Frequently asked questions
1. Can ELG-300-24A deliver 300W on 115V mains?
The specification lists 255W and 10.63A for 100–180VAC input. The 300W, 12.5A rating applies at 200–305VAC.
2. What output settings can be adjusted?
The voltage adjustment range is 22.4–25.6V, and the current adjustment range is 6.25–12.5A. The permitted load still depends on input and temperature conditions.
3. Is this driver constant voltage or constant current?
It supports both modes, with a nominal 24V output and a 14.4–24V constant-current region. Check the LED load against the operating curve.
4. What should I check when replacing an ELG-300 supply?
Confirm ELG-300-24A on the label, the mains voltage, load current, mounting dimensions and wiring. Use the PDF to check derating and the correct output setting.
