- 6. Based on IEC 62386-101/102 DALI power on timing and interruption regulations,the set up time needs to test with a DALI controller which can support for DALI power on function,otherwise the set up time will be longer than 500ms.
- 7. Input over voltage only for XLG-320 I series,and I series without UL/CSA certificate.
- 8. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 9. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
- 11. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
- 12. Products sourced from the Americas regions may not have the CCC/PSE/BIS/KC logo. Please contact your MEAN WELL sales for more information.
- 13. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
- 14. The efficiency will drop 1% based on auxiliary power version with full load 3W condition.
- 15. H type:RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations； M/L type:RCM is on a voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1
- 16. To fulfill requirements of the latest ErP regulation for lighting fixture, this LED driver can only be used behind a switch without permanently connected to the mains.

FAQ
Can I use the XLG-320-M-DA2 to drive LED downlights in a large commercial space?
Yes. The XLG-320-M-DA2 delivers 310.8W at 2800mA constant current with a CC voltage range of 115–230V, making it well suited for powering series strings of high-power LED downlights in commercial installations. The DALI2 interface allows individual dimming control from a building automation system.
Is the XLG-320-M-DA2 suitable for outdoor LED signage cabinets?
Yes. The driver carries an IP67 waterproof rating, so it can be mounted inside outdoor signage enclosures exposed to rain and dust. Its operating temperature range of -40°C to +90°C also covers most outdoor climates.
Can the XLG-320-M-DA2 power an array of large-format LED modules in architectural lighting?
Yes. With 310.8W of output power and an adjustable current range of 1050–2800mA, this driver can support a series array of high-power LED modules within the 115–230V CC voltage range. The exact number of LEDs in the string depends on each LED's forward voltage.
Does the XLG-320-M-DA2 work with DALI2 dimming controllers?
Yes, the driver is designed specifically for DALI2 dimming systems. It supports a minimum dimming level of 8% and integrates directly with DALI2-compliant controllers for smooth, bus-addressed dimming.
How many LEDs can the XLG-320-M-DA2 drive in a series string?
The driver's constant current region spans 115–230V, so the number of LEDs in the string depends on the forward voltage of each individual LED. There is no fixed LED count — select LEDs whose combined forward voltages fall within that 115–230V range at your desired operating current.
Can the XLG-320-M-DA2 be installed in a sealed or wet-location enclosure?
Yes. The IP67 rating means the driver is protected against temporary immersion and continuous water ingress, making it appropriate for sealed enclosures or damp/wet-location installations. The -40°C to +90°C operating temperature range adds further flexibility for environmental extremes.
How does the XLG-320-M-DA2 compare to other 300W-class DALI2 drivers in the XLG series?
Within the 320W DALI2 tier, the XLG-320-H-DA2 outputs 312W at up to 65V/5600mA for lower-voltage, higher-current strings; the XLG-320-L-DA2 outputs 315W at up to 340V/1400mA for long series strings; and the XLG-320-M-DA2 outputs 310.8W at up to 180V/2800mA, occupying the mid-range voltage and current position. All three share the DALI2 interface and IP67 rating.
