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

FAQ

Is the ELG-75-C1400A-3Y suitable for outdoor LED luminaires in wet or coastal locations?

Yes. The ELG-75-C1400A-3Y is rated IP65, protecting against water jets and dust ingress. Its working case temperature (Tcase) range is -40°C to +85°C, accommodating both cold climates and warmer outdoor installations such as coastal area lighting and open-air facility lighting.

Can the ELG-75-C1400A-3Y power LED modules in mid-power LED downlights?

Yes. The ELG-75-C1400A-3Y outputs 1.4A constant current at up to 75.6W within a constant current region of 27–54V. LED modules designed for 1.4A operation with a forward voltage within the driver's output range are compatible, and the number of series LEDs depends on each LED's individual forward voltage.

What does the '3Y' suffix on the ELG-75-C1400A-3Y indicate?

The '3Y' suffix indicates the 3-wire input model: the input cable carries AC/L, AC/N and a PE (green/yellow) earth conductor. The ELG-75-C1400A-3Y otherwise shares the same 75.6W power, constant-current operation, and IP65 rating as the standard ELG-75-C1400A variant.

Can the ELG-75-C1400A-3Y be used to power LED track lighting in commercial retail spaces?

Yes. At 75.6W and 1.4A constant current, the ELG-75-C1400A-3Y is well sized for powering LED track light modules or spot arrays in commercial retail and display environments. Its wide 100–305VAC input handles both 120V and 277V commercial power circuits.

How does the ELG-75-C1400A-3Y compare to the standard ELG-75-C1400A?

Both are rated at 75.6W (60.2W at 100–180VAC) with 1400mA output, a 27–54V constant current region, 61V max. open circuit voltage, a Tcase range of -40°C to +85°C, IP65, and dimensions of 180 × 63 × 35.5 mm. The difference is the input wiring: the -3Y has a 3-wire input cable (AC/L, AC/N and PE), while the standard ELG-75-C1400A has a 2-wire input cable.

Is the ELG-75-C1400A-3Y appropriate for LED lighting in industrial processing environments?

Yes, within its ratings. The ELG-75-C1400A-3Y operates at case temperatures up to +85°C (Tcase), with output derating at higher ambient temperatures per the load vs temperature curve, so it can serve LED luminaires in industrial processing areas. The IP65 rating provides protection against dust and water jets common in these settings.
