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-C1400AB drive dimmable LED downlights in a commercial office or hospitality setting?

Yes. The 'AB' suffix means it combines an analogue current-trim potentiometer with PWM/0–10V dimming input, making it suitable for commercial spaces where fixtures need both field-calibrated current levels and ongoing dimmer control. It outputs a constant 1400mA within a 86–171V range.

Is the ELG-240-C1400AB protected for use in semi-outdoor or covered parking structures?

The ELG-240-C series carries an IP65 or IP67 rating, protecting against dust and water. The ELG-240-C1400AB is appropriate for covered parking structures, loading docks, and canopied areas where direct rain does not reach but humidity and splash are present.

Can I use this driver to power LED modules in a retail display cabinet with adjustable brightness?

Yes. The built-in 0–10V or PWM dimming input allows continuous brightness adjustment for retail display lighting. The analogue trim also lets installers set maximum output current during initial setup, preventing over-driving LED modules.

How many LEDs can this driver support in a series string?

The output voltage range is 86–171V. You can calculate the number of series LEDs by dividing the available voltage span by the forward voltage (Vf) of your specific LED; the combined Vf of the entire string must stay within that 86–171V window.

How does the ELG-240-C1400AB differ from the ELG-240-C1400B?

Both models are 239.4W, 1400mA constant-current drivers with 3-in-1 dimming (0–10VDC / 10V PWM / resistance). The ELG-240-C1400AB adds a built-in potentiometer that lets you reduce output current (700–1400mA); the ELG-240-C1400B does not include this adjustment.

Can this driver be installed in a cold-climate outdoor cabinet?

Yes. The ELG-240-C1400AB is rated for a case temperature (Tcase) of -40°C to +85°C, which accommodates severe cold-climate outdoor installations. The series' IP65/IP67 enclosure provides moisture protection for outdoor cabinet environments.
