The Power Supply Uses Four 63V/470UF High-Frequency Low-Resistance Electrolytic Capacitors For Input, And Three 100v/470uf Electrolytic Capacitors For Output. The 33mm Ultra-High-Power Magnetic Ring Is Wound With Three 1.2mm Pure Copper Wires In Parallel To Prevent Over-Temperature Magnetic Saturation Under Current Conditions.Use A Piece Of Aluminum Heat Sink To Dissipate Heat.And The Heat Sink Has 5015 Fan (5mm x 5mm x 15mm) Installation Holes; The Output Voltage And Current Of The Power Management Chip Are Continuously Adjustable.The Circuit Structure Is Optimized To Make The Power Supply Work More Stable. At The Same Time, The Input Anti-Reverse Connection (Using 150a Mos Anti-Reverse) And Input Low Battery (Low Voltage) Protection Are Added, And The Low Battery Protection Voltage Is Adjustable From 9-50v To Adapt To Various Batteries.When Using Battery Power Supply, There Is No Need To Worry That The Power Module And Battery Will Be Damaged When The Battery Loses Power. Power Description: Since The Maximum Input Current Of This Power Supply Is 20a, The Output Power Is Related To The Input Voltage. The Higher The Input Voltage, The Higher The Power. For Example, The Input Power Of 12V x 20A is 240W. The Input Of 24V x 20A is 480W. This Is The Maximum Power.Due To The Limited Heat Dissipation Area, Please Add A 12V Fan To Dissipate Heat When The Input Voltage Exceeds 10A Or The Output Current Reaches 10A.Pay attention to the following points when using a boost power supply: The voltage of the input power supply must be above 10V. When used in constant current mode and constant voltage, it must be guaranteed that the constant voltage must be higher than the input voltage. (For example, the input voltage of the power supply is 12V and the no-load output voltage is 15V. At this time, connect a 3.2V LED light. This situation is not allowed. At least 4 LED lights connected in series)When using a switching power supply as the input power supply, first connect the input power supply with no load and adjust the voltage. Then pick up the load. (Must that the switching power supply is always working), or adjust the voltage with no load first, then disconnect the switching power supply and then connect the load. Switch on the switching power supply and the power supply module when the switching power supply is turned on. (Because the switching power supply has a rising time when it is turned on. When the voltage is lower than 10V, the chip is not working yet. It is easy to break down the MOS tube.Applications: 1.
