Mean Well XLC-25-H-DA2SN LED Driver 25W 700mA 9~54V Constant Power, DALI2 + Push Dimming with Strain-relief, NFC Current Setting

Q: Can I use the XLC-25-H-DA2SN to drive LEDs in a DALI2 commercial lighting system?

Yes. The XLC-25-H-DA2SN supports both DALI2 and push dimming, making it compatible with DALI2 bus controllers used in commercial lighting systems. It delivers up to 25W at a constant current output of 700mA across a CC voltage range of 9–54V, suitable for LED downlights and small LED arrays that fall within that range.

Q: Is the XLC-25-H-DA2SN suitable for LED signage modules that require precise dimming control?

Yes. The driver supports dimming down to 0.1%, which makes it suitable for signage applications that need smooth low-end dimming. The NFC current setting feature also allows the output current to be adjusted between 0.3A and 1.05A without physical access to the driver.

Q: Can I use this driver for LED downlights in a retrofit project that requires flicker-free operation?

Yes. The XLC-25-H-DA2SN is designed for flicker-free operation, which is important for commercial downlight retrofits where flicker can be a code or occupant comfort concern. With 25W output and a 9–54V constant current range, it suits a range of LED downlight modules — the number of LEDs that can be driven depends on the forward voltage of each LED.

Q: Does the XLC-25-H-DA2SN work with NFC programming tools for current adjustment in the field?

Yes. The driver includes NFC current setting, allowing the output current to be configured between 0.3A and 1.05A using a compatible NFC device. This is useful when the luminaire is already installed and physical adjustment is impractical.

Q: What is the operating temperature range of the XLC-25-H-DA2SN, and is it suitable for enclosed fixtures?

The XLC-25-H-DA2SN operates from -25°C to +90°C. It is a Class II driver rated for built-in (enclosed fixture) use, making it appropriate for recessed downlights and other enclosed luminaire housings where ambient temperatures can be elevated.

Q: How many LEDs can the XLC-25-H-DA2SN drive, and what voltage range is supported?

The driver operates as a constant current source with a CC voltage range of 9–54V at 700mA. The number of LEDs it can drive depends on the forward voltage of each individual LED — there is no fixed LED count. Ensure the total forward voltage of your LED string falls within 9–54V at the chosen current level.

Q: What distinguishes the DALI2 variants in the XLC-25-H series from other dimming variants?

Within the XLC-25-H family, the DA2 variants (XLC-25-H-DA2, DA2N, DA2S, DA2SN) add DALI2 bus dimming plus push dimming control, while the B variants add 0–10V dimming, the MA/MAS variants add Matter wireless dimming, and the KN/KNS variants are designed for KNX systems. The base 25W/700mA output rating is the same across all 60V constant current variants.
