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

This is a 25W single output switching power supply from Mean Well that has been specifically designed to work with LED applications. This power supply is extremely reliable and able to output 5VDC at up to 5A. We’ve been testing this power supply for quite some time and can definitely attest to its durability with its IP42, fully isolated 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 compact for projects where you don't have a lot of space 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 -- 5A
  • Output Rated Power: 25W
  • Input Voltage Range: 90 -- 264VAC, 127 -- 370VDC
  • Protections: short circuit, overload, over voltage
  • Cooling by free air convection
  • 100% full load burn-in test

In this tutorial, we will be connecting a Mean Well LED switching power supply to an addressable LED strip controlled by an Arduino.

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.

  • Hello,

    Can I use this power supply with a MOSFET to dim (PWM) an LED strip?

    I'm not sure if this power supply requires a minimum load to regulate the output voltage properly.

    Thanks,

    Paul

    • Hi,

      I just noticed your comment after checking a spec on this product. For technical questions, it's usually better to contact our technical support team or post in the SFE forums. However, I can answer your question if you have not received an answer yet.

      The load should pull what it needs at and it should provide about 5V (+/- a small tolerance) from the power supply. I do feel that this might be overkill if your load is small. You'd probably be better off with a 5V wall adapter that outputs less current. Just make sure that the LED strip can be powered at 5V. Usually addressable LED strips are 5V while non-addressable LEDs are 12V. Non-addressable LEDs usually require a transistor (i.e. usually a N-Channel MOSFET) to control from a microcontroller or a timer.
