output positive, OUT- is the output negative. _x000D_ 3. Constant voltage adjustable range: DC2.5V-36V (clockwise decrease, counterclockwise increase), please adjust no-load output voltage to what the load requires, then connect the load (You should adjust the constant current to the maximum at constant voltage mode). _x000D_ 4. Constant current adjustable range: 0.3A-5A (clockwise decrease, counterclockwise increase). First adjust no-load output voltage to what the load requires (No-load voltage should be 1-2V higher than load voltage ), adjust the current to minimum, then slowly adjust the current to what the load requires. _x000D_ 5. When the output exceeds 35W, please strengthen the heat dissipation. _x000D_ 6. When using a switching power supply or other secondary power supply to power this module, please ensure that the power supply power is over twice of this module power. _x000D_ _x000D_ Package list: _x000D_ 1 * Step-Up Down Power Supply _x000D_ _x000D_ Note: _x000D_ 1. The input/output voltage and current must not exceed the maximum value during operation to avoid damage to the power supply. _x000D_ 2. Pay attention to ventilation and heat dissipation when working for a long time to extend the service life of the power supply.
