Test conditions and notes14
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. De-rating may be need under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  3. 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uF & 47uF parallel capacitor.
  4. 4. Tolerance: includes set up tolerance, line regulation and load regulation.
  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.
  6. 6. Flicker is measured at full load with the light source provided by MEAN WELL.
  7. 7. To fulfill requirement of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
  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 de-rating of 3.5℃/1000m with fanless models and 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
  10. 10. 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.
  11. 11. For XLC-S series: RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations. For XLC(except -S) series: RCM is on a voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.

FAQ

Can the XLC-40-H-S drive LED downlights with the output current configured by dip switch?

Yes, the XLC-40-H-S uses a dip switch to set the output current within the 0.6–1.4A adjustment range. This allows the drive current to be matched to different LED downlight loads at commissioning time. Once set, the constant current output maintains stable current to the LED load across the full 9–54V CC operating range.

Is the XLC-40-H-S appropriate for powering LED modules in retail signage or channel letter applications?

The XLC-40-H-S can drive LED signage modules whose cumulative forward voltage falls in the 9–54V CC range and total consumption stays within 40W. The dip switch current selection lets installers tune the output at installation to match the specific LED module's rated drive current. The number of LEDs per string depends on each LED's forward voltage.

Can the XLC-40-H-S be used for flicker-sensitive applications such as studio or broadcast lighting?

The XLC-40-H-S is specified as flicker-free, making it suitable where camera-visible flicker must be avoided. It delivers 40W at 1050mA constant current across a 9–54V CC range, and its Class II design with PFC meets the electrical quality requirements common in professional lighting environments.

What is the benefit of the strain-relief fitting on the XLC-40-H-S compared to the XLC-40-H model?

The XLC-40-H-S adds a factory-fitted strain-relief cable fitting to the base XLC-40-H specification, mechanically securing the output cable at the housing. This reduces stress on the cable connection from tension or movement during and after installation. Both models share the same 40W, 1050mA, 9–54V constant current electrical specifications.

What LED voltage range is the XLC-40-H-S compatible with?

The XLC-40-H-S has a CC output voltage range of 9–54V and operates as a constant current driver. LED arrays with series forward voltages summing between 9V and 54V are compatible at the selected drive current. The exact number of LEDs per string is not fixed — it depends on the forward voltage of the specific LEDs being used.

Is the XLC-40-H-S rated for installation inside an enclosed luminaire in a warm environment?

Yes, the XLC-40-H-S is designed for built-in installation inside a luminaire or protective enclosure. It operates from -25°C to +90°C, accommodating elevated temperatures inside enclosed downlight housings. It does not carry an IP rating, so it should not be directly exposed to moisture.
