1. With the airfoil design, heat dissipation is efficient, allowing for higher output power (48V input with fan support can deliver up to approximately 1800W). 2. The temperature-controlled fan, combined with a hydraulic bearing fan, provides a balanced performance between noise and heat dissipation. The fan remains off under light load and automatically activates when the internal temperature reaches around 60 degrees, helping reduce noise and extend lifespan. 3. The main power tube insulation board uses high-grade alumina material, offering thermal conductivity up to 10 times higher than standard insulation pads. 4. Features a 100V 210A TO-247 large-package power transistor, providing ample power headroom and excellent dynamic response. 5. Equipped with dual large-size iron silicon aluminum magnetic rings and 4 strands of 1.2mm pure copper enameled wire windings, ensuring low heat generation and high efficiency. 6. Newly designed circuitry achieves a conversion efficiency of up to 98.1% (refer to the efficiency curve in the product datasheet for details). 7. Uses a 3296W multi-turn precision potentiometer for high adjustment accuracy and minimal drift. 8. Kelvin connection wire for current sensing ensures stable constant current output with low temperature drift. 9. Adjustable under-voltage protection helps safeguard various battery types and is suitable for use with solar panels. 10. Includes constant current mode, ideal for battery charging, vehicle power boosting, and similar applications. 11. Three 20A fuses are connected in parallel to protect against output short circuits. 12. Features three indicator lights for under-voltage, over-current, and power status, providing clear visual monitoring of operational conditions. 13. High-frequency capacitors are used on both input and output sides, resulting in low output ripple, minimal heat generation, and extended service life. 14. MLCC ceramic capacitors are added to input and output circuits, significantly reducing output ripple to approximately 100mV during 48V to 72V @ 4A operation. Application Scope The QS-4884CCCV-1800W is designed for lead-acid batteries, lithium batteries, solar panels, and electric vehicle power boosting, supporting battery charging and voltage step-up functions. 1. Boosts 48V electric vehicle battery voltage to 60V to enhance speed and acceleration. 2. Can charge electric bicycle batteries. For example: - Use a 12V or 24V auxiliary battery to charge another battery via voltage boost, functioning as a portable charging solution. - Simultaneously support input from solar panels, wind generators, or other power sources to charge batteries and extend vehicle range. 3. Increases battery voltage to improve electric vehicle performance, with voltage boost not exceeding 10V. 4. Suitable for boosting and regulating solar panel output.
