Simplified and 12V 500W 40A Switching Power Converter for 110V AC to 12V DC Transformation with Cooling Fan and Power Adapters

The power converter comes equipped with a built-in cooling fan and temperature detector. The cooling fan will automatically start running when the internal temperature reaches 113°F (45°C), enabling more efficient and silent heat dissipation.

Prior to use, the 110V/220V switch must be set accordingly to avoid damaging the device. For use in the USA/Canada, please select the 110V setting, and for European regions, choose the 220V setting.

Comprehensive safety features are integrated, including safeguards against overvoltage, overcurrent, overheating, and short-circuits, providing ultimate protection for you and your connected devices.

The switching power supply converter supports a dual input voltage range of AC 110V-120V and 220V-240V. The output power range can be 12V, 1A-5A (12W-60W) or 12V, 10A-40A (120W-400W). The input voltage will automatically adjust to the specific SMPS model, while the output current primarily depends on the connected equipment. This dual-input voltage converter offers great flexibility and reliability, suitable for use in various power supply scenarios and regions.

Crafted with high-quality materials, the power converter features full copper nickel-plated terminals, ensuring excellent conductivity, high conversion efficiency, corrosion resistance, and aging resistance. The lightweight and portable design allows for convenient operation without limitations on time and space.

Strategically placed heat dissipation holes, a built-in cooling fan, and a dust filter work together to effectively prevent dust intrusion and promote efficient heat dissipation.

The included package comes with alligator clips and car cigarette lighter positive and negative cables, making the power converter suitable for a wide range of applications, such as powering LED lighting, CCTV camera security systems, communications equipment, household appliances, and other electronic devices.

Safety features like short-circuit, overvoltage, overload, overtemperature, overcurrent, and low voltage protection are integrated into the 12V switching power supply converter, ensuring reliable and secure operation.

We are committed to providing high-quality service, and if you have any questions or issues regarding the power converter, please do not hesitate to contact us, and we will strive to resolve the problem to the best of our abilities.
