YaSaLy 4V 6V 12V 14V 24V Battery Charging Power Module 0.2-20A Constant Current

Product description Introduction to synchronous rectification technology: Synchronous rectification is a new technology that uses power MOSFET with low on-state resistance to replace rectifier diode to reduce rectification loss. It can greatly improve the efficiency of dc/dc converter and there is no dead time voltage caused by Schottky barrier voltage. Power MOSFET is a voltage controlled device and its volt ampere characteristics are linear when it is turned on. When using power MOSFET as rectifier the gate voltage and the phase of the rectified voltage are required to be synchronized to complete the rectification function so it is called synchronous rectification. Synchronous rectification technology is to greatly reduce the rectification loss at the output end of switching power supply so as to improve the conversion efficiency and reduce the heating of the power supply itself. Module parameters 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 ferroelectricity) 4V 6V 12V 14V 24V battery charging nickel cadmium nickel hydrogen battery (battery pack) charging solar panels wind turbines Input voltage: 6-40vdc Output voltage: continuously adjustable (1.2-35vdc) below 32V for a long time (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted) Output current: 20A for a long time (if the power tube temperature exceeds 65 ℃ please add a fan to dissipate heat and if the high voltage output is used please reduce the amount) Current limiting range: 0.2-20a (regulating) module. Please add a fan if it exceeds 65 degrees. Low voltage difference: 3V Working frequency: 150kHz Conversion efficiency: it is about 96% higher. The efficiency is related to the pressure difference and the use environment Output ripple: ripple about 50mV (excluding noise) 20m bandwidth (for reference only) input 24V measured Working temperature: -10 ℃ to +75 ℃) (please pay attention to the power tube temperature in actual use. If the temperature is too high please strengthen heat dissipation or reduce the rating for use) Potentiometer adjustment direction: clockwise (increase) counterclockwise (decrease) Output short-circuit protection: there is (instantaneous protection) constant current (the current set constant current value cannot be short circuited for a long time) Input reverse connection protection: none Output anti backflow: none for the load with its own electricity or inductive load 2 pipes need to be added! Wiring mode: terminal block Module size: 60*53*30mm Output current regulation 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 small) connect the LED and adjust the CC potentiometer to the current you need. For battery charging after discharging the battery connect it to the output and adjust CC to the current you need. (when charging be sure to adjust it with the discharged battery because the more remaining battery the smaller the charging current.) Packing list: 1 * power module
