How to wire a dimmable power supply for Under Cabinet Lighting14

Intro

In this post we will show how to wire a dimmable power supply for Under Cabinet Lighting.
The LED DC Drivers or Magnetic Transformers are used for dimming the LED Under Cabinet Lights.
For best dimming results you should use a Magnetic Low Voltage Dimmer.


Materials List

- 2 pcs 3/8 in. Flexible Metal Conduit (FMC) Combination Clamp Connectors
- 5 pcs Twister Wire Connectors
- 1 pcs 3 Prong Power Cord
- 1 pcs Power Supply
- Screwdriver
- Wire Stripper


Step 1

Take out the 1/2" knockout from each side and insert the Clamp Connector.


Step 2

Insert the 3 Prong Power Cord through the Clamp Connector and secure it properly using the screwdriver.


Step 3

Find the Wiring Diagram. In this case the Wiring Diagram is inside the cover plate.
As you can see in picture the 120V line will be the black wire and the neutral will be the white wire.
On the other side we will have the 12V low voltage and the Red wire will go to the positive wire (+) and the Purple will go to the negative (-) wire of Under Cabinet Lighting.


Step 4

Strip the white, black and green wires about 1/2 inch and twist white with white, black with black and green with green.
Twist properly the Wire Connectors.


Step 5

We will move now to the left side where we will connect the low voltage wire coming from the LED Under Cabinet Lights.
Insert the low voltage wire through the Clamp Connector and secure it properly using the screwdriver.


Step 6

Strip the red, purple and and the wires coming from the LED Under Cabinet Lights about 1/2 inch.
For our Super Bright Under Cabinet Lights all the time the positive wire is the wire with white line on it. In this case we will twist the Red wire from power supply with the wire with white line and the Purple wire from power supply with the other wire coming from the LED Under Cabinet Light or straight from the under cabinets.
Twist properly the Wire Connectors.


Last step

Put all wires nice inside the Power Supply and the cover up.
Plug it in.


This is how your Under Cabinet Lighting should look like
