Power supply current: 5A\u003cbr\u003e2. Input voltage: 5-32V\u003cbr\u003e3. Output voltage: 0.8-30V\u003cbr\u003e4. Switching frequency: 300KHz\u003cbr\u003e5. Working temperature: -40 to 85 degrees Celsius\u003cbr\u003e6. Size: 51x26.3x14mm\u003cbr\u003e7. Note: The IN- (input negative), IN+ (input positive), OUT- (output negative), and OUT+ (output positive) marked on the module must be connected correctly, otherwise the module may be damaged.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e1. The module uses imported high-quality chips, with high efficiency (95% higher), and low heat generation, which can reach 5A current. At the same time, it cooperates with the original TI op amp to control the output current, so that the overall output is very stable.\u003cbr\u003e2. This module uses the original Sanyo filter capacitor with low ESR, which can make the ripple voltage as low as 50mV\u003cbr\u003e3. This module uses machine placement and reflow soldering. At the same time, each module undergoes a two-hour aging test before shipment to ensure high reliability.\u003cbr\u003e4. This module is an adjustable step-down module, and the output voltage can be changed by adjusting the blue adjustable resistor on the module. The input and output voltage difference is 1V, and the small voltage can output 0.8V.\u003cbr\u003e\u003cbr\u003eBattery charging method:\u003cbr\u003e1. Determine the float voltage and charging current of the rechargeable battery you need, and the input voltage of the module;\u003cbr\u003e2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.\u003cbr\u003e3. Measure the output short-circuit current with the 10A current block of a multimeter, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;\u003cbr\u003e4. The default shipping current of the charging lamp is 0.1 times the charging current (constant current value).\u003cbr\u003e5. Adjust the constant voltage potentiometer to make the output voltage reach the float voltage;\u003cbr\u003e6. Connect the battery and try charging.\u003cbr\u003e(Steps 1, 2, 3, 4, and 5 are for the module input to connect to the power supply, and the output does not connect to the battery without load.)\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;\"\u003e0.05kgs \/ 0.11lb\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;\"\u003e10cm * 5cm * 3cm \/ 3.94inch * 1.97inch * 1.18inch\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;\"\u003e200\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;\"\u003e11.00kgs \/ 24.25lb\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;\"\u003e46cm * 32cm * 32cm \/ 18.11inch * 12.6inch * 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: 566 cartons * 200 pcs = 113200 pcs\u003cbr\u003e40HQ: 1314 cartons * 200 pcs = 262800 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":"Bulky Mart","offers":[{"title":"HW-083 Micro USB 5A","offer_id":46148645191921,"sku":"TBD0572171901A","price":617.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/7933\/2849\/files\/TBD0572171901A.jpg?v=1747654947","url":"https:\/\/bulkymart.in\/products\/2-pcs-hw-083-micro-usb-5a-constant-current-and-constant-voltage-led-drive-lithium-ion-battery-charging-power-module-hw-083-micro-usb-5a","provider":"Bulky Mart","version":"1.0","type":"link"}
