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

Can I use the ELG-75-C350B to drive LED downlights in a commercial lighting installation?

Yes. The ELG-75-C350B operates as a constant current driver at 350mA, which is a standard current level for many LED downlight modules. Its 74.9W output and CC voltage range of 107–214V allows it to support series strings of LEDs whose combined forward voltage falls within that range. The IP67 rating also makes it suitable for recessed or damp-location downlight housings.

Is the ELG-75-C350B suitable for outdoor LED signage modules?

Yes. With an IP67 waterproof rating and a working case temperature (Tcase) range of -40°C to +85°C, the ELG-75-C350B can be installed in exposed outdoor environments. It accepts 100–305VAC input, making it compatible with worldwide mains voltages commonly used in outdoor signage cabinets.

Can I use this driver for a small LED array in a cold storage or freezer environment?

Yes. The ELG-75-C350B is rated for operation down to a case temperature of -40°C, so it is appropriate for cold storage, freezer rooms, or outdoor installations in cold climates. The IP67 rating also protects against dust and moisture ingress.

Does the ELG-75-C350B support dimming, and what dimming methods are available?

Yes. The B-suffix variant has a three-in-one dimming interface accepting 0–10VDC, a 10V PWM signal, or resistance. This allows the driver to be integrated into lighting control systems that use any of these signals for brightness adjustment. Output current can be dimmed down from the full 350mA level to a minimum of about 8%.

How many LEDs can the ELG-75-C350B drive in series?

The CC voltage range is 107–214V, so the number of LEDs in a series string depends on each LED's forward voltage. Divide the usable voltage window by the forward voltage of your specific LED to determine how many can be connected in series. Do not pair with a string whose total forward voltage falls outside the 107–214V range.

What certifications does the ELG-75-C350B carry?

The ELG-75-C350B 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. This broad coverage makes it suitable for projects requiring compliance with North American, European, Australian, and Chinese market requirements.

How does the ELG-75-C350B compare to the ELG-75-C350 and ELG-75-C350DA within the same current family?

Within the ELG-75 350mA family, the ELG-75-C350 has no dimming, the ELG-75-C350B adds three-in-one dimming (0–10V, 10V PWM, resistance), and the ELG-75-C350DA adds DALI dimming. All share the same 74.9W, 350mA constant current output, 107–214V CC range and 224V max. open circuit voltage; the variants differ only in dimming method.
