1. With the airfoil, the heat dissipation is very good, the output is greater (48V input plus fan can be around 1800W when the fan is added).2. The temperature control fan, combined with the hydraulic bearing fan, is well balanced on the noise and heat dissipation. When the load is light, the fan does not rotate, and the load temperature reaches about 60 degrees, and the fan automatically turns. It can effectively reduce noise and prolong life.3. The main pipe insulation board uses high grade alumina, and the thermal conductivity is 10 times as high as insulation pad4. Using 100V 210A TO-247 package tube, the allowance is and the dynamic response is good5. The double size iron silicon aluminum magnetic ring, 4 12 pure copper enameled wire and Rao, low heat, high efficiency.6. New design, the conversion efficiency is up to 981% (for details see the efficiency conversion curve of the following data handbook).7. The 3296W multi loop potentiometer has high adjustment precision and small drift8. Tong wire output current sampling, constant current steady temperature drift small.9. Undervoltage protection is adjustable, it can effectively protect all kinds of batteries, and can also be used in solar cells10. With constant current function, it can be used to boost the battery car, charge the battery and so on11. 3 20A fuse are connected in parallel, which can protect the risk of accidental short circuit of output.12. Three indicator lights: undervoltage, over current, indicator, working state at a glance13. High frequency capacitance is used in both input and output. The output ripple is low, heat is small, and the life is long14. The MLCC ceramic capacitor is added to the input and output, the output ripple is obviously reduced, and about 100 mV at the time of 48V to 72V4A.Application scopeQS-4884CCCV-1800W is designed for lead-acid batteries, lithium batteries, solar cells or booster to boost electric vehicles, battery charging, and has powerful functions.1, for example, the battery of the electric car is 48V can be boosted to 60V to the electric vehicle, which can improve the speed and acceleration of the electric vehicle.2, charge for your electric bicycle. (1: for example, if you have a 12V or 24 idle battery on your hand, you can charge the battery by boosting the supply, which is equivalent to an electric vehicle's charging treasure. Two: at the same time input can also be connected to solar cells, wind, generator and other supplies to the battery charging to increase the endurance of the electric vehicle.)3 can increase the battery voltage to make the electric car run faster, not more than 10V.4 solar panels are boosted and regulated.4 3*50MM long fixed pillarsPin mode:IN input cathode, anode, cathode OUT IN input output, OUT negative outputCV voltage regulation, CC current regulation, UVP input under voltage protection regulationCondition:NewType:Voltage RegulatorSupply Voltage:standardDissipation :1800WModel Number:1800W DC-DC ModuleApplication:Computercolour:redMaterial:Plastic, metalPackage Contents:1*Boost ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
