Matters needing attention
1. Before using the power supply, confirm that input and output voltage specifications match your equipment requirements.
2. Double-check input and output connections prior to powering on, to avoid possible equipment damage or power supply failure.
3. As the component side on the board is conductive, do not touch the bottom during testing. Always place the board on an insulating pad, clean paper, or other non-conductive material to prevent electrical shock or damage.
