Description: This dual-output isolated AC-DC switching power supply board is designed to convert AC mains power into stable low-voltage DC power for electronic equipment. It integrates input fuse protection, EMI filtering, surge-current suppression, high-voltage rectification and filtering, PWM power control, optocoupler isolation, and output regulation circuits. The board provides 12V and 3.3V DC outputs to supply power to main control boards, sensors, communication interfaces, and other low-voltage electronic circuits. LJPCB provides one-stop PCB manufacturing and PCB assembly services, including PCB fabrication, component sourcing, SMT assembly, functional testing, and turnkey PCBA solutions.
