Versatile Application: Perfect for a broad range of uses, this boost converter efficiently steps up DC voltage from 4.0-35V to 5-45V. It's ideal for powering electric equipment, digital products, and more, ensuring reliable performance for your devices. Convenient Design: Featuring easy-to-access screw terminals for quick wiring, along with a built-in heat sink, this boost converter facilitates enhanced heat dissipation and simple setup, making it user-friendly and efficient for all users. Instructions for use: 1. Connect the power supply (4-35V); the input indicator light turns on when the module is working properly. 2. Adjust the blue potentiometer knob: clockwise to increase voltage, counterclockwise to decrease voltage. Use a voltmeter for accurate measurement. 3. If the input and output voltages are the same, rotate the knob several times counterclockwise and then use it normally. Note: 1. The output voltage must be higher than the input voltage before it can be used. 2. The output current cannot exceed 5A. 3. The input voltage must not be less than 4V.
