LED Controllers - APT-DW
ARKALUMEN APT-DW

Key Product Features

  • Enables Dim-to-Warm feature in constant current drivers

  • No auxiliary power required

  • Independent of dim method used

  • No perceivable flicker

  • Logarithmic, linear or customized CCT curves

Ultra-smooth Dim-to-Warm

APT-DW controllers are drop-in ready with simple wiring and ultra-smooth software enabled CCT shift during dimming. The patented controller measures the input current and shifts the current to the warmer channel as the input current is reduced.

FAQ

If I reduce the maximum current supplied to the APT-DW, how will the controller reset to this new limit for the full cool white level?2021-09-14T19:10:24+00:00
If you want your setup to operate at a lower maximum current than previously used, you can reset the APT-DW by applying the reset sequence to as is described in the data sheet
What kind of dimmer can we use with the APT-DW?2021-09-01T20:01:12+00:00

Whichever dimmer works with your driver. As long as the APT-DW is receiving a current, it detects the level of the current and adjusts the color based on the current level relative to the maximum current detected.

What control inputs are needed for the APT-DW?2021-09-01T20:01:52+00:00

The APT-DW does not need any control input other than the output of a dimmable constant current driver. It will use the change in current to automatically dim to the warmer LED colour.

Can the APT-DW be configured with the programmer to change the dim curve from the factory settings?2021-09-14T19:11:39+00:00
No, the APT-DW cannot be set using the APT Programmer.  It can only be set to a different dim profile (linear, logarithmic, or custom) by Arkalumen.  For applications requiring custom dim profiles to be changed after receiving the controllers from the factory, please see the APT-CC family of controllers.
