12V 40A Power Supply Adapter for LED, 3D Printer, Car Stereo, CCTV Camera, Diesel Heater

This AC to DC universal power supply transformer converts 110V/220V AC input to a stable 12V DC output. The adjustable output range of 10.8V to 13.2V (±10%) greatly expands its application possibilities. With a maximum power rating of 40A and 480 watts, this power supply is capable of powering a wide variety of 12V devices.

When selecting a power supply, it is recommended to choose one that is at least 20% larger than your device's rated power to ensure safety. This AC to DC converter features three output channels, allowing you to power multiple devices simultaneously.

Weighing 1.65 lbs and measuring 8.46 x 4.52 x 1.96 inches, this power supply is compact and easy to handle. The metal construction with numerous ventilation holes ensures effective heat dissipation, maintaining the stability of the converter. Additionally, a built-in cooling fan runs continuously to protect the unit from overheating, with minimal noise.

For user convenience, this power supply features a switchable dual input voltage, allowing it to be used with both 110V and 220V AC power sources. The factory setting is 110V for US customers, but the voltage switch on the side can be adjusted to 230V (220V) if needed.

Safety is a top priority with this AC to DC converter. It has undergone 100% full-load burn-in testing, ensuring reliable performance. Smart chip technology provides automatic protection against overload, overvoltage, and short circuits, safeguarding your connected electronic devices. The power supply also features low output ripple and an integrated EMI filter, ensuring clean and stable power delivery.

This power supply is ideal for powering a wide range of 12V devices, such as LED strip lights, 3D printers, diesel heaters, and ham radios, among others. It automatically adjusts the output current to match the load, providing up to 40A (480 watts) of power. However, it is important to ensure that your device's voltage and current requirements are compatible with the 12V and 40A maximum specifications of this power supply, and to avoid overloading the unit.

In summary, this versatile AC to DC converter offers a stable 12V DC output with an adjustable range, ample power capacity, and robust safety features. Its efficient heat dissipation, switchable voltage input, and multiple output channels make it a reliable choice for powering a variety of 12V electronic devices.
