This Module Uses High-Performance Electronic Components, Making The Overall Performance More Stable. Wide Input And Output Voltage Range, High Current And High Power Output; Intelligent Temperature-Controlled Fan, The Module Temperature Rises To Start The Fan About 55 Degrees, And The Module Temperature To About 50 Degrees To Turn Off The Fan; .Input End Mos Tube Anti-Reverse Connection Function, Input The Positive And Negative Poles Will Not Burn Out After The Terminal Connection. Input Low Voltage Protection (Turn Off The Output When The Input Voltage Is Lower Than 20v); There Is An External Output Switch Signal Terminal, Which Is A Standby Switch After Short Circuit The Output Is Constant Voltage And Current, And The Voltage And Current Are Continuously Adjustable. There Is An External Voltage And Current Analog Signal Input Terminal, Which Can Be Controlled By A Microcontroller To Adjust The Voltage And Current. There Is An Output Current Test Point. You Can Use The Mv Block Of A Multimeter To Test The Output Current Setting Value. Module Model: 800W 30A Adjustable Power Supply High-Power Step-Down Module Power Supply Protection: Input Low Voltage Protection (Turn Off The Output When The Input Voltage Is Lower Than 20V) Input Voltage: DC 20-70V Output Voltage: DC2.5-58V Input Current: 20A Max Output Current: 30A Max Output Power: 800W Standby Current: 70mA (Input 24v Output 12v) Different Voltage And Current Are Different Output Ripple: 120MV Conversion Efficiency: 0.92-0.96 Circuit Structure: No Isolation Working Temperature: -20~50 Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Colour: Material:PCB+Metal Size:about 154 x 75mm Package Conten: 1 Module Only the above package content, other products are not included.
