Test conditions and notes13

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. 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.

FAQ

Can the ELG-240-54 power a large run of 54V LED strip?

Yes. The ELG-240-54 delivers 240.3W at 54V and 4.45A on 200–305VAC input (180.36W on 100–180VAC). A 54V strip rated at 18W per meter allows approximately 13 meters per driver; at 24W per meter the limit is about 10 meters. Check your strip's rated power per meter and keep total load within the rating for your input voltage.

Is the ELG-240-54 suitable for permanent outdoor LED installations?

Yes. The series' IP65/IP67 rating confirms dust-tight, water-resistant protection, making this driver suitable for outdoor LED architectural lighting, facade illumination, and weatherproof signage enclosures.

Can I use the ELG-240-54 for high-bay LED lighting in an industrial facility?

Yes. With 240.3W output at 54V and a wide input of 100–305VAC (including 277VAC), this driver suits the mains supplies common in industrial facilities. The IP65/IP67 rating also provides protection in dusty or wet industrial environments.

Does the ELG-240-54 have dimming capability?

No. The base ELG-240-54 (no letter suffix) does not include a dimming interface. For adjustment or dimming at the same power and voltage, the A-type (adjustable output), B-type (three-in-one dimming), AB-type (both) or DA-type (DALI) variants of the ELG-240-54 are available.

What is the operating temperature range of the ELG-240-54?

The ELG-240-54 is specified for a case temperature (Tcase) of -40°C to +90°C; at rated current in constant-current mode the maximum ambient is 60°C. This range supports installations in cold outdoor climates as well as warm enclosed luminaire housings.

Is the ELG-240-54 appropriate for powering LED strips in refrigerated display cases or cold-room lighting?

Yes. The lower case temperature limit of -40°C means this driver will start and run in freezer or cold-room environments. The IP65/IP67 rating protects against moisture, but the working humidity is specified as 20–95% RH non-condensing, so avoid mounting it where condensation forms.
