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 the ELG-75-C500AB power LED downlights in a building with a 0–10V lighting control system?

Yes. The AB-suffix combines output current adjustment with three-in-one dimming, which includes 0–10V, 10V PWM, and resistance interfaces. This makes it compatible with standard 0–10V dimming systems used in commercial downlight retrofits. Output current is 500mA with a CC voltage range of 75–150V.

Is the ELG-75-C500AB suitable for outdoor LED signage requiring dimming control?

The ELG-75-C500AB is rated IP65 water-resistant, suitable for outdoor signage cabinets protected from direct rain but not submersion. Its -40°C to +85°C working case temperature (Tcase) range and 100–305VAC input cover most outdoor signage environments worldwide. The built-in dimming interface enables schedule-based brightness control for signage.

Can this driver be used in a small LED array for a refrigerated display case?

Yes. With a minimum working case temperature of -40°C and an IP65 rating, the ELG-75-C500AB is appropriate for refrigerated display lighting. Note that the working humidity rating is 20–95% RH non-condensing.

How many LEDs can I connect to the ELG-75-C500AB in series?

The CC voltage range is 75–150V. The number of LEDs in the series string depends on the forward voltage of each individual LED. Add up the forward voltages of your intended string and confirm the total falls within 75–150V before finalizing the design.

What is the difference between the ELG-75-C500AB and the ELG-75-C500B?

Both are 75W, 500mA constant current drivers with three-in-one dimming and a 75–150V CC range. The ELG-75-C500AB adds a potentiometer for output current adjustment and is rated IP65 (water-resistant), while the ELG-75-C500B is rated IP67 (waterproof, including temporary immersion). Choose the C500B for applications requiring higher ingress protection.

What certifications does the ELG-75-C500AB hold?

The ELG-75-C500AB meets UL8750 (Type HL), CSA C22.2 No. 250.13-12, BS EN/EN/AS/NZS 61347-1 and 61347-2-13, BS EN/EN62384, GB/T19510, EAC and KC safety standards, supporting compliance in North American, European, Australian, and Chinese markets.
