Test conditions and notes13

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Output hiccups under no-load condition.
3. Please refer to “DRIVER METHODS OF LED MODULE”.
4. De-rating may be need under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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. Efficiency is measured at 500mA/50V output set by ETS database.
7. Standby power consumption is measured at 230VAC.
8. Flicker is measured at full load with LED modules.
9. 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)
10. 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. For XLC-S series: RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
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 70℃ or less.
12.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).

FAQ

Can I use the XLC-25-H-KNS to control LED downlights through a KNX building automation system?

Yes. The XLC-25-H-KNS is designed for KNX system integration and sets output current via a dip switch, allowing flexibility across different LED loads. With a 9–54V constant current range and 25W output, it suits LED downlights whose forward voltage string falls in that range.

Is the XLC-25-H-KNS suitable for residential KNX lighting with dimming requirements?

Yes. The driver supports dimming down to 0.5% minimum, which provides smooth control across the full dimming curve expected in KNX lighting scenarios. The current can be set between 300mA and 1050mA using the ETS database.

Can this driver be used in LED display or signage modules within a KNX-controlled environment?

Yes. The XLC-25-H-KNS operates as a constant current driver over a 9–54V range, making it usable for small LED arrays or signage modules in a KNX installation. The actual number of LEDs depends on each LED's forward voltage.

What is the difference between the XLC-25-H-KN and XLC-25-H-KNS?

Both models are 25W KNX-compatible LED drivers with 300mA output and a dip-switch current range of 300–1050mA. The XLC-25-H-KNS adds strain relief and has dimensions of 147.0 × 40.0 × 32.0 mm, whereas the XLC-25-H-KN omits strain relief and measures 107.0 × 40.0 × 32.0 mm.

What is the operating temperature range of the XLC-25-H-KNS?

The XLC-25-H-KNS is rated for operation from -25°C to +85°C, covering standard indoor commercial and residential environments.

How do I determine how many LEDs the XLC-25-H-KNS can drive?

The driver outputs constant current within a voltage range of 9–54V. The number of LEDs it can drive depends on the forward voltage of each LED in the string — you need to ensure the combined forward voltage of all LEDs falls between 9V and 54V at the selected current.
