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-C1400AB for dimmable high-bay LED fixtures in an industrial facility?

Yes. The HLG-240H-C1400AB delivers 1400mA at 250.6W with both an adjustable output and 1-10V/PWM dimming input. This suits high-bay fixtures in factories and warehouses where brightness levels need to adapt to occupancy or daylight conditions. The LED array's forward voltage must total between 89V and 179V.

Is the HLG-240H-C1400AB suitable for dimmable LED area lighting in parking structures?

Yes. At 1400mA and 250.6W, it powers high-output area lights designed for higher drive currents. The dimming input allows integration with motion sensors or time-based controllers to reduce brightness during low-traffic periods. The IP65/IP67-rated series housing and -40°C to +90°C case temperature range (derating applies at high ambient temperatures) handle typical parking structure conditions.

Can the HLG-240H-C1400AB drive dimmable LED signage with scheduled brightness changes?

Yes. The 1400mA constant current output handles large LED sign arrays whose series string voltage falls between 89V and 179V. The 1-10V/PWM dimming input connects to lighting controllers for automated day/night brightness scheduling, and the adjustable output lets you calibrate the drive current to your modules.

What LED string voltage range works with the HLG-240H-C1400AB?

The CC voltage range is 89-179V. configure your LEDs in series so that the sum of their forward voltages falls within this window. The driver maintains a steady 1400mA and adjusts output voltage automatically. The number of LEDs in series depends on each LED's individual forward voltage.

Can the HLG-240H-C1400AB be used in a dusty or humid manufacturing environment?

Yes. 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, making it suitable for manufacturing floors, food processing areas, and other demanding indoor environments. The -40°C to +90°C case temperature range accommodates wide temperature swings, with derating at high ambient temperatures.

What dimming options does the HLG-240H-C1400AB offer beyond the built-in potentiometer?

In addition to the output adjustment potentiometer, the HLG-240H-C1400AB accepts external 1-10V analog and PWM dimming signals. This allows connection to wall dimmers, building management systems, daylight sensors, or motion-triggered controllers for dynamic brightness regulation independent of the static current adjustment.
