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 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. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
7. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
9. 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).
10. 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
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-240H-C2100A to drive high-current LED downlight modules?

Yes. The HLG-240H-C2100A delivers a constant 2100mA across a CC voltage range of 59-119V, providing up to 249.9W. It is designed for LED modules that require a high drive current, such as COB LED downlights or multi-chip arrays. The adjustable output potentiometer lets you reduce the current below 2100mA if your LEDs need less.

Is the HLG-240H-C2100A suitable for powering LED grow light panels?

Yes. At 2100mA and 249.9W, it can drive a significant array of high-power LEDs for horticultural lighting. The CC voltage range of 59-119V accommodates various series configurations of grow light COBs. The adjustable output lets you tune the current for optimal light intensity and LED lifespan during different growth phases.

Can I use the HLG-240H-C2100A for high-brightness LED signage modules?

Yes, as long as the modules' total series forward voltage falls within 59-119V at 2100mA. The 249.9W capacity supports high-brightness sign modules that demand substantial current. The adjustable output potentiometer allows you to reduce brightness at installation without needing an external dimmer.

How does the output adjustment work on the HLG-240H-C2100A?

The A suffix indicates a built-in potentiometer that lets you reduce the output current below the rated 2100mA. This is useful for fine-tuning LED brightness at installation or matching the driver to LEDs with a lower optimal drive current. The adjustment is manual and does not provide remote dimming. For remote dimming, use the -C2100AB or -C2100B variant.

Can the HLG-240H-C2100A operate in a hot indoor environment like a factory ceiling?

Yes, with care. The driver's case temperature (Tcase) is rated up to +90°C, but output must be derated at elevated ambient temperatures per the derating curve, and the typical life expectancy of >62,000 hours applies when the tc point is about 75°C or less. Ensure airflow around the driver is not blocked so it can shed heat at full 249.9W load.
