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-C1050AB be used in a 240W LED downlight system with a 0–10V dimming controller?
Yes. The 'AB' designation indicates both output adjustment and analog dimming support, compatible with 0–10V and PWM dimming signals. At 1050mA constant current and 239.4W, it can handle large downlight arrays or multiple fixtures sharing a single driver when system forward voltages fall within 114–228V.
Is the ELG-240-C1050AB suitable for LED signage modules that need both brightness trimming and field dimming?
Yes. The adjustable output allows factory or field trimming of the 1050mA set point, while the built-in dimming input enables dynamic brightness control via an external signal. This combination is useful for signage installations where initial calibration and ongoing operational dimming are both required.
Can the ELG-240-C1050AB power LED modules in a theatrical or architectural mood-lighting application?
The ELG-240-C1050AB's analog dimming makes it appropriate for architectural or theatrical LED fixtures where smooth, continuous brightness control is needed. Its 239.4W, 1050mA constant current output with a 114–228V CC range suits high-power LED modules used in stage wash lights or large architectural installations.
What LED string configuration is compatible with the ELG-240-C1050AB?
This driver outputs 1050mA constant current with a CC voltage range of 114–228V. LED loads must be connected in series so that the combined string forward voltage at 1050mA falls within 114–228V. The number of LEDs in the string is determined by each LED's forward voltage at the operating current.
How does the ELG-240-C1050AB compare to the ELG-240-C1050 base model and the ELG-240-C1050A?
The ELG-240-C1050 is a fixed-output, non-dimmable unit. The ELG-240-C1050A adds output current adjustment. The ELG-240-C1050AB (this unit) further adds analog dimming capability on top of the adjustment. All three share 239.4W, 1050mA output, and the same 114–228V CC range.
Can the ELG-240-C1050AB be used in damp indoor locations such as food-processing facilities?
The ELG-240-C series is rated IP65 or IP67, protecting against dust and water. It is rated for a case temperature (Tcase) of -40°C to +85°C. This makes it suitable for damp indoor locations such as food-processing facilities, wash areas, or cold-storage anteroom lighting.
