Test conditions and notes11
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  3. 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. 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. 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. 6. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  7. 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. 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. 10. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
  10. 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.
  11. 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-L-AB for a high-voltage LED downlight array?

Yes, if the downlight requires 1400mA constant current and the LED load operates within the 116-232V CC range. Because this is a constant current driver, it should be matched to LED modules that specify current regulation rather than constant voltage input.

Is the ELGC-300-L-AB suitable for dimmable signage LED arrays?

It can be suitable when the signage array is a constant current load rated for 1400mA and falls within the 116-232V range. This version is adjustable and dimmable, which makes it a fit for applications that need output control with a constant current driver.

Can this driver power a small LED array with many LEDs in series?

Yes, if the array is designed for 1400mA constant current and its total forward voltage stays within 116V to 232V. The exact number of LEDs depends on each LED forward voltage, so the load must be evaluated by voltage range rather than a fixed LED count.

What should I match when selecting LEDs for the ELGC-300-L-AB?

Match the LED load to 1400mA constant current and a total forward voltage within the 116-232V constant current range. The number of LEDs depends on the forward voltage of each LED, which is why this driver should not be selected by LED count alone.

Is the ELGC-300-L-AB appropriate for outdoor conditions?

Yes, it has an IP67 waterproof rating, which is suitable for outdoor and wet environments. It is also rated for a working case temperature (Tcase) of -40°C to +85°C, supporting use in a wide temperature range.
