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 previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries). LED Constant Current Driver Use: * Make sure operating current and Max operat.(20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).  Solar panels and wind turbines. Particularly suitable for LED driver.  Output current: adjustable maximum 3A.\u003c\/p\u003e","brand":"O2INEW","offers":[{"title":"Default Title","offer_id":1614581760015,"sku":"O2I-2-292139967286","price":14544.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0929\/2582\/products\/s-l2000__03921_cca7d543-9cb6-410e-a37c-5ea9fc21ffb5.jpg?v=1680111340","url":"https:\/\/order2india.com\/products\/lm2596-dc-dc-adjustable-step-down-power-supply-module-cc-cv-led-driver-7v-35v","provider":"ORDER2INDIA SHOPPING","version":"1.0","type":"link"}
