DC-DC Buck Converter Module 6-40V to 1.2-36V Adjustable CC CV 300W 20A Power Supply Step Down Module with Screw Terminal YTACSFAGD-300W
⚡ 300W 20A High Power with Wide 6-40V Input to 1.2-36V Output Need to power high-demand devices from a 12V or 24V battery? This buck converter delivers up to 300W continuous (20A max, 15A recommended for long life). Step down 6-40V DC to any adjustable 1.2-36V output. Efficiency reaches 96% at 24V to 12V 20A, minimizing heat and energy waste. 🔧 Independent CC/CV Dual-Mode Adjustment via Two Potentiometers Tired of modules that can’t handle constant current for LED or battery charging? Separate potentiometers let you set output voltage (CV mode) and current limit (CC mode) independently. Perfect for LED drivers, lithium battery chargers, and motor controllers. Automatically switches between constant voltage and constant current regulation for safe operation. <50mV with Dual Heatsink for Stable Power about noisy power causing flickering or equipment damage? Input and output high‑frequency low‑ESR electrolytic capacitors deliver ≤50mV ripple – clean, stable power for sensitive electronics. Dual aluminum heatsink keeps components cool even at 20A load. Reduce power if input‑output voltage difference is large to maintain safe temperature. 🔌 30A Screw Terminals + 75V/80A Dual MOS Tube Design Hate soldering heavy gauge wires on power modules? Large 30A rated screw terminals accept up to 12AWG wire – just strip and tighten. 75V/80A dual MOS tube design handles high current surges smoothly, ensuring stable output and long‑term reliability. Compact size 60×53×27mm fits easily into enclosures. 💡 Universal DIY & Industrial Applications One module powers countless projects: LED arrays, high‑power LED drivers, lithium battery chargers (4V‑24V), solar panel regulators, wind turbines, CNC machines, 3D printers, telecom equipment, and motor controllers. Built‑in self‑recovery short‑circuit protection adds an extra safety layer for your valuable equipment.
