Frequently Asked Questions
Can the XLC-40-H-DA2 be controlled by a DALI2 lighting control system?
Yes. The XLC-40-H-DA2 supports DALI2 dimming along with push dimming as a secondary input. DALI2 compatibility enables integration with addressable digital lighting control systems for zone-based or individual luminaire control in commercial buildings.
Is the XLC-40-H-DA2 suitable for office downlights managed by a building management system?
Yes. DALI2 support allows the driver to receive dimming commands from a BMS or DALI2 controller, with dimming down to 0.1% minimum. The 40W, 1050mA constant current output is appropriate for single or multiple LED downlight modules wired in series within the 9–54V CC range.
Can I use the XLC-40-H-DA2 in museum or gallery LED accent lighting with precise dimming control?
Yes. The 0.1% minimum dimming level and flicker-free operation make it suitable for applications requiring accurate, smooth dimming to very low light levels. DALI2 allows individual luminaire addressing for scene-based and circadian lighting programs.
How does push dimming on the XLC-40-H-DA2 work alongside DALI2?
Push dimming provides a simple button-operated fallback for manual dim level adjustment when a DALI2 controller is not present. Both dimming inputs are available simultaneously, and DALI2 takes priority when a bus signal is present. This makes commissioning and standalone operation straightforward.
What LED arrays are compatible with the XLC-40-H-DA2's constant current output?
The CC output voltage range is 9–54V at 1050mA. LED strings whose combined forward voltage falls within this range are compatible. The actual number of LEDs in the string is determined by each LED's forward voltage — no fixed LED count applies.
How does the XLC-40-H-DA2 differ from the XLC-40-H-B on dimming protocol?
The XLC-40-H-B uses 3-in-1 analog dimming (0–10V, PWM, resistance), which suits most standard dimmers. The XLC-40-H-DA2 adds DALI2 and push dimming, enabling addressable digital control and 0.1% minimum dimming depth. Both share the same 40W, 1050mA output and dip-switch current setting.
