Test conditions and notes17
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Please refer to "DRIVING METHODS OF LED MODULE".
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  5. 5. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time. Especially when the temperature inside driver is very high, it will lead to a longer set up time.
  6. 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. 7. Input over voltage only for XLG-240 I series,and I series without UL/CSA certificate.
  8. 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. 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. 10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  11. 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. 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. 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. 14. The efficiency will drop 1% based on auxiliary power version with full load 3W condition.
  15. 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. 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.
  17. 17. This series need to consider build in using to comply with Type HL application.

FAQ

Can the XLG-240-H-DA2 power high-bay LED fixtures in an industrial facility with DALI controls?

Yes. At 239.6W and up to 4900mA constant current (27–56V range), this driver can supply high-power LED high-bay modules. The DALI2 interface integrates with industrial building automation systems for occupancy-based or scheduled dimming down to 8%.

Is the XLG-240-H-DA2 suitable for stadium or sports lighting arrays requiring intelligent dimming?

Yes. The 239.6W output with adjustable current from 2400–6660mA and DALI2 dimming supports high-lumen LED arrays typical in sports and outdoor venue lighting. The IP67 waterproof rating accommodates outdoor luminaire enclosures.

Can I use this driver for large LED downlight arrays in a shopping centre with a DALI BMS?

Yes. The DALI2 protocol allows direct integration with building management systems for zone-level dimming control. The driver's 239.6W capacity with constant current in the 27–56V range supports clusters of high-power LED downlight modules in retail environments.

What is the current adjustment range of the XLG-240-H-DA2?

The output current is adjustable from 2400mA to 6660mA, with 4900mA as the nominal rating. The DALI2 minimum dimming level is 8% of the configured output.

Can the XLG-240-H-DA2 be used in cold storage or outdoor environments?

Yes. The driver is rated IP67 waterproof and operates from –40°C to +90°C, making it suitable for cold storage facilities, outdoor luminaire housings, and other harsh environments with wide temperature swings.

How many LEDs can the XLG-240-H-DA2 drive in series?

The constant current output region is 27–56V. The number of LEDs depends on each LED's individual forward voltage — no fixed count applies. Confirm the total series string forward voltage is within 27–56V at the configured drive current.

How does the XLG-240-H-DA2 compare to the XLG-200-H-DA2 and XLG-150-H-DA2?

The XLG-150-H-DA2 is rated 150W at up to 2800mA; the XLG-200-H-DA2 is 200W at up to 3500mA; the XLG-240-H-DA2 is 239.6W at up to 4900mA. All share the DALI2 interface, IP67 rating, and the same 27–56V CC voltage region. Select based on the total wattage and maximum drive current required by the LED array.
