Overview
The 300W 20A Buck Converter is a high-current powerhouse designed for demanding electrical loads. It features Constant Voltage (CV) and Constant Current (CC) adjustment, making it not just a regulator, but a full-blown battery charger and LED driver. Whether you are stepping down a 24V truck battery to 12V or driving high-wattage COB LEDs, this module remains stable and cool thanks to its massive dedicated aluminum heatsinks.
Key Features
Synchronous Rectification: Dramatically reduces heat and increases efficiency (up to 96%).
Dual Adjustment Knobs: Dedicated potentiometers for both Voltage and Current limiting.
Massive Current Support: Handles up to 20A (peak), allowing you to power heavy-duty DC motors or large LED strips.
Low Ripple Output: Includes high-frequency, low-resistance electrolytic capacitors for clean power delivery.
Short Circuit Protection: Features self-recovery protection (Note: Do not short circuit for extended periods at max current).
