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-C700A power LED downlights where some output current adjustment is needed on-site?

Yes. The ELG-100-C700A is an adjustable variant of the C700 family, meaning the output current can be trimmed after installation to fine-tune brightness. It delivers up to 700mA constant current across a 71–143V CC output range at 100.1W, which suits multi-chip downlights and compact LED arrays.

Is the ELG-100-C700A suitable for outdoor LED signage installations?

It can be used in outdoor locations that are sheltered from direct water spray, but this model carries an IP65 rating rather than IP67, so it is water-resistant rather than waterproof against temporary immersion. For direct outdoor exposure without any enclosure, the fully waterproof IP67 ELG-100-C700 or ELG-100-C700B may be a better fit.

How does the ELG-100-C700A differ from the standard ELG-100-C700?

The ELG-100-C700A adds an output current adjustment feature, allowing the drive current to be set below the rated 700mA to reduce LED brightness or adapt to a specific LED load, whereas the ELG-100-C700 has a fixed output. The ELG-100-C700A is rated IP65 (water-resistant) compared to the IP67 (waterproof) rating of the ELG-100-C700. Electrical specs — 100.1W, 700mA, 71–143V CC range — are the same.

What LED string configurations are compatible with the ELG-100-C700A?

Any LED string whose total forward voltage falls between 71V and 143V is compatible. The driver maintains 700mA (or a reduced setting if adjusted) through that string. The number of LEDs in series depends on each individual LED's forward voltage and cannot be stated as a fixed number.

Can I use the ELG-100-C700A for a small indoor LED array in a retail display?

Yes. At 100.1W and 700mA constant current it has sufficient capacity for a compact retail LED array, and the adjustable output lets you set brightness to match the display requirements. The IP65 rating is adequate for a dry indoor environment, and the metal enclosure keeps the footprint manageable at 199 × 63 × 35.5 mm.
