1pc Dc-dcled Driver Lm2596 Step-down Adjustable Power Supply Module Cc-cv New Description: 100% brand new and high quality Quantity:1pc Weight:13 g Color: as picture show Size:46mmx23mmx10mm/1.81"x0.91"x0.39"(inch) (approx) Features: 1.Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full); 2. Increased input reverse polarity protection diode; 3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%). Particularly suitable for LED driver *High-power LED constant current drive *Lithium battery charger (including ferroelectric) *4V, 6V, 12V, 14V, 24V battery charger *Nickel cadmium, nickel metal hydride battery pack charger *Solar panels and wind turbines Specifications: *Module Properties: non-isolated constant current and voltage module *Rectification: non-synchronous rectification *Input voltage: 7V-35V *Output voltage: 1.25V-30V *Output current: adjustable maximum 3A *Conversion efficiency: 92% (the highest) *Switching frequency: 150KHz *Output ripple: 50mV (max) 20M bandwidth *Load Regulation: 0.5% *Voltage Regulation: 2.5% *Operating Temperature: -40 to +85 Battery 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 * Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease) *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 * The charge current of transfer lamp is default 0.1 times of the charging current (constant current value) * Connected to the battery and try to charging (for previ
