Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
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. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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. 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. 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. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
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. 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. 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. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-100-C500AB be used in a dimmable LED downlight installation with a 1–10V control system?

The AB suffix means this driver supports both output current adjustment and three-in-one dimming (0–10VDC, 10V PWM, and resistance). Its analog input is specified for 0–10V rather than 1–10V, so confirm your 1–10V controller's compatibility before use in commercial and hospitality downlight systems.

Is the ELG-100-C500AB suitable for LED signage modules that require field-adjustable current levels?

Yes. The built-in potentiometer allows the output current to be trimmed between 250mA and 500mA to match the LED module's optimal drive level, while the dimming inputs enable dynamic brightness control after installation. The IP65 rating and wide input range of 100–305VAC make it appropriate for a variety of signage enclosure environments.

What is the difference between the ELG-100-C500AB and the ELG-100-C500A?

Both models offer output current adjustment via a trimmer potentiometer. The ELG-100-C500AB adds dimming capability (0–10V, PWM, resistance) that the ELG-100-C500A does not have. Both are rated IP65 and share the same 100W, 500mA, 100–200V CC specifications.

How many LEDs can I connect in series to the ELG-100-C500AB?

The CC voltage range is 100–200V. Connect LEDs in series such that the total string forward voltage falls within that range. The number of LEDs depends on each LED's forward voltage — do not assume a fixed count without checking your specific LED's datasheet.

Can the ELG-100-C500AB be installed in a partially exposed outdoor location?

The driver's IP65 rating protects against dust and water jets, making it suitable for sheltered outdoor or semi-outdoor locations such as covered walkways, outdoor corridors, and canopy fixtures. For fully exposed or submersion-risk environments, the IP67-rated ELG-100-C500B would be the more appropriate choice.
