Test conditions and notes12
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
- 2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
- 3. 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)
- 4. This series meets the typical life expectancy >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is 70℃ or less.
- 5. To fulfill requirements of the latest ErP regulation for lighting fixture, this LED driver can only be used behind a switch without permanently connected to the mains.
- 6. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
- 7. 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).
- 8. 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
- 9. Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA type.
- 10. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
- 11. Products sourced from the Americas regions may not have the ENEC/BIS/CCC/KC logo. Please contact your MEAN WELL sales for more information.
- 12. For A/AB/ADA type need to consider build in using to comply with Type HL application

FAQ
Can I use the ELGC-300-M-A for high-power LED downlights?
Yes, if the downlight uses a constant current driver at 2800mA and its LED load stays within the 58-116V constant current range. This model is a constant current LED driver, so it is suited to downlights built for regulated current rather than constant voltage operation.
Is the ELGC-300-M-A suitable for LED signage modules?
It can work with signage modules only when the module assembly is designed for 2800mA constant current input and the combined forward voltage falls within 58-116V. It is not the right choice for signage products that expect a constant voltage power supply.
Can this driver power a small LED array for display or architectural lighting?
Yes, for a small LED array that is specified for 2800mA constant current operation and fits inside the 58-116V CC range. The exact number of LEDs depends on the forward voltage of each LED, not on a fixed LED count.
Will the ELGC-300-M-A work in outdoor or damp locations?
It is rated IP67 waterproof, so it is built for environments where dust and water protection matter. It also has a working case temperature (Tcase) range of -40°C to +85°C, which supports demanding indoor or outdoor conditions.
How do I know if my LED load is compatible with this 2800mA driver?
Your LED load needs to be designed for constant current at 2800mA, with a total forward-voltage requirement inside the 58-116V output range. The number of LEDs it can run depends on each LED's forward voltage, so compatibility is determined by the full load voltage rather than a specific LED count.
How does the ELGC-300-M-A compare with other ELGC-300 current options?
Within the ELGC-300 family, H versions are 301W at 5600mA with a 29-58V constant current range, M versions are 301W at 2800mA with a 58-116V range, and L versions are 301W at 1400mA with a 116-232V range. The A, AB and ADA suffixes are sibling variants within those same electrical platforms.
