1. With the airfoil design, heat dissipation is highly effective, allowing for greater output power (48V input with fan can support up to approximately 1800W). 2. Temperature-controlled fan combined with a hydraulic bearing fan provides balanced noise and thermal performance. The fan remains off under light loads and automatically activates when the internal temperature reaches approximately 60 degrees, helping reduce noise and extend lifespan. 3. The main power tube insulation board uses high-grade alumina material with thermal conductivity 10 times higher than standard insulation pads. 4. Features a 100V 210A TO-247 large package power transistor, offering 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 for low heat generation and high efficiency. 6. Newly designed circuitry achieves a conversion efficiency of up to 98.1% (refer to efficiency curve in product datasheet). 7. Uses a 3296W multi-turn precision potentiometer for high adjustment accuracy and minimal drift. 8. Current sampling via copper wire ensures stable constant current output with low temperature drift. 9. Adjustable undervoltage protection helps safeguard various battery types and is suitable for use with solar cells. 10. Includes constant current functionality, ideal for battery boosting, charging applications, and electric vehicle power enhancement. 11. Three 20A fuses connected in parallel provide protection against output short circuits. 12. Features three indicator lights for undervoltage, overcurrent, and power status, enabling clear visibility of operational state. 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 at input and output stages, significantly reducing output ripple to around 100mV during 48V to 72V/4A operation. Application Scope The QS-4884CCCV-1800W module is designed for lead-acid batteries, lithium batteries, solar cells, and DC power boosting applications such as electric vehicle power enhancement and battery charging. 1. Can boost a 48V electric vehicle battery to 60V, improving vehicle speed and acceleration. 2. Suitable for charging electric bicycles. For example, a 12V or 24V idle battery can be charged using this boost power supply, functioning as a portable charging solution. The input can also be connected to solar panels, wind generators, or other power sources to charge batteries and extend electric vehicle range. 3. Capable of increasing battery voltage to enhance electric vehicle performance, with voltage increase not exceeding 10V. 4. Can boost and regulate output from solar panels.
