KNACRO DC to DC Converter Power Adapter 5-32V to 0_8-30V 5A Constant Current LED Driver Battery Charging Module Power Supply Regulator

Module Properties: non-isolated step-down module. Rectification: Non-synchronous rectification. Input voltage: 5V-32V. Output voltage: 0.8V-30V. Output Current: Adjustable maximum 5A. Conversion efficiency: 95% (maximum). Switching frequency: 300KHz. Output ripple: 50mV (maximum) 20M bandwidth. Load regulation: ± 0.5%. Voltage regulation: ± 2.5%. Working temperature: -40 ? to + 85 ?. Size: 51 * 26.3 * 14 (L * W * H) (mm). Weight: 18.6g. Battery recharging methods: 1. Determine whether you need to recharge the battery float voltage and charge current, input voltage of the module; 2. Adjust the constant voltage potentiometer, the output voltage is regulated to about 5V. 3. 10A current with a multimeter to measure the output short-circuit current block, while adjusting the constant current potentiometer allows the output current reaches a predetermined charge current value; 4. Charge turn lamp current default shipping is 0.1 times the charging current (current value). 5. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage; 6. connected to the battery, try charging. (1,2,3,4,5 step input module connected to the power supply, output load is not connected to the battery.)
