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 the ELG-75-C1050A power LED downlights in a covered outdoor area or parking structure?

Yes. The ELG-75-C1050A carries an IP65 water-resistant rating, which protects against low-pressure water jets and dust ingress. This makes it suitable for covered outdoor areas such as parking structures, canopies, or exterior soffits where direct rain contact is unlikely but moisture and humidity are present.

Is the ELG-75-C1050A suitable for driving LEDs in small signage modules?

Yes. As a constant-current driver outputting 1050mA across a CC voltage range of 35–71V, the ELG-75-C1050A is well matched to LED signage modules wired in series. Its 74.55W capacity supports small to medium LED sign arrays, and its 180 × 63 × 35.5 mm case fits compact sign cabinets.

What LED arrays is the ELG-75-C1050A compatible with?

The ELG-75-C1050A operates in constant-current mode at 1050mA with a CC output voltage range of 35–71V. It is compatible with any LED load whose forward voltage falls within that range at 1050mA; the number of LEDs in series depends on each LED's forward voltage and is not fixed to a specific count.

Can this driver be used for LED retrofit downlights in commercial office spaces?

Yes. The ELG-75-C1050A's 74.55W output at 1050mA is typical for mid-power LED downlight modules used in commercial offices. The adjustable output current and wide 100–305VAC input allow use on both 120V and 277V commercial wiring systems.

Does the ELG-75-C1050A support output current adjustment?

Yes. The 'A' suffix indicates this model includes output current adjustment via a built-in potentiometer, allowing the drive current to be trimmed from the rated 1050mA down to 525mA. This is useful when matching the driver to LEDs with specific current requirements or when designing for reduced lumen output.

What is the operating temperature range of the ELG-75-C1050A, and does it suit cold-storage lighting?

The ELG-75-C1050A works at case temperatures (Tcase) from -40°C to +85°C, which covers cold-storage refrigeration environments; at high ambient temperatures the output load derates per the load vs temperature curve. The IP65 rating protects against dust and water jets; working humidity is rated 20–95% RH non-condensing.
