Frequently Asked Questions
Q: What is the input voltage range for this switching power supply module?
A: This AC-DC buck converter module accepts a universal AC input voltage of 85V to 240V, making it compatible with standard mains power supplies around the world — including North America (110–120V) and Europe/Asia (220–240V).
Q: What devices can I power with this 13.5V 1.5A power supply board?
A: This module is ideal for powering LED strips, LED drivers, small DC motors, microcontroller boards, relay modules, sensors, and other electronics that require a stable 13.5V DC supply at up to 1.5A (approximately 20W).
Q: Is this module safe to handle as a bare PCB?
A: Since this board connects directly to mains AC voltage, it should be handled by individuals with appropriate electronics knowledge. Always ensure the board is properly enclosed, insulated, and de-energized before handling. Following basic electrical safety precautions is strongly recommended.
Q: What is the difference between a switching power supply and a linear power supply?
A: A switching (buck) power supply converts AC to DC using high-frequency switching, which is significantly more energy-efficient and generates less heat compared to traditional linear regulators. This makes switching modules better suited for space-constrained or thermally sensitive applications.
