1. With the airfoil, the heat dissipation is very good, the output power is greater (48V input plus fan power 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 power pipe insulation board uses high grade alumina, and the thermal conductivity is 10 times as high as the ordinary insulation pad.4. Using 100V 210A TO-247 large package power tube, the power allowance is large and the dynamic response is good.5. The double large size iron silicon aluminum magnetic ring, 4 1.2 pure copper enameled wire and Rao, low heat, high efficiency.6. New design, the conversion efficiency is up to 98.1% (for details see the efficiency conversion curve of the following data handbook).7. The 3296W multi loop potentiometer has high adjustment precision and small drift.8. 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 cells.10. With constant current function, it can be used to boost the battery car, charge the battery and so on.11. 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, power indicator, working state at a glance.13. High frequency capacitance is used in both input and output. The output ripple is low, heat is small, and the life is long.14. 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 power 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 power 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 power 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 power 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 Power:1800WModel Number:1800W DC-DC ModuleApplication:Computercolour:redMaterial:Plastic, metalPackage Contents:1*Boost Power 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.
