Test conditions and notes11

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. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. 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)
6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
8. 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).
9. 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
10. 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.
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-240-C1050 power a high-output LED array in an industrial or warehouse luminaire?

Yes. The ELG-240-C1050 delivers 239.4W at 1050mA constant current, making it suitable for high-flux LED arrays in high-bay or industrial fixtures. Its 100–305VAC input and the series' IP65/IP67 rating support deployment in demanding environments including damp or dusty warehouses.

Is the ELG-240-C1050 suitable for LED street lighting or outdoor area lighting?

Yes. The series' IP65/IP67 rating provides water and dust protection for outdoor installations, and the -40°C to +85°C case temperature (Tcase) rating covers extreme climates. The 1050mA constant current at up to 239.4W is commonly used in street and area lighting LED modules where higher forward current is preferred for fewer series LEDs.

Can this driver be used for large LED signage panels that require 240W-class power?

The ELG-240-C1050 is a constant current driver at 1050mA with a CC voltage range of 114–228V. For signage modules designed to operate at 1050mA, it provides 239.4W capacity with a fixed (non-dimmable, non-adjustable) output. Ensure the LED string forward voltage falls within 114–228V.

How many LEDs can the ELG-240-C1050 drive in a series string?

The ELG-240-C1050 outputs 1050mA constant current with a CC voltage range of 114–228V. The number of LEDs that can be connected in series is determined by the forward voltage of each LED at 1050mA. There is no fixed LED count — confirm your LED's Vf at operating current to calculate string length.

How does the ELG-240-C1050 differ from the ELG-240-C1050A and ELG-240-C1050AB?

All three are 239.4W, 1050mA constant current drivers with the same 114–228V CC range and 244×71×37.5 mm form factor. The ELG-240-C1050 is the fixed-output base model. The ELG-240-C1050A adds output current adjustment (trimming, 525–1050mA). The ELG-240-C1050AB further adds 3-in-1 dimming to the adjustable version.

Can the ELG-240-C1050 be installed in an outdoor luminaire exposed to rain and temperature extremes?

Yes. The series' IP65/IP67 rating protects against dust and water, and the case temperature (Tcase) rating of -40°C to +85°C covers both extreme cold and hot environments, with load derating at high temperatures per the sheet's curve. Follow MEAN WELL's IP waterproof installation cautions for outdoor luminaire installations.
