The internal 36V switch is capable ofĭriving up to eight LEDs in series with 20mA of LED The LED voltage, greatly simplifying the battery/adapter LED current even when the input voltage is higher than Its unique internal current source accurately regulates Regardless of differences in their forward voltage drops. The LT1932 uses a constant-current step-up architecture that directly regulates the LED currentĪnd guarantees a constant light intensity in each LED, Series should be used to ensure the same illumination Than voltage, a constant-current source driving LEDs in Since LED brightness is proportional to current rather White LEDs, matching the brightness becomes a majorĭesign consideration for multiple LED applications.

View Universal Dimming LED Drivers PDF Data Sheet 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. 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.

The watts required for each Armacost LED lighting product can be found in their associated installation guidelines. The amount of power needed for your application is dependent on the watts required by your LED lighting. Choose the appropriate power/wattage outputĭimmable LED drivers are available in 20–120 watt models. 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. Large lighting applications may require the use of multiple AC dimmable drivers/power supplies. Typical wiring when using a dimmable driver 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. Simply wire the dimmable driver to the existing outlet wiring, and replace the on/off AC switch with an AC dimmer.
