300W 20A DC-DC Buck Converter Step Down Module Constant Current LED Driver Power Step Down Voltage Module Electrolytic Capacitor PARYT

300W 20A DC-DC Buck Converter Step Down Module Constant Current LED Driver Power Step Down Voltage Module Electrolytic Capacitor Product Description: What is synchronous rectification? Synchronous rectification is a new technology that uses a dedicated power MOSFET with very low on-state resistance to replace the rectifier diode to reduce rectification losses. It can greatly improve the efficiency of DC/DC converter and there is no deadband voltage caused by Schottky barrier voltage. Product Features: 6-40V wide voltage input Synchronous rectification 97% high efficiency Continuously adjustable constant voltage and constant current outputs Two 85V 80A high current MOS tubes 23M ferrosilicon aluminum 3 0.8MM pure copper wire parallel winding Product parameters: Module nature: synchronous rectifier non-isolated buck constant current constant voltage module CCCV 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 batteries (battery packs) charging solar panels, wind turbines. Input voltage:6-40VDC Output voltage: continuously adjustable (1.2-35VDC) long time 32V or less (for applications where the input voltage is higher than the output voltage can not be boosted) Output current: maximum 20A long time within 15A (power tube temperature over 65 degrees, please add a fan to dissipate heat, high voltage output, please reduce the amount of use) Current limit range: 0.2-20A (adjustable) module over 65 degrees, please add a fan. Minimum voltage difference:3V Operating frequency: 150KHZ conversion efficiency: the highest about 96% efficiency with the pressure difference and the use of environmental issues Output ripple: ripple 50mV or so (excluding noise) 20M bandwidth (for reference only) measured at 24V input Operating temperature: -10 to +75 ) (the actual use of please note that the power tube temperature, the temperature is too high, please strengthen the heat dissipation or derating use) Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) Output short-circuit protection: Yes (instantaneous protection) constant current (the current set constant current value can not be a long time short-circuit) Input reverse connection protection: No Output anti-reverse irrigation: No, for load self-powered or inductive loads need to add 2 poles! Wiring: terminal module size: 60 * 53 * 30MM Scope of application. High-power LED constant current driver, lithium battery charging (including ferroelectric) 4V, 6V, 12V, 24V battery charging, nickel-cadmium nickel-metal hydride battery (battery pack) charging, solar panels, wind turbines. Product use: Output current adjustment method. 1, adjust the CV potentiometer, according to your load requirements, set the output voltage to the voltage value you need. 2Set the CC potentiometer counterclockwise for about 30 turns (i.e., set the output current to the minimum), connect the LED, adjust the CC potentiometer to the current you need. For battery charging, after discharging the battery, and then connected to the output, adjust the CC to your desired current ((for charging must be used to discharge the battery to adjust only accurate, because the battery left in the more power the charging current is smaller.) _x000D_ _x000D_
