6. Installation and Wiring
The power supply board is designed for easy integration. Follow these steps for proper installation:
- Mounting: Secure the power supply board using the mounting holes provided on its aluminum casing. Ensure it is mounted on a stable, non-conductive surface.
- Cooling: Due to potential heat generation under load, it is highly recommended to install the board on a radiator or ensure active cooling (e.g., a fan) to maintain optimal operating temperatures.
- Input Connection: Connect the AC input (170-265V) to the designated input terminals (typically marked 'L' and 'N'). Ensure correct polarity and secure connections.
- Output Connection: Connect your DC load to the output terminals (typically marked '+' and '-'). Observe correct polarity for your application.
- Verification: Double-check all connections before applying power to prevent damage to the power supply or connected devices.
Warning: Ensure power is disconnected before making any connections or adjustments to avoid electrical shock.
7. Operation
Once properly installed and wired, the power supply module operates automatically. Apply the specified AC input voltage, and the module will provide a stable DC output. The built-in protection mechanisms will activate in case of overload, short-circuit, or overheating, ensuring safe operation.

8. Maintenance
The power supply board requires minimal maintenance. Keep the unit clean and free from dust and debris. Periodically check connections for tightness and ensure adequate ventilation or cooling remains unobstructed. Do not attempt to repair the module yourself; refer to qualified service personnel if issues arise.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage | No input power; incorrect wiring; internal fault | Check input power source and connections; verify wiring polarity; if problem persists, discontinue use and seek professional assistance. |
| Output voltage unstable or low | Overload; poor connections; input voltage fluctuations | Reduce load; check and secure all connections; ensure stable input voltage. |
| Module gets excessively hot | Insufficient cooling; excessive load | Ensure proper ventilation or active cooling; reduce load to within specifications. |
| High-frequency squeaking sound | Interference with other connected devices (e.g., certain voltage regulators) at idle/no load. | This may be normal behavior with specific loads or at idle. If it's disruptive, try isolating the power supply or adding a minimal load. |

10. User Tips
- Cooling is Crucial: Under maximum load, the power supply board generates significant heat. Always ensure it is installed on a suitable heatsink or has active cooling (e.g., a fan) to prevent overheating and ensure longevity.
- Overcurrent Protection: The unit features overcurrent protection. If the load exceeds approximately 13 amperes (for the 12V model), the unit may enter a limit state and restore operation once the current decreases.
- Synchronous Rectification: The output utilizes synchronous rectification with MOSFETs, contributing to its efficiency.
- Idle Noise: Some users have reported a high-frequency squeak when the power supply is used with certain voltage regulators at idle (no load). This may be normal behavior for specific setups; consider adding a minimal load or isolating the power supply if it's an issue.
- Input Connector: While not included, consider sourcing an appropriate connector for the AC input side for easier and more secure wiring.
