AC Dimmable Power Supplies/LED Drivers

Looking for high power factor drivers? Check out our Universal+ Dimming LED Power Supplies, available in both 12 VDC and 24 VDC.

Dimmable LED drivers are used for full-range brightness control of white LED lighting products using AC dimming controls.

For use with 12-volt white LED lighting

For use with 24-volt white LED lighting

Dimmable power supplies, also called LED drivers, are a great option when you are replacing existing incandescent or fluorescent under-cabinet lighting or when you have an electrical outlet controlled by a wall switch. Simply wire the dimmable driver to the existing outlet wiring, and replace the on/off AC switch with an AC dimmer. In general, dimmable LED drivers require a hard-wire connection to your household circuit, the exception to this being wireless, plug-in “lamp dimmers.” Never use a low voltage DC dimmer/color controller on the same circuit as an AC dimmer.

Multiple LED driversLarge area lighting and dimming

Large lighting applications may require the use of multiple AC dimmable drivers/power supplies. For synchronized on/off and brightness control of LED lighting on multiple power supplies, connect a 120-volt AC dimmer to multiple Armacost Lighting Dimmable LED Drivers.

Choose the appropriate power/wattage output

Dimmable LED drivers are available in 20–120 watt models. The amount of power needed for your application is dependent on the watts required by your LED lighting. The watts required for each Armacost LED lighting product can be found in their associated installation guidelines. For RibbonFlex Pro LED tape lighting, the power or watts required depends on the brightness model as determined by LED density (number of LEDs per meter), the length of the lighting being installed, and the design configuration for your application. Read the installation guidelines for the LED light product you are using and choose a driver/power supply rated greater than your needs – you cannot overpower LED tape lighting.
