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 driver 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 AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the ELG-75-C1400AB to drive LED downlights in a commercial ceiling installation?

Yes. The ELG-75-C1400AB outputs 1400mA constant current across a 27–54V operating range, making it compatible with LED downlight arrays that fall within that voltage window. At 75.6W total capacity, it suits small to mid-size LED downlight clusters where individual LED forward voltage determines how many can be driven in series.

Is the ELG-75-C1400AB suitable for powering LED signage modules outdoors?

The ELG-75-C1400AB carries an IP65 water-resistance rating, which provides protection against dust ingress and low-pressure water jets. It is appropriate for sheltered outdoor signage enclosures but should not be directly exposed to rain or submersion; for fully exposed outdoor installations, the IP67-rated ELG-75-C1400B would be a better fit.

Can I connect this driver to a 0–10V dimming system for lighting control?

Yes. The AB suffix indicates this unit includes both the output-adjustment potentiometer (A feature) and the built-in 3-in-1 dimming interface (B feature), supporting 0–10V, 10V PWM, and resistance dimming signals. This allows integration with most commercial lighting control systems that output any of those signal types.

Will the ELG-75-C1400AB operate correctly on a 277V commercial supply?

Yes. The ELG-75-C1400AB accepts an input range of 100–305VAC, which covers 120V North American residential, 230V European, and 277V US commercial supplies without any manual voltage selection.

How does the ELG-75-C1400AB differ from the ELG-75-C1400A and ELG-75-C1400B?

All three variants share the same 75.6W / 1400mA output and 27–54V CC voltage range. The ELG-75-C1400A (adjustable only) adds an output potentiometer; the ELG-75-C1400B (dimmable only) adds a 3-in-1 dimming interface (0–10V, PWM, resistance); and the ELG-75-C1400AB combines both features. The ELG-75-C1400A and ELG-75-C1400AB are IP65 rated, while the ELG-75-C1400B is IP67 rated.

What is the operating temperature range for the ELG-75-C1400AB, and can it be used in cold storage areas?

The ELG-75-C1400AB is rated for a working case temperature (Tcase) of -40°C to +85°C. This range comfortably covers cold-storage and refrigerated warehouse environments; at high ambient temperatures the output load derates per the load vs temperature curve.
