Frequently Asked Questions
Can I program the output current on the XLC-40-H-DA2N after the luminaire is installed?
Yes. The -N suffix indicates NFC current setting, allowing output current to be adjusted between 0.6A and 1.4A wirelessly through the luminaire housing using a compatible NFC programmer. This eliminates the need to access the dip switch once the fixture is in place.
Is the XLC-40-H-DA2N suitable for DALI2-controlled LED downlights in smart building projects?
Yes. It supports DALI2 and push dimming with a minimum dimming level of 0.1%, and NFC current setting simplifies post-installation commissioning. The 40W, 1050mA constant current output with flicker-free operation is appropriate for recessed or built-in commercial downlights.
Can I use the XLC-40-H-DA2N for LED modules in retail track or accent lighting with a DALI2 controller?
Yes. DALI2 support enables individual addressing and smooth dimming to 0.1%, which is useful in retail environments requiring precise accent-light level control. The built-in form factor requires mounting inside the luminaire enclosure.
How does the XLC-40-H-DA2N differ from the XLC-40-H-DA2 in current configuration?
Both models share the same 40W output, 1050mA nominal current, DALI2 dimming, and 0.6–1.4A adjustment range. The XLC-40-H-DA2 uses a dip switch for current setting, while the XLC-40-H-DA2N uses NFC. Choose -DA2N when the driver will be sealed inside a luminaire after installation.
What CC voltage range should my LED string meet for the XLC-40-H-DA2N?
The constant current output operates between 9V and 54V. LED strings must be sized so their total forward voltage at the selected drive current falls within this range. The number of series LEDs varies by LED type and its forward voltage at the operating current.
What is the operating temperature range of the XLC-40-H-DA2N and is it suitable for harsh indoor environments?
The driver is rated from -25°C to +90°C and carries CB, CCC, CE, EAC, ENEC, and c_selv certifications. It is specified for built-in use, so it must be housed in a suitable enclosure. For installations in high-ambient environments, ensure the luminaire enclosure provides adequate thermal dissipation.
