TECNOIOT 1pcs DC 9 35V to 1 80W Step Up Down Buck Boost Converter Power Supply Module

【80WUPDOWN】QS-1212CCBD-80W module is designed for high-power LED power supply, touch battery charging, automotive power supply, car charger for lead-acid batteries, lithium batteries, solar batteries or power supply buck-boost, the function is very powerful. 【Features-1】✔1. With airfoil cooling, the cooling effect is significantly improved, the output power is greater (28V input plus fan when the power can be about 120W).✔2. New design, conversion efficiency up to 90.5% (see data sheet efficiency conversion curve below for details).✔3. Large-sized Sendust ring, using two 1.2 copper enameled wire and Rao, fever low, high efficiency. 【Features-2】✔4. Brand 3296W multi-turn potentiometer, high precision, small drift.✔5. Using an independent reference IC, a number of alloy sampling resistance, constant current stability temperature drift small.✔6. Undervoltage protection adjustable, can effectively protect a variety of batteries, solar cells can also be used.✔7. With constant current function, can be used for high-power LED lights, battery charging and so on. 【Features-2】✔8. With over-temperature protection, you can effectively protect the power tube overheating, the protection of the use of power-down protection mode, off the type of non-directly to the battery charging or LED power supply, when the temperature will slowly reduce the output power, when the temperature drops Automatic recovery.✔9. Output with short circuit protection, eliminating the shortcomings of the boost module without short circuit protection. 【Features-3】✔10. Two-color light, turn light current is about 0.2 times the cross-flow value, charging status at a glance.✔11. Added MLCC ceramic capacitors, the output ripple significantly reduced at 12V 2A about 200 millivolts.✔12. Very suitable for the car to 12.6V 14.4V lithium battery can be input 10-30V output stable at 12.6V, 14.4V, 14.6V, 16.8V and so on
