Features 1、Volt Buck Board: This DC to DC converter module has a wide input voltage range from 6V to 40V, very useful. 2、Accurate to Set: Ensuring high accuracy in setting output voltage and providing constant current as well. 3、Double MOS Tube: Equipped with 75V 80A high current dual MOS tube, works with stability and reliability. 4、High Efficiency: Measured at 20A, the converter can transform 24V to 12V, and the efficiency can get to 96%. 5、Reliable Output: Use high frequency and low impedance electrolytic capacitors, with low ripple and stable output power. Specification Item Type: Buck Converter Material: PCB Purpose: DC DC Buck Converter Current Limit Range: 0.2-20A (adjustment), then the module exceeds 65 degrees, please add a fan. Working Frequency: 150KHZ Output Ripple: Ripple around 50mV (no noise) 20M bandwidth (for reference only) 24V input measured. Working Temperature: -10℃ to +75℃ (Please pay attention to the temperature of the power tube in actual use, and if the temperature is too high, please strengthen the heat dissipation or derate the use). Potentiometer Adjustment Direction: clockwise (increase), counterclockwise (decrease). Output Short Circuit Protection: Yes (instantaneous protection) constant current (currently set constant current value can not be short circuited for a long time). Wiring Mode: Terminal Scope of Application: For high power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel cadmium nickel metal hydride battery (battery pack) charging, solar panels, wind turbines.
