Description: Applications: High-power LED constant current driver, lithium battery charger (including ferroelectric) 4V, 6V, 12V, 14V, 24V battery charger, Nickel cadmium, nickel metal hydride batteries charger, solar panels and wind turbines. Features: Non-isolated step-down constant current, constant voltage module (CC CV) charging module Input voltage: 7-35V Output voltage: continuously adjustable (1.25-30V) Output current: Max 3A. (more than 15W, please install the heat sink.) Constant current range :0-3A(adjustable) Minimum Voltage difference: 2V Output power: natural cooling 15W. Conversion efficiency: up to 90% (The highest is 90%, output voltage higher, higher the efficiency) Operating temperature: Industrial grade (-40 ℃ to +85 ℃) (ambient temperature exceeds 40 degrees, lower power use, or add one heatsink) Full load temperature rise: 45 °C No-load Current: Typical 10mA (12V switch to 4.2V) Load regulation: ± 1% Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Potentiometer adjustment direction: clockwise (increase), counter clockwise (decrease) Indicator: when charging is Red, fully charged is Green. Output short circuit protection: Yes, constant current (constant current value of the current settings) Input reverse polarity protection: Yes. Connection mode: welded, plus pin can be directly soldered on the PCB to matching pin, radiator, shell. Size: ultra-small size 48 (L) * 24 (W) * 11.4 (H) mm (without potentiometer) Battery charge use: Make sure of the voltage and current of the battery you need to charge. Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value. Charge transfer lamp current default value is 0.1 times of the charging current (constant current value), For lamp current adjustment, please turn potentiometer adjustment; Connected to the battery, try charging. (1, 2, 3, 4 steps to connect the power module input and output load does not take batteries.) LED constant current driver usage: Make sure operating current and Max operating Voltage of the LED you need to drive. Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage. Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected LED operating current. Join LED, test. (1, 2, 3, 4 steps to connect the power module input and output load does not take LED.)
