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-C1050AB for dimmable LED high-bay lighting in a warehouse?

Yes. The HLG-240H-C1050AB delivers 1050mA constant current at 249.9W with both adjustable output and 1-10V/PWM dimming. This suits high-bay fixtures where brightness needs to change based on occupancy or daylight levels. The LED string voltage must fall within the 119-238V CC range.

Is the HLG-240H-C1050AB suitable for dimmable commercial LED panel arrays?

Yes. At 249.9W and 1050mA, it powers medium-to-large LED panel arrays with series string voltages between 119V and 238V. The dimming input integrates with building management systems for scheduled or sensor-driven brightness control, and the adjustable output lets you calibrate current to your panels' optimal operating point.

Can the HLG-240H-C1050AB drive LED modules for large illuminated signage with dimming?

Yes. The 1050mA constant current output handles large sign module arrays whose combined forward voltage stays within 119-238V. The 1-10V/PWM dimming input enables day/night brightness scheduling, and the adjustable output trims current to match your specific LED module requirements.

What dimming methods does the HLG-240H-C1050AB support?

The HLG-240H-C1050AB accepts 1-10V analog and PWM dimming signals through its built-in dimming input. This allows integration with standard wall dimmers, lighting controllers, and building automation systems. The adjustable output potentiometer provides an additional level of static current calibration independent of the dimming signal.

How does the HLG-240H-C1050AB handle humid or dusty industrial environments?

The series is rated IP65 or IP67 depending on type for dust and water protection, and the working humidity rating is 20-95% RH non-condensing. With a case temperature (Tcase) range of -40°C to +90°C (output derating applies at high ambient temperatures), it suits warehouses, production floors, and covered outdoor industrial areas.

What LED string voltage range is compatible with the HLG-240H-C1050AB?

The CC voltage range is 119-238V. Your LED series string's total forward voltage must fall within this window. The driver automatically regulates its output voltage to deliver a steady 1050mA to the load. The number of LEDs in series depends on each LED's forward voltage.
