800W DC-DC Buck Converter Step-Down Power Supply Module in 20-70V Out 2.5-58V Item Description Parameters: 1. Product Name: high power DC step-down module power supply. 2. Product model: ap-d5830a. 3. Input voltage: dc20v-70v. 4. Input current: 20A max. 5. Output voltage: 2.5v-58v adjustable. 6. Output current: 0.1-30a adjustable. 7. Output power: 800W max. 8. Conversion efficiency: 93-97% (efficiency is related to input and output voltage and current). 9. Circuit structure: non isolated (Buck). 10. Working temperature: - 20 ~ 60. Main features: 1. High conversion efficiency. 2. High power original device. 3. High power and high electricity diferro silicon aluminum magnetic ring. 4. Input MOS tube anti reverse connection (input is not afraid of reverse connection). 5. Output constant voltage and current adjustable. 6. There is output over-current protection indicator. 7. There is an output indicator. 8. High power profile aluminum radiator. 9. Intelligent temperature control fan for heat dissipation. 10. High reliability and stable operation. Main uses: 1. High power solar street lamp drive. 2. All kinds of LED lighting constant current drive. 3. Power supply for vehicle and various mobile devices. 4. DIY adjustable constant voltage and current power supply. 5. Solar charging power supply. 6. Charge various batteries. Instructions: 1. Input and output poles are marked in Chinese. 2. Adjustable range of output constant voltage: dc2.5v-58v (turn down clockwise and turn up anticlockwise). Please turn on the load after adjusting the output voltage to the voltage you need when the output is no-load (when the constant voltage power supply, adjust the constant current to 1.2-1.5 times larger than the load current), 3. Adjustable range of output constant current: 0.1a-30a (small clockwise and large anticlockwise). First adjust the output voltage with no load (the load voltage in constant current time and space should be 2-3v higher than the load voltage), adjust the constant current to the minimum, then connect the load and input a ammeter in series at the output, and slowly adjust the current to the current you need. 4. When there is output, the output indicator is on, matters needing attention: 1. When the input and output voltage is higher than 36V, please pay attention to the safety of power consumption and prevent electric shock. 2. When working with high current, please tighten the screws of the terminal. 3. The input and output voltage and current shall not exceed the maximum value during operation to avoid damaging the power supply. 4. When working at full load for a long time, pay attention to ventilation and heat dissipation to extend the service life of the power supply. 5. Pay attention to dust-proof and moisture-proof.
