Features: 1. DC-DC Step-Down Module 2. Wide Voltage Input 9-90V 3. Built-In Over-Temperature, Over-Current, And Output Short-Circuit Protection 4. Small Standby Current<br><br>Description: 1. Working Temperature: Industrial Grade (-40℃ To +85℃) 2. The Minimum Voltage Difference Between The Input Voltage And The Output Voltage Is 4V (When The Output Voltage Is 5V, The Input Voltage Is DC9V-90V, When The Output Voltage Is 12V, The Input Voltage Is Dc16V-90V, When The Output Voltage Is 24V, The Input Voltage Is Dc30-90V) 3. Constant Voltage And Constant Current Output 4. The Maximum Output Current Is 3A (That Is, The Constant Current Value Is 3a. When The Customized Voltage Is Greater Than 12V, The Output Current Is Less Than 3a, And The Power Is Not Recommended To Exceed 30W. 12V And 5V Can Reach 3A, And 24V Is 2A) 5. Typical Operating Frequency: 140khz 6. High Efficiency: Up To 95% (The Smaller The Pressure Difference, The Higher The Efficiency) 7. Light Load Frequency Reduction To Improve Light Load Efficiency 8. Built-In Soft Start 9. Output: DC 24V (Output Current Max 3A) Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Material: PCB colour: As Shown<br><br>Package Contents: 1 x Buck Power Module<br><br>Only the above package content, other products are not included.
