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. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. 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.
7. 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)
8. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. 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).
11. 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

FAQ

What does the -3Y designation mean on the ELG-75-24-3Y, and how does it affect use?

The -3Y suffix indicates a 3-wire input (line, neutral, protective earth), and the datasheet asks for the case to be connected to PE for complete EMC performance and safe use, which aligns with commercial wiring that includes a ground conductor. The rest of the electrical performance—75.6W at 24V—is equivalent to the base ELG-75-24 model.

Can the ELG-75-24-3Y be installed in an outdoor wet-location enclosure?

Yes. The ELG-75 series is rated IP65 or IP67, making it suitable for outdoor sign boxes, landscape fixtures, or building-facade enclosures exposed to rain and humidity. Its -40°C to +85°C case-temperature range covers extreme seasonal temperature variation.

How many meters of 24V LED strip can the ELG-75-24-3Y power?

The ELG-75-24-3Y outputs 75.6W at 24V on 200–305VAC input (60W on 100–180VAC). For a 10 W/m strip, that allows up to 7.5 meters; for a 14.4 W/m strip, approximately 5.2 meters. Check your strip's rated power per meter and apply a 20% derating margin for reliable continuous operation.

Is the ELG-75-24-3Y suitable for powering 24V LED strip in a commercial kitchen or food-service area?

Yes, when kept away from direct heat and steam. The series' IP65/IP67 rating protects against splashes, and the -40°C to +85°C case-temperature range covers walk-in coolers; near cooking equipment keep the case below +85°C (ideally about 70°C for the >50,000-hour life expectancy), and note the humidity rating is non-condensing.

Can the ELG-75-24-3Y be used to drive 24V LED strip for architectural feature lighting in a lobby?

Yes. At 75.6W and 24V, this driver supports LED strip runs in lobby coves, column accents, or backlit feature walls. The 3-wire input is convenient when the driver is wired from a commercial electrical panel with a ground conductor already run to the circuit.
