915 Generation 2Pcs 20A 300W High-Power Buck Converter Module DC

Detailed Information About The Product:

Module properties: synchronous rectification, non-isolated buck, constant current and constant voltage module, CC CV charging module
Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, Ni-Cd Ni-MH battery (battery pack) charging, solar panels, wind turbines
Input voltage: 6-40VDC; Output voltage: continuously adjustable (1.2-35VDC) for a long time below 32V (suitable for applications where the input voltage is higher than the output voltage and cannot be boosted)
Output current: maximum 20A, within 15A for a long time (please add a fan to dissipate heat if the temperature of the power tube exceeds 65 degrees, and use derating for high voltage output)
Current limiting range: 0.2-20A (adjustment) If the module exceeds 65 degrees, please add a fan. Low dropout: 3V; Working frequency: 150KHZ

Conversion efficiency: about 96% higher, the efficiency is related to the pressure difference and the use environment
Output ripple: about 50mV ripple (no noise) 20M bandwidth (for reference only) input 24V measured
Operating temperature: -10℃ to +75℃) (Please pay attention to the temperature of the power tube in actual use, if the temperature is too high, please strengthen the heat dissipation or derate the use)
Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
Input reverse polarity protection: none,
Output anti-backflow: none, for self-charged or inductive loads, an external 2-pole tube is required!
Wiring method: terminal block
Output current adjustment method:
1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.
2. Set the CC potentiometer counterclockwise for about 30 turns (that is, set the outputcurrent to be small), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after the battery is fully discharged, connect it to the output, and adjust the CC to the current you need. The more, the smaller the charging current.)
size: 60 x 53 x 30MM
