4A DC-DC Buck-Boost Adjustable Regulator Module with Display

The 4A DC DC Buck Boost Regulator Module is a vital and versatile component in the electronics industry. Thanks to its high precision and reliable performance, it is widely used in various projects, including adjustable power supplies and industrial control systems. This module, with its 0.5–30V 4A DC-DC Buck-Boost Converter capability, allows for a wide range of output voltage adjustment, providing exceptional flexibility for different applications.

The input voltage for the XY-SJVA-4X 5.5–30V DC-DC Buck-Boost Voltage and Current Regulator Module can range from 5.5 to 30V DC. When using a 5V input, both buck and boost functions remain operational, though voltage and current measurement accuracy may slightly decrease. If the input voltage drops below 4.7V, the undervoltage protection activates, safeguarding the module and sensitive components. This feature enhances system safety and reliability.

The module can provide a stable 3A output continuously, and with improved cooling, it can handle up to 4A. This makes the 4A DC-DC Buck-Boost Regulator Module ideal for projects requiring high current. Its output power under normal cooling conditions is 35W, which can reach up to 50W with enhanced ventilation.

Equipped with a high-resolution display (0.05V for voltage and 0.005A for current), the Output Voltage and Current Adjustment Module enables precise monitoring and control of the output, making it essential for applications like battery charging and electronics laboratories. The module achieves an energy conversion efficiency of approximately 88%, demonstrating its performance and energy optimization.

Another key feature is the soft start function, which prevents damage when connecting large loads. The module also includes reverse polarity input protection, output reverse current protection, and short-circuit protection, ensuring device safety and durability. These features make it suitable for demanding industrial environments.

The HW-140 DC-DC Buck-Boost Regulator Module, with its 180 kHz operating frequency, guarantees smooth, low-noise performance in sensitive circuits. It is widely used for voltage and current regulation in electronic devices, adjustable power supplies, and industrial automation systems. Additionally, the simultaneous display of output voltage and current allows for faster, more precise adjustments, optimizing overall performance.

Overall, this 0.5 30V 4A DC DC Buck-Boost Converter with advanced features and multiple protective functions is an excellent choice for electronics engineers and DIY enthusiasts. Its ability to provide high current and adjustable voltage makes it suitable for a wide range of industrial and laboratory applications. In summary, this 30V DC-DC Buck-Boost module delivers high performance, comprehensive protection, and precise control, making it a reliable solution for voltage and current regulation in various electronic circuits.
