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.
