DC-DC Buck Converter 7-35V to 1.25-30V 15W CC/CV Module For LED Drive&Charging Description Applications: High Power LED constant current Driver, Lithium battery (including ferroelectric) Charging, 4V?6V?12V?14V?24V battery charging, Nickel cadmium nickel hydrogen battery charging, Solar panels, Wind turbines. Features: Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module Input voltage:7-35V Output voltage:1.25-30V(Continuously adjustable) Output current:Max 3A(high than 15W need heat sink) Constant current range:0-3A(Adjustable) Transfers lamp electric current:Constant current value * 0.1. The lowest voltage difference:2V Output power: natural cooling 15W, add heat sink 25W. Conversion efficiency:Max 90%(the higher output voltage,the higher efficiency) Output ripple:20M bandwidth (only for reference) Input 12V output 5V 3A 60mV(MAX) Operating temperature: Industrial (-40 ℃ to +85 ℃) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation) Full load temperature rise:45℃ No-load current: typical 10mA(12V to 4.2V) Load regulation:±1% Voltage Regulation:±0.5% Constant current accuracy and temperature:The actual test, the module temperature changes from 20 degrees to 100 degrees, the constant current value varies by less than 1% (constant value 1A) Dynamic response speed:5% 200uS Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) near the potentiometer input is a voltage regulator (CV), near the potentiometer output is a current regulator (CC). Indicator: two-color indicator, when charging indicator is red, charging is completed indicator is green(no load connect then the indicator is green). Output short circuit protection:Yes,Constant current value. Input reverse polarity protection:Yes. Output backflow prevention:Yes.Series connection backflow prevention diode in internal. Wiring: Welding,Plus pin can be directly soldered to the PCB. Size:49(L)*23.4(W)*11.4(H) mm(Exclude potentiometer) Battery charging method: You need to Confirm the battery float voltage and charging current, the input voltage of the module. Adjust the constant voltage potentiometer, the output voltage adjust to about 5V. Use multimeter 10A measuring the output short-circuit current,then adjust the constant current potentiometer to make the output current reaches a predetermined charge current value. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage. Connected to the battery, try to charge (1, 2, 3, 4 steps for the module input power, output no-load is not connected to the battery) LED constant current drive method: You need to Confirm LED drive working current and maximum operating voltage. Adjust the constant voltage potentiometer, the output voltage adjust to about 5V. Use multimeter 10A measuring the output short-circuit current,then adjust the constant current potentiometer to make the output current reaches LED working current. Adjust the constant voltage potentiometer to make the output voltage reaches LED maximum operating voltage. Connect LED,Try. (1, 2, 3, 4 steps for the module input power, output no-load is not connected to the LED lights) Package included: 1 x LM2596 DC-DC Buck Converter Module Payment We only accept PayPal.
