Item Type: Buck Converter Material: PCB Purpose: DC DC Buck Converter Input Voltage: DC6-40V Output Voltage: Continuously adjustable (1.2-35VDC) for a long time below 32V (applicable to applications where the input voltage is higher than the output voltage can not be boosted). Output Current: Maximum 20A, within 15A for a long time (when the power tube temperature exceeds 65 degrees, please add a fan to dissipate heat, please derate for high voltage output). Current Limit Range: 0.2-20A (adjustment), then the module exceeds 65 degrees, please add a fan. Minimum Voltage Difference: 3V Working Frequency: 150KHZ Conversion Efficiency: Up to about 96%, the efficiency is related to the voltage difference and the use environment. 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.
