• High Efficiency: Conversion efficiency greater than 90%, minimizing energy loss.
• Dual and Four Channel Options: Available in dual-channel or four-channel configurations to power multiple devices.
• Reverse Polarity Protection (Dual-channel only): Safeguards against incorrect power connection.
• Compact Design: Dual-channel size: 60x60x12mm; Four-channel size: 100x68x12.5mm.
• Wide Temperature Range: Operational range from -25°C to +85°C, suitable for various environments.

Applications:

• Embedded Systems: Ideal for powering embedded development projects requiring multiple voltage rails.
• Robotics: Suitable for providing power to various subsystems in robotics applications.
• Power Supply for Sensors: Powers sensors, microcontrollers, and other electronic devices in scientific and industrial applications.
• Battery Charging Systems: Can be used in charging circuits requiring precise and adjustable voltage regulation.

Notes:

• The potentiometer adjusts the output voltage by turning clockwise to increase and counterclockwise to decrease the voltage.
• Since the potentiometer is a multi-turn precision potentiometer, it is recommended to turn it counterclockwise several times during the first use; otherwise, the adjustment effect will not be noticeable, and the output voltage may not change!
• The module is a step-down power supply, so the input voltage must be higher than the output voltage by at least 1.2V!
• The maximum output current per channel is 5A. It is recommended to keep the continuous current around 3A or add auxiliary heat dissipation measures.
