– Module Nature: Synchronous Rectification, Non-Isolated Buck, Constant Current, Constant Voltage 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 battery (battery pack) charging, solar panel, wind generator
– Input voltage: DC 6-40V
– Output voltage: continuously adjustable (1.2-35VDC) below 32V for a long time (suitable for applications where the input voltage is higher than the output voltage cannot be boosted)
– Output current: max. 20A within 15A for a long time (please add a fan to dissipate the power tube temperature over 65 degrees, please derate the high voltage output)
– Current-limiting range: 0.2-20A (adjustment). If the module exceeds 65 degrees, please add a fan.
– Lowest dropout: 3V
– Working frequency: 150KHZ
– Conversion efficiency: up to about 96%, efficiency is related to pressure difference and use environment
– Output ripple: Ripple is about 50mV (no noise included) 20M bandwidth (for reference only) Input 24V measured
– Working temperature: -10 C to + 75 C (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 (the current set constant current value cannot be short-circuited for a long time)
– Input reverse connection protection: None,
– Output anti-reverse perfusion: None, used for self-loaded or inductive load requires an additional 2 pole tube!
– Wiring method: terminal
– Module size: 60 * 53 * 30MM
– Net weight: about 85 grams

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 counterclockwise about 30 turns (that is, set the output current to the minimum), connect the LED, and adjust the CC potentiometer to your desired current. For battery charging, after the battery is discharged, connect it to the output and adjust CC to the current you need. (Be sure to use the discharged battery to adjust it when charging, because the remaining battery capacity is More, the smaller the charging current.)
Wiring instructions:
– OUT +: output positive
– OUT-: output negative
– + IN: input positive
– -IN: input negative
– CV: output voltage adjustment
– CC: output current adjustment
– EN: enable, turn off output at low level; pause, high voltage level is valid
– When the input and output are grounded, the no-load CV outputs constant voltage and CC outputs constant current
