A. It adopts airfoil heat dissipation, with good heat dissipation effect and greater output power (when inputting 48V and adding a fan, the power can reach about 1800W). B. The combination of a temperature - controlled fan and a hydraulic fan achieves a balance between noise and heat dissipation. When the load is light, the fan does not rotate; when the load temperature reaches about 60 degrees, the fan automatically turns on and rotates. It can reduce noise and extend the service life. C. The insulating plate of the main power tube is made of alumina, and its thermal conductivity is 10 times that of the insulating pad. D. It uses 100V 210A TO - 247 packaged power tubes, with power margin and good dynamic response. E. It has double - sized iron - silicon - aluminum magnetic rings, using four 1.2 pure copper enameled wires, which generate low heat and have high efficiency. F. With a design, the conversion efficiency is as high as 98.1%. G. It is equipped with a 3296W multi - turn potentiometer, with high adjustment accuracy and [part of the original text is missing here]. H. It has a constant - current function and can be used for battery boosting, battery charging, etc. I. Three 20A fuses are connected in parallel on the input side, which can reduce the risk of accidental short - circuit at the output. J. There are three indicator lights: under - voltage, over - current, and power indicator lights, making the working status clear at a glance. Product Name: 1500W Boosting Constant - Current Module Input Voltage: DC 10 - 60V Output Voltage: Continuously adjustable from 12 - 90V Output Current: Maximum 20A. If it exceeds 15A, it is recommended to strengthen heat dissipation (it is related to the input - output voltage difference. The larger the voltage difference, the smaller the output current). Constant - Current Range: 0.8 - 20A (±0.3A) Input Reverse - Connection Protection: Yes (150A power MOS reverse - connection protection) Low - Battery Protection: Yes (adjustable from 8 - 50V) - [the original expression here is incomplete] Operating Temperature: - 40 ~ +85 degrees (it is recommended to strengthen heat dissipation when the temperature is too high) Operating Frequency: 150KHz Color: Red Material: PC + Metal Dimensions: Length 130mm, Width 52mm, Height 84mm (including copper columns and fan) Weight: 490 grams Packaging Contents: One module Only the above packaging contents are included, and other items are not included. Note: Light and different displays may cause the color of the item in the picture to vary slightly from the actual object. The measurement error is allowed to be ±1 - 3cm.
