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-H-A for high-output LED downlights?

Yes, if the downlight requires a constant-current driver at 5600mA and the LED load operates within the 29-58V constant-current range. With 301W output, this model is intended for high-power LED assemblies rather than small constant-voltage fixtures.

Is the ELGC-300-H-A suitable for powering larger signage LED modules?

It can be used for signage modules when the lighting system is built as a constant-current load at 5600mA. It is not a constant-voltage supply, so it is not the right choice for signage modules that require a fixed-voltage input.

Can this driver run a high-power small LED array for commercial lighting?

Yes, if the LED array is specified for 5600mA constant current and its total forward voltage stays within 29-58V. The 301W power rating supports much larger LED arrays than lower-wattage drivers in the same general category.

Is the ELGC-300-H-A appropriate for damp or outdoor environments?

This model has an IP67 waterproof rating and a working case temperature (Tcase) range of -40°C to +85°C. That makes it suitable for demanding damp or outdoor environments where a sealed, waterproof driver is needed.

What is the difference between the ELGC-300-H-A and the other ELGC-300 current ranges?

The ELGC-300 family is split by output current and constant-current range: ELGC-300-H models are 5600mA with 29-58V and 301W, ELGC-300-M models are 2800mA with 58-116V and 301W, and ELGC-300-L models are 1400mA with 116-232V and 301W. The ELGC-300-H-A is the high-current, lower-voltage version in that 300W family.
