Module properties: synchronous rectification non-isolated buck constant current constant voltage module CC CV charging module\u003cbr\u003e2. Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride battery (battery pack) charging, solar panels, wind turbines\u003cbr\u003e3. Input voltage: 6-40VDC\u003cbr\u003e4. Output voltage: continuously adjustable (1.2-35VDC) below 32V for a long time (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted)\u003cbr\u003e5. Output current: maximum 20A, long-term within 15A (please add a fan to dissipate heat when the power tube temperature exceeds 65 degrees, and use a reduced rating for high voltage output)\u003cbr\u003e6. Current limiting range: 0.2-20A (adjustment) please add a fan if the module exceeds 65 degrees\u003cbr\u003e7. Low voltage difference: 3V\u003cbr\u003e8. Operating frequency: 150KHZ\u003cbr\u003e9. Conversion efficiency: about 96% high, efficiency is related to voltage difference and use environment\u003cbr\u003e10. Output ripple: ripple about 50mV (excluding noise) 20M bandwidth (for reference only) input 24V measured\u003cbr\u003e11. Working temperature: -10 to +75 degrees Celsius (please pay attention to the power tube temperature in actual use, if the temperature is too high, please increase heat dissipation or use it at a reduced rating)\u003cbr\u003e12. Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)\u003cbr\u003e13. Output short circuit protection: yes (instantaneous protection) constant current (the current constant current value cannot be short-circuited for a long time)\u003cbr\u003e14. Input reverse connection protection: no\u003cbr\u003e15. Output anti-reverse current: no, for loads with self-power or inductive loads, an external diode is required!\u003cbr\u003e16. Wiring method: Wiring terminal\u003cbr\u003e17. Size: 60x53x30mm\u003cbr\u003e18. Weight: about 85 grams\u003cbr\u003e\u003cbr\u003eOutput current adjustment method:\u003cbr\u003e1. Adjust the CV potentiometer to set the output voltage to the voltage value you need according to your load requirements\u003cbr\u003e2. Set the CC potentiometer counterclockwise for about 30 turns (that is, set the output current to a small value), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, discharge the battery, then connect it to the output, and adjust CC to the current you need (when used for charging, you must use a discharged battery to adjust it accurately, because the more power left in the battery, the smaller the charging current)\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv class=\"params_begin\"\u003eSpecification:\u003c\/div\u003e\u003cdiv style=\"border-top: 1px solid #e0e0e0; width: 100%;\"\u003e\u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e  \u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 15%;\"\u003ePackage Weight\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 0;\"\u003e\n\u003cdiv style=\"border-bottom: 1px dashed #e0e0e0; width: 100%;\"\u003e  \u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 25%;\"\u003eOne Package Weight\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 5px;\"\u003e0.10kgs \/ 0.23lb\u003c\/td\u003e\n\u003c\/tr\u003e  \u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border-bottom: 1px dashed #e0e0e0; width: 100%;\"\u003e  \u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 25%;\"\u003eOne Package Size\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 5px;\"\u003e7cm * 7cm * 6cm \/ 2.76inch * 2.76inch * 2.36inch\u003c\/td\u003e\n\u003c\/tr\u003e  \u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border-bottom: 1px dashed #e0e0e0; width: 100%;\"\u003e  \u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 25%;\"\u003eQty per Carton\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 5px;\"\u003e175\u003c\/td\u003e\n\u003c\/tr\u003e  \u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border-bottom: 1px dashed #e0e0e0; width: 100%;\"\u003e  \u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 25%;\"\u003eCarton Weight\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 5px;\"\u003e18.60kgs \/ 41.01lb\u003c\/td\u003e\n\u003c\/tr\u003e  \u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border-bottom: 1px dashed #e0e0e0; width: 100%;\"\u003e  \u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 25%;\"\u003eCarton Size\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 5px;\"\u003e51cm * 37cm * 32cm \/ 20.08inch * 14.57inch * 12.6inch\u003c\/td\u003e\n\u003c\/tr\u003e  \u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"params_prop last_prop\"\u003e  \u003ctable border=\"0\" style=\"margin-bottom: 0; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: none; padding: 5px; width: 25%;\"\u003eLoading Container\u003c\/td\u003e\n\u003ctd style=\"border: none; padding: 5px;\"\u003e20GP: 441 cartons * 175 pcs = 77175 pcs\u003cbr\u003e40HQ: 1025 cartons * 175 pcs = 179375 pcs\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e  \u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e  \u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cdiv style=\"border-top: 1px solid #e0e0e0;\"\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Trustpick","offers":[{"title":"20A","offer_id":43533674774587,"sku":"TBD0605261201A","price":123000.0,"currency_code":"VND","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/9723\/9611\/files\/TBD0605261201A.jpg?v=1779364206","url":"https:\/\/vi.trustpick.com\/products\/20a-300w-high-power-synchronous-rectification-power-supply-step-down-module-20a","provider":"Trustpick","version":"1.0","type":"link"}
