Frequently Asked Questions
Can I use the XLC-40-H-DA2SN to drive LED downlights in a DALI2 building automation system?
Yes, the XLC-40-H-DA2SN supports DALI2 dimming and integrates directly into DALI2-based building automation networks. It delivers 40W at a default 1050mA constant current and accepts DALI2 commands for individual or group dimming down to 0.1%, making it appropriate for commercial downlight installations that require addressable lighting control.
Is the XLC-40-H-DA2SN suitable for powering LED modules in illuminated signage or channel letter displays?
The XLC-40-H-DA2SN can drive LED signage modules as long as each module's forward voltage falls within the 9–54V CC output range and the total load stays within 40W. The number of series-connected LEDs per string depends on the forward voltage of each LED. Its DALI2 dimming also enables brightness scheduling for signage applications.
Can the XLC-40-H-DA2SN also be dimmed without a DALI controller, using a push button?
Yes, the XLC-40-H-DA2SN supports Push Dimming in addition to DALI2, so a simple push button can control brightness without a DALI bus or controller. This makes it flexible for both centrally managed DALI installations and simpler single-zone push-dim setups, with the same 0.1% minimum dimming level in both modes.
Can I adjust the output current of the XLC-40-H-DA2SN using NFC without opening the driver?
Yes, the XLC-40-H-DA2SN supports NFC current setting, allowing you to program the output current within the 0.6–1.4A adjustment range using a compatible NFC-enabled device. This lets you tune the drive current for different LED loads without physical access to internal dip switches or potentiometers.
Is the XLC-40-H-DA2SN rated for use inside an enclosed luminaire or fixture housing?
The XLC-40-H-DA2SN carries a Class II rating and is specified for built-in installation inside a luminaire or enclosure. It operates from -25°C to +90°C, accommodating the elevated ambient temperatures common in enclosed downlight housings. It does not carry an IP rating for direct moisture exposure.
What is the difference between the XLC-40-H-DA2SN and the XLC-40-H-DA2S?
The XLC-40-H-DA2SN and XLC-40-H-DA2S are both 40W, 1050mA DALI2 + Push Dimming drivers with strain-relief fittings. The key distinction is that the XLC-40-H-DA2SN adds NFC current setting, enabling wireless current adjustment in the 0.6–1.4A range, while the XLC-40-H-DA2S requires physical configuration for current changes. Both share identical input, output voltage range, and certifications.
What LED array voltage range is compatible with the XLC-40-H-DA2SN?
The XLC-40-H-DA2SN operates as a constant current driver with a CC voltage range of 9–54V. This covers a wide range of series LED arrays and downlight modules. The actual number of LEDs that can be driven in series depends on the forward voltage of each individual LED — do not assume a fixed LED count without knowing the specific LED's Vf.
