jussming 20A Synchronous Buck CC/CV Module, Adjustable 6-40V to 1.2-35V DC-DC Converter, High-Efficiency LED Driver & Battery Charger (93g, 14x12x3cm)

["ALL-IN-ONE POWER SOLUTION:‌ Combines Constant Current (CC) and Constant Voltage (CV) modes in one compact module. Ideal for driving high-power LEDs, charging Li-ion/LiFePO4/Ni-MH batteries (4V-24V), and managing solar/wind energy systems with exceptional efficiency.","‌HIGH-CURRENT PERFORMANCE:‌ Delivers up to 20A output (15A continuous recommended). Built-in thermal protection alerts at 65°C – simply add a fan for sustained high-power operation. Ensures reliable performance under demanding conditions.","‌WIDE ADJUSTMENT RANGE:‌ Accepts 6-40V DC input and provides continuously adjustable 1.2-35V DC output (32V max for prolonged use). Independently adjustable current limit (0.2A-20A) offers precise control for diverse applications.","‌EFFICIENT & LOW DROPOUT:‌ Synchronous rectification design minimizes power loss, with a low dropout voltage of 3V. Maximizes energy utilization when input voltage is close to output, reducing heat generation.","‌EASY CALIBRATION & COMPACT DESIGN:‌ Two-step setup: adjust voltage with CV potentiometer, then fine-tune current with CC potentiometer. Lightweight (93g) and small (14x12x3cm) for easy integration into projects."]
