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-C350A to fine-tune the drive current for different batches of LED signage modules?

Yes. The A suffix indicates the ELG-75-C350A includes an output-adjustment potentiometer that allows you to trim the constant current output within its rated range. This is useful when different LED module batches have slightly different forward voltage characteristics and need a calibrated current level for consistent brightness.

Is the ELG-75-C350A rated for damp or partially exposed outdoor locations?

The ELG-75-C350A carries an IP65 water-resistance rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. It is suitable for sheltered outdoor enclosures and covered signage cabinets but should not be directly submerged or exposed to persistent heavy rain without a protective housing. For fully exposed outdoor use, the IP67-rated ELG-75-C350 or ELG-75-C350B would be more appropriate.

Can the ELG-75-C350A power a series-connected array of LED modules for an architectural façade project?

Yes. The ELG-75-C350A operates in constant current mode at 350mA and supports a CC voltage range of 107–214V, making it suitable for longer series LED module strings used in architectural façade installations. The adjustable output also allows the installer to match the driver precisely to the LED array's operating point.

Does the ELG-75-C350A support any dimming interfaces?

No. The ELG-75-C350A provides output-level adjustment via an onboard potentiometer only; it does not include a 0–10V, PWM, resistance, or DALI dimming input. For a variant with built-in dimming, the ELG-75-C350AB (adjustable plus 3-in-1 dimming) would be the appropriate choice.

What certifications does the ELG-75-C350A hold, and is it approved for European markets?

The ELG-75-C350A meets the BS EN/EN 61347-1, 61347-2-13 and EN62384 safety standards and the EN55015 / EN61000 EMC standards used in Europe, along with UL8750 (Type HL) and CSA C22.2 No. 250.13-12 for North America, AS/NZS 61347 for Australia and New Zealand, GB/T19510 for China, EAC and KC.

Can the ELG-75-C350A be used in a cold storage or freezer-room LED lighting retrofit?

Yes. The ELG-75-C350A is rated for a working case temperature (Tcase) of -40°C to +85°C, which covers the temperature ranges found in commercial freezer rooms and cold storage facilities. Its constant current output at 350mA is compatible with LED modules commonly used in those environments.
