Power Module Synchronous Rectifier Buck CC CV Converter High Power LED Drive 300W 20A

Brand

<li>1、The input and output adopt high-frequency and low-impedance electrolytic capacitors, with low ripple and stable output power. 2、The buck converter has a wide input voltage range of 6V‑40V and can accurately adjust the output voltage and current. 3、The buck power supply module has 2 heat sinks and uses high‑quality aluminum materials for good heat dissipation. 4、The output voltage is continuously adjustable, with output short-circuit protection, safer and more efficient operation. 5、Commonly used for lithium battery charging, battery charging, nickel-cadmium nickel-hydrogen battery charging, solar panels, wind generators, etc. Item Type: Power Module Material: PCB + Aluminum Module Nature: Synchronous rectification, non-isolated buck constant current constant voltage module, CC CV charging module 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: 6-40VDC Output Voltage: Continuously adjustable (1.2-35VDC), 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, within 15A for a long time (the temperature of the power tube exceeds 65℃, please add a fan to dissipate heat, and please derate for high-voltage output) Current Limit Range: 0.2-20A (regulation) module, please add a fan if it exceeds 65℃ 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 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 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) Input Reverse Connection Protection: None Output Anti-reflow: None, for the load self-charged or inductive load requires an additional 2-pole tube Wiring Mode: 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 to about 30 turns counterclockwise (that is, set the output current to low), 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.) 1 x Power Module<li>
