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-KN to drive LED downlights in a KNX smart home system?

Yes. The XLC-25-H-KN is specifically designed for KNX systems and allows the output current to be set via the ETS database. It operates as a constant current driver with a CC voltage range of 9–54V, making it suitable for LED downlights whose forward voltage string falls within that range.

Is the XLC-25-H-KN appropriate for use in a KNX-controlled office lighting installation?

Yes. With a minimum dimming level of 0.5% and a current range of 300–1050mA selectable via the ETS database, this driver supports the full dimming range expected in office lighting on a KNX bus. It accepts 100–305VAC input, covering both European and North American mains voltages.

Can I use the XLC-25-H-KN to power LED modules in small signage or display applications on a KNX network?

Yes. The 25W output and 9–54V constant current range make it usable for small LED signage or display arrays within a KNX-controlled network. The number of LED modules it can drive depends on the forward voltage of each module — verify that the string voltage falls within 9–54V.

Does the XLC-25-H-KN come with strain relief?

No. The XLC-25-H-KN does not include strain relief. If strain relief is required for your installation, the XLC-25-H-KNS is the same driver with strain relief included and the same 25W, 300mA output specifications.

What is the operating temperature range for the XLC-25-H-KN?

The XLC-25-H-KN operates from -25°C to +85°C. This covers most indoor commercial and residential environments.

How many LEDs can the XLC-25-H-KN drive at once?

The driver supports a CC voltage range of 9–54V at an output current settable from 300mA to 1050mA via the ETS database. The number of LEDs in the string depends on the forward voltage of each individual LED — no fixed count applies. Ensure the total string voltage stays within 9–54V.
