Universal Regulated Switching Power Supply for LED, CCTV, and Computer Projects

The package included one 12V40A 480W Regulated Switching Power Supply, with the power cord not included. It is crucial to confirm the input and output voltage before use.

Firstly, you can choose the proper input voltage (110V/220V) using a black switch to avoid any potential damage. The left setting is for AC 110V, while the right is for AC 220V. For users in the USA/CA, the switch should be set to 110V.

Secondly, the 12V 40A output voltage can be regulated by ±15%, significantly expanding its application range. There is a yellow button on the right corner that can be used to fine-tune the output voltage by turning it clockwise.

It is important to note that the maximum use of power should not exceed 80% of the full loads, as this could shorten the power supply's lifespan. It is recommended to use this 12V 40A 480W power supply to power devices with a maximum draw of 32A 384W.

The unit does not come with installation instructions, wiring cables, an on/off switch, or screws. Therefore, professional installation by a qualified electrician is highly recommended.

There are several built-in safety features, including Over Voltage Protection, Overload Protection, Over Current Protection, Over Temperature Protection, and Short Circuit Protection. These features help to ensure the reliable and safe operation of the power supply.

If the LED power supply stops working, it is possible that the overcurrent protective switch has been triggered. In this case, it is important to unplug the AC cable and wait for approximately 10 minutes. After this, the power supply should automatically recover, and you can then reconnect it, allowing it to function properly again.

The power supply has a dual input voltage of AC 110V/220V and an output of DC 12V 40A max, with the output voltage being adjustable by ±15%. It is designed for indoor use only.

The power supply features two independent output channels, each capable of delivering up to 40A 480W, with a total combined output power of 40A 480W. It is compatible with devices that draw less than 40A, such as those with a DC 12V 1A~30A power requirement.

This high-quality power supply is widely used in various applications, including industrial automation, electronic equipment, LED displays, LED lighting, LED strips, CCTV cameras, security systems, computer projects, and home appliances.
