Dimmers have fast become a vital part of many lighting applications and installations. Dimmers allow you to set the level of light and save energy on the output and when teamed with an LED light source, this energy saving can be quite substantial.

Phase-cut dimmers are the most common dimming control and are often referred to as TRIAC dimmers. Creating the ideal configuration of LED lamps with the TRIAC dimmer has, in the past, been a challenge, but now TRIAC dimming LED drivers has made this much simpler. So how to connect a triac dimmable power supply with a dimmer?

A typical dimmable driver installation is shown above. Please review the materials provided with your dimmer switch and dimmable driver to make sure it matches.

A dimmable driver installs almost identically to a non dimmable power supply. On the DC (output) side, you’ll connect the positive and negative wires to the LED Light Strip (or other low voltage lighting product). On the AC (input) side, you can choose live wire or netural wire to connect dimmer. The live wire or netual wire from your household power source will connect to the input of the dimmer switch - and the output of the dimmer switch will then connect to the live wire or netural of the dimmable driver.
