ZK-SJVA-4X Buck Boost Converter Module CV CC 4A 35W

The ZK-SJVA-4X Buck Boost Converter Module is a highly efficient, adjustable DC-DC step-up and step-down power supply designed for precision power regulation. Featuring a clear LCD digital display, this module functions as an integrated voltmeter, ammeter, and power meter, allowing you to monitor input/output voltage, current, and power in real-time. It is equipped with dual multi-turn potentiometers for precise Constant Voltage (CV) and Constant Current (CC) adjustments, making it an excellent choice for laboratory power setups, DIY projects, and high-power LED driving.

This versatile module is highly compatible with various power sources and microcontrollers, making it a staple for engineering students, makers, and hardware developers in India. It is widely used in solar power regulation, battery charging applications (including Lithium-Ion, LiFePO4, and Lead-Acid batteries), and as a stable driver for robotics and IoT projects. With built-in safety features like input reverse polarity protection and output anti-backflow protection, it ensures safe and reliable operation even during battery charging tasks.

Features:

• Automatic Buck-Boost Operation: Seamlessly steps voltage up or down to maintain a stable output regardless of input fluctuations.
• Integrated LCD Display: Displays real-time input/output voltage (V), output current (A), and output power (W) with high resolution.
• Adjustable CV and CC Limits: Dual high-precision potentiometers allow fine-tuning of voltage and current limits.
• Tactile Control Buttons: Onboard buttons allow easy toggling between input/output voltage displays and turning the output ON/OFF.
• Comprehensive Protection: Features input reverse connection protection, output anti-backflow protection, and short-circuit protection.
• Efficient Thermal Management: Equipped with a pre-installed aluminum heatsink to ensure stable performance under continuous load.
