DC-DC Automatic Step Up Down Power Supply Module Voltage Current Adjustable YEMAA

Features: 1. Automatic step-up/step-down output voltage. 2. Output constant voltage/current, continuously adjustable. 3. High conversion efficiency up to 90%. 4. High power electronic components, stable and reliable. 5. Adopt aluminum substrate PCB with good thermal conductivity. 6. Input MOS tube prevents from reverse connection. 7. Mainly used for solar street light drive, LED drive, car power supply, solar charging power, battery charging, etc. 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, OUT- is the output negative. 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). 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. 5. When the output exceeds 35W, please strengthen the heat dissipation. 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. Package list: 1 * Step-Up Down Power Supply Note: 1. The input/output voltage and current must not exceed the maximum value during operation to avoid damage to the power supply. 2. Pay attention to ventilation and heat dissipation when working for a long time to extend the service life of the power supply.
