XH-M299 AC-DC Switching Power Supply Module

The XH-M299 is a compact power supply module that converts high-voltage AC (110–220V) into low-voltage DC output (5V and 12V). It is commonly used to safely power electronic circuits and microcontroller projects directly from mains electricity.

⚡ Key Features

• AC to DC Conversion:
  Converts 110V–220V AC into stable DC power
• Dual Output Voltages:
  • 5V DC (for microcontrollers, sensors)
  • 12V DC (for relays, motors, etc.)
• Output Current:
  • 5V: up to 100mA
  • 12V: up to 500mA
• Isolated Design:
  Provides electrical isolation for safer operation and reduced interference
• Compact Size:
  Approx. 35 × 25 × 15 mm – small and easy to install

🔌 How It Works

👉 You connect AC mains (L & N) to the input side.
👉 The module converts it into low-voltage DC outputs (5V / 12V).
👉 You can power your circuits directly from these outputs.

🧰 Applications

• Arduino & microcontroller projects
• DIY electronics
• Smart home devices
• Powering sensors, relays, and small modules

⚠️ Important Notes

• Works with high voltage (AC mains) — handle carefully
• Not suitable for high-power devices (limited current output)
• Ensure proper insulation when installing

💡 Simple Explanation

👉 It works like a mini power adapter on a circuit board —
you give it wall electricity, and it gives you safe low-voltage power for electronics.
