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".
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 power supply 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-240-C2100 drive high-power LED arrays in industrial high-bay lighting?

Yes. At 2100mA constant current output and 241.5W, the ELG-240-C2100 is well suited for high-power LED modules used in industrial high-bay luminaires. Its CC voltage range of 57–115V accommodates a range of module string configurations, and the series' IP65/IP67 enclosure suits installation in factory environments with dust and occasional water exposure.

Is the ELG-240-C2100 suitable for outdoor LED floodlights or sports lighting?

Yes. The ELG-240-C series' IP65/IP67 rating allows the driver to be mounted inside outdoor floodlight enclosures or stadium luminaires exposed to rain and humidity. The case temperature (Tcase) rating of -40°C to +85°C supports both cold-weather outdoor arenas and hot-climate installations, with load derating at high temperatures.

What LED string voltage range is compatible with this driver?

The ELG-240-C2100 maintains a constant 2100mA output while its voltage adjusts automatically between 57V and 115V. The number of LEDs that can be connected in series depends on the forward voltage of each individual LED; the combined string voltage must fall within the 57–115V regulation window.

Can this driver be used in cold-storage LED lighting applications?

Yes. With a rated case temperature down to -40°C and the series' IP65/IP67 seal, the ELG-240-C2100 can be installed in freezer warehouses, cold rooms, or blast-chill facilities. Note the sheet specifies working humidity of 20–95% RH non-condensing.

Is the ELG-240-C2100 appropriate for LED modules in large outdoor signage installations?

Yes. The 2100mA output at up to 241.5W is capable of driving large sign-module arrays, and the series' IP65/IP67 rating protects the enclosure against outdoor weathering, dust accumulation, and rain. The wide universal input of 100–305VAC means no input-side voltage matching is needed for international sign projects.

Does the ELG-240-C2100 support dimming or output adjustment?

No. The base ELG-240-C2100 model does not include a dimming interface or output adjustment potentiometer. Sibling variants with suffixes A (adjustable), B (dimmable), AB (adjustable and dimmable) or DA (DALI) are available at the same power and current rating if dimming capability is required.

How does the 2100mA output of the ELG-240-C2100 compare to other current options in the 240W ELG-240 CC family?

The ELG-240 constant current family offers five current options at approximately 240W: 700mA (C700), 1050mA (C1050), 1400mA (C1400), 1750mA (C1750), and 2100mA (C2100). Higher current variants operate at lower output voltages — the C2100 runs at 57–115V, while the C700 runs at a higher voltage range. Select the variant whose current matches your LED module's rated drive current.
