electrolight 300W DC Buck Converter Power Module Output Adjustable 20A Max DC-DC 6-40V step down to 6-40V to 1.2-36V 20A 300W constant current Power Supply Electronic Hobby Kit

Feature: Module properties: synchronous rectifier 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 ferroelectrics), 4V, 6V, 12V, 14V, 24V battery charging, Ni Cd Ni MH battery (battery pack) charging, solar panels, wind power generator. Input voltage: 6-40VDC Output voltage: continuous adjustable (1.2-35VDC) for a long time of less than 32V (applied to the application of the input voltage higher than the output voltage can not be boosted) Output current: Zui 20A 15A (long time within the power tube temperature exceeds 65 degrees with the cooling fan, high voltage output to the amount of use) Limit flow range: 0.2-20A (adjustment) module is more than 65 degrees, please add the fan. Zui low voltage difference: 3V Working frequency: 150KHZ Conversion efficiency: the ZUI high about 96% efficiency is related to the pressure difference and the use environment Output ripple: around 50mV of ripple (without noise) 20M bandwidth (reference only) input 24V Working temperature: -10 C to +75 C) (please pay attention to the temperature of the power pipe in actual use. Please strengthen the heat or reduce the use of the heat.) Potentiometer adjustment: clockwise (increase), counterclockwise (decrease) Output short circuit protection: (instantaneous protection) constant current (current setting constant current value is not long short circuited) Input back protection: No, Output anti - reverse perfusion: No, for load power or inductive load needs additional 2 pole tube! Connection mode: terminal Module size: 60*53*30MM The output current regulation method: 1, adjust the CV potentiometer, according to your load requirements, the output voltage is set to the voltage you need. 2, counter clockwise set the CC potentiometer around 30 circles, (that is, the output current is set to Zui), then LED, adjust the CC potentiometer to the current you need. For battery charging, the battery is fully discharged, the output received again, adjusting CC to the current you need, (for charging for the use of a dead battery transfer is allowed because the battery remaining power increasing, the charging. Input Voltage: 6V to 40V DC(10V to 40V is suggested) Output Voltage: 1.2V to 36V DC Output Current: 20A(max.), 15A(suggested) Efficiency: 95%(24V to 12V, 20A) Output Ripple: ?50mV Wiring Method: Terminal Short Circuit Protection: Self-recovery(cannot short circuit for long time) Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06" VO+: Output positive VO-: Output negative +IN: Input positive -IN: Input negative CV: Output voltage adjustment CC: Output current adjustment EN: Enable, low voltage level shut off output; suspension, high voltage level is effective When input and output is common grounded, no-load CV output constant voltage,CC output constant current
