Welcome to our shop! Description: This Step-Up Down Power Supply features automatic step-up/step-down output voltage, with a continuously adjustable output constant voltage/current. It has a high conversion efficiency of up to 90% and is equipped with high power electronic components for stability and reliability. The module also adopts an aluminum substrate PCB with good thermal conductivity for efficient heat dissipation. It is mainly used for solar street light drive, LED drive, car power supply, solar charging power, battery charging, and more. Specification: - Input Voltage: DC 10-36V - Input Current: 5A(Max) - Output Voltage: DC 10-36V (constant voltage 2.5-36V) - Output Current: 0-5A (constant current 0.3-5A) - Output Power: 75W(Max) - Conversion Efficiency: 88%-90% (related to input/output voltage) - Operating Temperature: -20~50℃ - Weight: Approx. 47g/1.6oz Module Instructions: 1. VIN+ is the input positive, and VIN- is the input negative. 2. OUT+ is the output positive, and OUT- is the output negative. 3. Constant voltage adjustable range: DC2.5V-36V (clockwise decrease, counterclockwise increase). Adjust the no-load output voltage to match the load requirements, then connect the load. 4. Constant current adjustable range: 0.3A-5A (clockwise decrease, counterclockwise increase). Adjust the no-load output voltage to be 1-2V higher than the load voltage, then adjust the current to the load requirements. 5. Strengthen heat dissipation when the output exceeds 35W. 6. When using a switching power supply or other secondary power supply, ensure that the power supply power is at least twice the power of this module.
