## Long description

Mean Well XLN-40-H-DA2 is an AC-DC constant power LED driver with an output voltage range of 9–54V and adjustable current from 0.6 to 1.4A. The unit supports DALI-2 control and NFC configuration, allowing addressable digital dimming and wireless parameter programming. Designed for professional lighting installations, this driver provides stable output suitable for linear and compact LED modules and enables simplified commissioning and remote operation where DALI-2 systems are used.
Advantages
The XLN-40-H-DA2 offers a wide output voltage window (9–54V) and a configurable current range (0.6–1.4A), delivering constant power to match various LED arrays without requiring multiple driver models. Built-in DALI-2 support enables standardized digital dimming and integration into modern lighting control networks. NFC configuration simplifies on-site setup and reduces commissioning time by allowing wireless programming of current, dimming curves and protection limits. The driver includes protections against overcurrent, overvoltage and short-circuit conditions to maintain system reliability.
Suitable for
Professional indoor LED fixtures and luminaires
DALI-2 controlled lighting systems in commercial buildings
Linear LED modules, LED strips and compact LED arrays within 9–54V
Projects requiring on-site configuration and flexible dimming
Key specifications
Brand: mean well
Model / MPN: XLN-40-H-DA2
Type: AC-DC constant power LED driver
Output voltage: 9–54V
Adjustable output current: 0.6–1.4A
Control protocol: DALI-2
Configuration: NFC programmable
How to use
Install the driver according to local electrical codes and the luminaire manufacturer's instructions. Connect the AC input to the supply mains with correct grounding and polarity where applicable. Wire the LED load ensuring the combined forward voltage falls within the 9–54V output range and set the desired current between 0.6 and 1.4A using NFC or DALI-2 commissioning tools. Use the DALI-2 interface for addressing, grouping and dimming control within compatible lighting management systems. Verify output settings and protective functions before finalizing installation.
Usage recommendations
For reliable operation, select LED modules whose forward voltage and current requirements match the driver’s output range and power capability. Use NFC to preconfigure drivers off-site when many units require identical settings. Integrate the driver into DALI-2 networks for centralized control and ensure routine inspection of connections and ventilation in enclosed luminaires to maintain temperature within specified limits.
