Test conditions and notes10

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.

FAQ

What does the -3Y suffix mean on the ELG-75-C1400B-3Y, and why would I choose it over the standard B variant?

The -3Y designation indicates the 3-wire input model: its input cable carries AC/L, AC/N and a PE (green/yellow) earth conductor, so the case can be connected to protective earth. It is otherwise the same as the ELG-75-C1400B in its constant current operation and IP67 waterproof rating. Choose the -3Y when your installation calls for an earthed 3-wire input connection.

Can the ELG-75-C1400B-3Y be used to drive LED downlights in a hospitality or commercial space with a lighting control system?

Yes. The ELG-75-C1400B-3Y operates in constant current mode at 1.4A output, and its B-type dimming interface supports 0–10V, 10V PWM, and resistance control signals. This makes it compatible with most commercial lighting control systems used in hospitality, retail, and office installations.

Is the ELG-75-C1400B-3Y suitable for outdoor LED signage in rainy climates?

Yes. The ELG-75-C1400B-3Y carries an IP67 waterproof rating, providing dust protection and resistance to temporary water submersion. This level of protection is appropriate for outdoor LED signage enclosures exposed to rain and moisture in temperate or tropical climates.

What is the operating temperature range for the ELG-75-C1400B-3Y, and can it be used in unheated outdoor enclosures?

The ELG-75-C1400B-3Y is rated for a working case temperature (Tcase) of -40°C to +85°C, which covers unheated outdoor enclosures in northern climates; at high ambient temperatures the load derates per the load vs temperature curve. The -40°C lower limit makes it suitable for cold-start applications in extreme winter conditions.

Can the ELG-75-C1400B-3Y drive LED modules in a series string for architectural LED array applications?

Yes. As a constant current driver, the ELG-75-C1400B-3Y maintains a stable 1.4A output regardless of load variation, making it well suited for series-connected LED module strings in architectural lighting arrays. The number of LEDs that can be accommodated in the string depends on each LED's forward voltage.
