Electrician’s Guide to using the wall mount 12V 5A power supply with LED strips

Overview

This is a guide aimed at people who have experience working with mains electricity ‎and are aware of the safety precautions that must be taken when working with high ‎voltage electricity. It describes how to use the wall mount power supply to power ‎up to 10M of LED strips.

DO NOT ATTEMPT TO WIRE ANYTHING INTO THE ‎MAINS IF YOU ARE NOT QUALIFIED – SERIOUS INJURY MAY OCCUR.‎

You will need:‎

  • A wall mount PSU
  • Some LED Strips, Red, Green, Blue, Yellow, or White
  • A two-way terminal block (recommended) or a 5A 2.1mm DC socket.‎

Step 1‎

Wire_1

Identify the (brown) live and (blue) neutral wires on the AC side of the terminal. ‎These can be connected directly to a light fitting or into a plug if you prefer.‎

Step 2‎

Plug_2

You can connect the plug on the DC end into a 2.1mm 5A rated DC socket, as ‎these are far more expensive than the low current version, we recommend cutting ‎the 2.1mm plug off and running the two wires into a 2-way terminal block.‎

Step 3‎

Polar_3‎ ‎

Connect the positive and negative terminals on your terminal block to the ‎corresponding positive and negative pads on the LED strip. If you are using a full ‎strip then wires will already be attached to one end so you can wire these straight ‎into your terminal, noting the polarity indicators where the wires enter the LED strip. ‎The pads are labelled with + and – signs as can be seen in the image above.‎

Connecting LED strips in parallel

If you wish to use multiple LED strips exceeding a total length of 5M you must ‎connect them to your power supply in parallel as shown in the diagram below.‎

Notes

  • Cut lines are marked every 5cm along the LED strips, if you wish to shorten ‎a strip make sure you cut down the line and don’t damage the copper pads.
  • If you are connecting lengths of LED strips in series do not exceed 5m.
  • You can power a maximum of up to 12m of single colour LED strips from a ‎single 5A PSU if they are run in parallel.‎
