Test conditions and notes14
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25β of ambient temperature.
- 2. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
- 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 βSTATIC CHARACTERISTICSβ 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. 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)
- 8. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80β or less.
- 9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
- 10. The ambient temperature derating of 3.5β/1000m with fanless models and of 5β/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 11. 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
- 12. 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.
- 13. ELG-150-12(except blank/A-Type) is used for any light source that exempt from the ErP-Directive (EU) 2019/2020 requirement, for example this model could be use for signalling products(including, but not limited to road-, railway-, marineorair traffic-signalling , traffic control or airfield lamps) .
- 14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ
What is the DALI interface on the ELG-150-24DA and what systems is it compatible with?
The DA suffix indicates this driver has a DALI (Digital Addressable Lighting Interface) input compliant with IEC 62386-101 and -102. DALI is a two-wire digital bus used in commercial building lighting control systems, allowing each driver on the bus to be individually addressed and dimmed from a DALI controller without additional analog wiring.
Can the ELG-150-24DA be used to retrofit DALI-controlled LED strip lighting in a commercial office?
Yes. The ELG-150-24DA is designed for this use case. It accepts DALI commands to smoothly dim 24V LED strips and can be individually addressed on a shared DALI bus, enabling scene control and occupancy-based dimming as expected in commercial office environments.
Is the ELG-150-24DA suitable for outdoor DALI-controlled signage or facade lighting?
Yes. The IP67 waterproof rating allows the ELG-150-24DA to be placed in outdoor enclosures subject to rain and moisture. Combined with its -40Β°C to +90Β°C case temperature (Tcase) range, it is appropriate for outdoor DALI lighting networks controlling facade strips or illuminated outdoor signs.
How much 24V LED strip can the ELG-150-24DA support?
The driver delivers up to 150W at 24V (6.25A maximum). For a 9.6 W/m strip, that supports approximately 15.6 m (150 Γ· 9.6). For a 20 W/m high-output strip, about 7.5 m (150 Γ· 20). Confirm your strip's rated wattage per meter before sizing the installation.
Can the ELG-150-24DA replace a non-dimmable 24V driver in an existing LED strip installation if DALI control is added later?
Yes, electrically: it is rated 150W at 24V / 6.25A like the non-dimming ELG-150-24. The sheet does not state the output level when no DALI signal is connected, so confirm that before installing; adding a DALI controller and bus wiring to the DA+/DA- leads later enables dimming without replacing the driver again.
Does the ELG-150-24DA work across a wide mains input range, including 277V?
Yes. The input range is 100β305VAC, accommodating all common single-phase supply voltages from 120V to 277V without any selector switch. This makes it suitable for North American commercial buildings wired at 277V as well as international 230V installations.
