Test conditions and notes14

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be need under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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. Tolerance: includes set up tolerance, line regulation and load regulation.
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. Flicker is measured at full load with the light source provided by MEAN WELL.
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. 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 de-rating of 3.5℃/1000m with fanless models and 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
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. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.

What output does the XLN-40-H-DA2 provide?

This model is rated for 40W output and 1050mA default current. The constant current region is 9~54V, with an open circuit voltage of 60V. The current is adjustable from 0.6A to 1.4A via NFC.

Does the XLN-40-H-DA2 support DALI dimming?

Yes. The XLN-40-H-DA2 includes DALI-2 dimming support and Push dimming, complying with IEC62386-101, 102, and 207. It also supports 3-in-1 dimming with dim-to-off functionality.

Can the output current be adjusted on this model?

Yes. The XLN-40-H-DA2 supports NFC current setting for selectable output stages on the H-type model. The current can be adjusted from 0.6A to 1.4A. This is useful when the same driver family needs to support different LED load requirements within the stated model capabilities.

Is the XLN-40-H-DA2 suitable for damp or outdoor-rated lighting environments?

Yes. The XLN-40-H-DA2 has a fully encapsulated IP67 housing, which provides strong protection against dust and water ingress. It is also rated for operation from -25°C to 90°C case temperature, based on the provided temperature range.

What makes the XLN-40-H-DA2 different from a basic non-dimming LED driver?

This model includes DALI-2 and Push dimming support, NFC current setting, and a minimum dimming level of 0.1% according to the product description. It also has flicker-free operation, PFC design, IP67 encapsulation, and standby power consumption below 0.5W.

What warranty does the XLN-40-H-DA2 include?

The XLN-40-H-DA2 includes a 5-year warranty. That warranty period matches the product data and is typical buyer-relevant information for commercial LED driver selection.

Is the XLN-40-H-DA2 appropriate for emergency lighting applications?

The product description states that this model meets emergency lighting function application requirements. Buyers considering this driver for emergency lighting should evaluate it against the rest of the system requirements and applicable project standards.
