Aluminum alloy black coating heat sink: The black coating helps absorb heat, improves heat dissipation efficiency, and effectively prevents overheating of the Schottky and XL6012 chips, which could affect conversion efficiency and normal circuit operation. European-style large terminals: Large terminals conduct current more efficiently and safely; internal interlocking structure ensures secure wiring; deep soldering of pins. Dual XL6012 boost chips combined with four MBR20100CT chips provide stable boost. High conversion efficiency and stable heat dissipation. Can continuously output 5A 24V power 120W. Dual copper core large inductor: The inductor coil has a current-limiting effect on AC. It can form a high-pass or low-pass filter, phase-shifting circuit and resonant circuit with resistors or capacitors, allowing DC to pass and blocking AC., Manufacturer: Ounfhtrttk
