AC DC Switch Mode Power Control Circuit Board Assembly High Efficiency PCBA

This AC-DC power supply PCBA is a fully assembled switch-mode power control circuit board. It integrates complete EMI input filtering, a rectifier circuit, a PWM control chip, a safety protection circuit, and a power output unit. A slide switch controls power on and off, and the compact dual-section design supports low-power AC-DC conversion for consumer electronics. Ningbo MingXi supplies it through our PCB assembly services from China, with OEM and ODM customization.

Key Functions

• EMI input filtering: low electromagnetic interference from a mature, stable circuit design.
• Rectifier circuit and PWM control chip: switch-mode AC-DC conversion for low-power products.
• Safety protection: built-in short-circuit, over-current, and over-voltage protection.
• Power output unit: delivers the converted DC output.
• Slide switch: power on/off control on the board.
• Compact layout: size and function can be customized for OEM and ODM projects.
