QWORK® 5 Pack Buck Converter, LM2596S DC to Step Down Module 3.2-40V 1.25-35V 3A High Efficiency Voltage Regulator

PRECISION VOLTAGE REGULATION: Efficiently steps down DC 3.2-40V to a stable 1.25-35V output. Perfect for sensitive electronics requiring exact voltage control with up to 3A output current. STABLE LM2596S CHIPSET: Built with quality thickened circuit boards and inductors. Ensures superior heat dissipation and long-term stability for demanding industrial or hobbyist projects. VERSATILE DIY APPLICATIONS: A must-have component for robotics, telecommunications, and custom vehicle electronic modifications. EASY MANUAL ADJUSTMENT: Features a high-precision blue potentiometer for smooth tuning. Simply rotate the gold screw to reach your target voltage; clearly marked terminals ensure safe, quick installation. VALUE 5-PIECE PACK: Compact 43x21x14mm design fits easily into small enclosures. Includes five modules for multiple projects. Note: Input must be at least 1.5V higher than desired output.For output current below 2A, a heatsink is not required for extended periods. For output current greater than 2.5A (or output power greater than 10W), a heatsink should be added for prolonged operation.
