Mean Well LED Switching Power Supply - 5VDC, 8A

This is a 40W single output switching power supply from Mean Well that has been specifically designed to be used with LED applications. This power supply is extremely reliable and able to output 5VDC at up to 8A. We’ve been testing this power supply for quite some time and can definitely attest to its durability with its fully encapsulated IP67 plastic casing, short circuit, overload, and over voltage protections.

The power supply includes wire pairs for the input (brown and blue) and output (red and black). Keep in mind that the input voltage does require an AC power cable to be connected that is not included with the power supply. This specific model is perfect when used with high power consumption LED projects and is cooled by free air convection and operates at a temperature of -30°C to +70°C. Mean Well has really outdone themselves with their power supplies, which are high quality and should last for quite some time without issue!

  • Output Voltage: 5VDC
  • Output Current Range: 0 -- 8A
  • Output Rated Power: 40W
  • Input Voltage Range: 90 -- 264VAC, 127 -- 370VDC
  • Protections: short circuit, overload, over voltage
  • Cooling by free air convection
  • 100% full load burn-in test

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

This thing is great.

Compact and easy to use. I mounted it inside an existing fluorescent light enclosure with some LED strips.
