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. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
  3. 3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  4. 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. 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. 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. 7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  8. 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. 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. 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. 11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-100-C500 power a medium-voltage LED signage module array?

Yes. The ELG-100-C500 outputs a constant 500mA with a CC voltage range of 100–200V, making it compatible with mid-voltage LED module strings used in illuminated signage. Its IP67 waterproof metal case also enables mounting in outdoor or semi-outdoor sign cabinets.

Is the ELG-100-C500 suitable for use in an LED downlight fixture for retail or hospitality lighting?

Yes. Delivering 100W at a constant 500mA (70W on 100–180VAC input), this driver is appropriate for LED downlight engines designed for higher-current operation within the 100–200V string range. The wide input of 100–305VAC means it can be deployed in international projects without modification.

Can I install the ELG-100-C500 in an outdoor landscape or pathway lighting fixture?

Yes. The IP67 waterproof rating and case temperature (Tcase) rating of -40°C to +90°C allow for outdoor installation in landscape, pathway, or architectural lighting applications. The driver's 100W output supports LED arrays in larger outdoor luminaires.

What is the difference between the ELG-100-C500 and the ELG-100-C350 in terms of application fit?

The ELG-100-C500 outputs 500mA with a CC voltage range of 100–200V and 100W total power, while the ELG-100-C350 outputs 350mA at a CC voltage range of 143–286V with 100.1W. The C500 is suited to LED loads requiring higher current at lower string voltages, whereas the C350 covers higher-voltage, lower-current LED strings. Both are IP67 constant current drivers within the ELG-100 family.

How many LEDs can the ELG-100-C500 support in a series string?

The CC voltage range is 100–200V. The number of LEDs in a series string depends on each LED's individual forward voltage — the total string forward voltage must fall within 100–200V for the driver to regulate properly at 500mA. Refer to your LED's datasheet for the forward voltage value to calculate the compatible string length.
