The following illustration shows the wiring and component configuration used to power four separate low voltage LED strip
light runs with the ability to dim the LED strips using a traditional wall-dimmer. This is a great setup for residential and
commercial installations where a clean, elegant and user-friendly LED strip light installation is desired.
LED strip lights operate on low voltage DC (e.g. 12V/24V), but wall-dimmers are installed in standard line voltage circuits which operate at AC 120 volts (North America / Japan) or 220-240 volts (elsewhere).
Two things must happen for the LED strip lights to work on the dimmer circuit. First, the voltage must be reduced and rectified from the AC line voltage to the lower DC voltage appropriate for the LED strip lights. Second, the dimming signal generated by the wall-dimmer must be interpreted and converted to the corresponding brightness setting on the low voltage DC side.
Waveform Lighting's dimmable power supply units offer the combined functionality of voltage transformation as well as dimming signal conversion and is an essential component in this setup.
This is a common setup for installations such as under-cabinet lighting applications where several short runs of LED strip may be interrupted by appliances or gaps such as stovetops or refrigerators. Note the max power supply capacity of 96 watts, which corresponds to approximately 16.4 ft (5 meters) of LED strip lights.
