Test conditions and notes15

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
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. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. 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.
7. No load/standby power consumption is specified for 230VAC input.
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. 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.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
11. 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).
12. 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
13. BIS IS15885(for 12/12A/12B/12DA/24/24A/24B/24DA/36/36A/36B/42A/42B/48/48A/48B/54A/54B).
14. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
15. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-200-42DA be integrated into a DALI building automation system?

Yes. The 'DA' suffix indicates a native DALI (Digital Addressable Lighting Interface) input, allowing the driver to receive individual dimming and on/off commands over a two-wire DALI bus. This is the standard protocol for intelligent lighting control in commercial office, retail, and institutional building automation systems.

Is the ELG-200-42DA suitable for outdoor architectural LED lighting with DALI control?

Yes. The IP67 waterproof rating protects against temporary immersion, and the -40°C to +90°C case temperature range covers outdoor conditions in most climates. Combined with the DALI interface, it enables individually addressed dimming of outdoor façade or landscape LED zones from a building management system.

How much 42V LED strip load can the ELG-200-42DA handle?

The driver outputs 199.9W at 42V. For a 10W/m strip, that supports up to roughly 19.9 m (199.9 ÷ 10); for a 15W/m strip, approximately 13.3 m (199.9 ÷ 15). Apply a 20% derating for thermal safety, reducing those practical limits to about 16 m and 10.6 m respectively. Check your strip's rated power per meter for an accurate calculation.

Can I use the ELG-200-42DA to control zone brightness individually in a large office lighting installation?

Yes. DALI allows up to 64 individually addressable devices on a single bus, so multiple ELG-200-42DA units can be assigned separate DALI addresses and dimmed independently. This is ideal for open-plan offices where different zones require different illumination levels under a single controller.

Is the ELG-200-42DA appropriate for powering LED strips in a hotel corridor or public space with automated lighting scenes?

Yes. DALI's scene and group recall functions make the ELG-200-42DA well-suited for hospitality and public space lighting where preset scenes—such as day, evening, and night modes—are managed by a central controller. The 199.9W, 42V output supports substantial LED strip lengths in corridor or cove lighting applications.

Does the ELG-200-42DA carry the certifications needed for EU and North American commercial lighting projects?

Yes. The sheet lists IEC/EN 61347-1, 61347-2-13 and EN62384 safety with EN55015, EN61000-3-2 Class C and EN61547 EMC compliance for the EU, and UL8750 (Type HL) and CSA C22.2 No. 250.13-12 for the US and Canada, plus DALI compliance to IEC62386-101 and 102, making it suitable for multinational commercial projects.
