Performance and Safety
Equipped with short circuit, overload, over-voltage, and over-temperature protection to safeguard connected devices. Features a low noise EMI/RFI filter for stable output and full-load burn-in testing for quality assurance. The heavy-duty case minimizes temperature rise and improves durability. Consistent voltage is maintained during power-on and operation.

Important Usage and Safety Instructions
Please follow these guidelines carefully to ensure reliable and long-term performance of your 12V power supply.
1. Ventilation and Operating Conditions:Operate the unit in a dry, well-ventilated environment. Avoid sealed spaces or placing objects on top that could block airflow. Continuous heat buildup can reduce efficiency and shorten lifespan.
2. Voltage Configuration:The power supply is factory-set to 110V/115V for U.S. regions. If operating on 220V AC, move the selector switch to the correct position before powering on. Always verify input voltage to prevent internal component failure.
3. Load Management:For optimal efficiency, operate the device between 70–80% of its rated current. Overloading or prolonged use at full capacity may cause overheating or premature aging of internal parts.
4. Wiring and Grounding:Confirm that all terminals are securely connected and polarity is correct before applying power. Use appropriate cable thickness for your load. Proper grounding is required for electrical safety and noise suppression.
5. Maintenance and Inspection:Inspect the unit periodically. Clean vents with compressed air or a soft brush depending on the dust level in your environment—typically every 2–3 months. Check terminals for looseness or corrosion to maintain stable contact.
6. Environmental Cautions:Use indoors only, away from moisture, condensation, or high humidity areas. Do not install near water sources or in corrosive environments. In areas with unstable mains power, consider using a UPS or voltage stabilizer.
7. Radio Frequency Considerations:This unit includes an EMI/RFI filter to minimize interference. However, it is not intended for direct use with sensitive radio transmitters or amateur radio equipment where noise isolation is critical.
8. Safety Warnings:High voltage exists inside the housing—do not remove the cover or attempt to repair internally. If unusual sounds, heat, or odor occur, disconnect power immediately. Installation should be performed by a qualified electrician. The package does not include cables, switches, or screws; please prepare them as needed.
