Product parameters
● 1. Module nature: synchronous rectifier non-isolated step-down constant current constant voltage
● 2. Module CC-CV charging module
● 3. Scope of use: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel chrome nickel metal hydride battery (battery pack) charging, solar panel, wind turbine
● 4. Input voltage: 6-40VDC
● 5. Output voltage: continuously adjustable (1.2-35VDC). It needs to be controlled below 32V when used for a long time (applicable to applications where the input voltage is higher than the output voltage, and cannot be boosted
● 6. Output current: maximum 20A, long time use, need to be controlled below 15A (if the power tube temperature exceeds 65 ℃, please add fan heat, and reduce the rating for high voltage output)
● 7. Current limiting range: 0.2-20A (regulating) If the module exceeds 65 ℃, please add a fan
● 8. Lowest differential pressure: 3V
● 9. Operating frequency: 150KHz
● 10. Conversion efficiency: the highest efficiency is about 96%, which is related to the pressure difference and operating environment
● 11. Output ripple: about 50mV (without noise), 20M bandwidth (for reference only), measured by input 24V
● 12. Working temperature: - 10 ℃~+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
● 13. Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
● 14. Output short-circuit protection: with (instantaneous protection) constant current (the current set constant current value cannot be short-circuited for a long time)
● 15. Input reverse connection protection: None
● 16. Output anti-backflow: None, for load with power or inductive load, the additional diode is required
● 17. Wiring mode: terminal block
● 18. Module size: 60 * 53 * 30mm
Product use
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 (set the output current to the minimum), connect the LED, and adjust the CC potentiometer to the current you need. For charging the battery, after the battery is discharged, connect it to the output, and adjust the CC potentiometer to the current you need. (For charging, you must use the discharged battery to adjust it accurately, because the more the remaining battery power, the smaller the charging current.)
Package Include
● 1 * Step Down Buck Converter
