The RS2809 DC Buck-Boost Converter Module is a highly versatile, programmable DC-DC power regulator that can step up (boost) or step down (buck) voltage depending on the input/output requirements. It features a wide input voltage range (5V–30V) and a continuously adjustable output (0.6V–30V) with both Constant Voltage (CV) and Constant Current (CC) modes, making it suitable for powering and charging a wide range of DC devices.
The module supports up to 35W power output and 4A current (with proper cooling). A built-in LCD display shows real-time voltage, current, and power, helping users monitor performance and protect connected devices. The converter uses a high-efficiency switching regulator with protection features like input reverse polarity, overcurrent, and thermal shutdown.
It is ideal for bench power supplies, LED drivers, battery charging (Li-ion, LiFePO4), test equipment, solar regulators, and more.
