20A 300W DC to DC CC CV Step Down Charging Board LED Driver Buck Power Converter Module Specification: Module nature: synchronous rectification, non-isolated step-down/constant current/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, nickel-cadmium nickel-metal hydride battery (battery pack) charging, solar panels, wind generators Input voltage: DC 6-40V Output voltage: continuously adjustable (1.2-35V DC) for a long time below 32V (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted) Output current: maximum 20A for a long time within 15A (the power tube temperature exceeds 65 degrees, please add a fan to diate heat, high voltage output please use derating) Current limit range: 0.2-20A (regulation) module, please add a fan if it exceeds 65 degrees. Minimum preure difference: 3V Working frequency: 150kHz Conversion efficiency: up to about 96% efficiency is related to preure difference and use environment Output rple: rple 50mV (no noise) 20M bandwidth (for reference only) at 24V input Working temperature: -10℃~ +75℃ (please pay attention to the temperature of the power tube in actual use, if the temperature is too high, please strengthen the heat diation or derate the use) Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) Output short circuit protection: Yes (instantaneous protection) constant current (current setting constant current value can not be short-circuited for a long time) Input reverse protection: no Output anti-reflow: no, for the load self-charged or inductive load requires an additional 2-pole tube! Wiring mode: terminal block Module size: 60*53*30mm/2.36*2.08*1.18" Net weight: about 85g 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 output current to the minimum), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after the battery is discharged, connect to the output and adjust CC to the current you need. (When charging, you must use the discharged battery to adjust it, because the battery has more power. More, the smaller the charging current.) Wiring instruction: OUT+: output positive OUT-: output negative +IN: input positive -IN: Enter a negative number CV: output voltage regulation CC: Output current adjustment EN: enable, turn off output at low level; pause, valid at high voltage level When the input and output are grounded, CV outputs constant voltage without load, and CC outputs constant current Note: 1. There may be slight size deviations due to manual measurement, different measuring methods and tools. 2. The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor.
