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

Can the ELG-75-C500B drive LED downlights in a damp or wet location that also requires dimming?

Yes. The ELG-75-C500B combines IP67 waterproof protection with three-in-one dimming (0–10V, 10V PWM, and resistance), making it suitable for wet-location downlight installations that need brightness control. It delivers a constant 500mA within a CC voltage range of 75–150V.

Is this driver appropriate for outdoor LED signage with variable brightness requirements?

Yes. The IP67 rating and -40°C to +85°C working case temperature (Tcase) range allow the ELG-75-C500B to be installed in exposed outdoor signage enclosures. The three-in-one dimming interface supports automated brightness scheduling via 0–10V, 10V PWM, or resistance control signals.

Can the ELG-75-C500B be installed in a cold-storage facility requiring dimming control?

Yes. The -40°C minimum working case temperature and IP67 waterproof rating make the ELG-75-C500B suitable for freezer and cold-room environments. The dimming capability allows light levels to be reduced during off-peak periods to save energy.

How many LEDs can I power in series with the ELG-75-C500B?

The CC voltage range is 75–150V. The series string length is determined by the forward voltage of each LED you are using; the sum of all forward voltages must fall within 75–150V. Consult your LED datasheet for the typical forward voltage at 500mA to calculate the correct string length.

How does the ELG-75-C500B compare to the ELG-75-C500AB for outdoor applications?

Both are 75W, 500mA constant current drivers with three-in-one dimming and a 75–150V CC range; the AB also adds potentiometer current adjustment. For outdoor use the key difference is IP rating: the ELG-75-C500B is IP67 (waterproof, temporary immersion rated), while the ELG-75-C500AB is IP65 (water-resistant, no immersion). For outdoor or wet-area installations, the ELG-75-C500B offers a higher level of protection.

What certifications does the ELG-75-C500B carry?

The ELG-75-C500B 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, covering the major regulatory markets including North America, Europe, Australia, and China.

Can the ELG-75-C500B operate on both 120V and 277V commercial mains supplies?

Yes. The universal input range of 100–305VAC means the ELG-75-C500B accepts 120V residential, 208V, 230V European, and 277V commercial supplies without modification. No manual voltage selection is required; note that rated power is 60W at 100–180VAC and 75W at 200–305VAC.
