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-C1750AB to drive a high-power LED troffer fixture with dimming?

Yes. The HLG-240H-C1750AB delivers 1750mA constant current across a 71-143V CC voltage range (up to 250.25W) and includes both output adjustment and a 1-10V/PWM dimming input. This makes it a strong fit for commercial troffer or panel fixtures where you need both initial current tuning and ongoing brightness control from a building automation system.

Is the HLG-240H-C1750AB suitable for a dimmable LED grow light setup?

Yes. At 1750mA and 250.25W, it can power a substantial grow light array with a series string voltage between 71V and 143V. The AB variant gives you a potentiometer for base current adjustment plus a remote dimming input, so you can set a maximum intensity and then dim remotely during different photoperiod stages.

Can the HLG-240H-C1750AB power dimmable LED high-bay fixtures in a warehouse?

Yes, provided the LED module string voltage falls within 71-143V at 1750mA. At 250.25W it has enough capacity for high-bay fixtures. The dimming input lets you integrate with occupancy sensors or daylight harvesting controllers. The IP65/IP67-rated series housing handles the dust and occasional moisture common in warehouse environments.

What dimming and adjustment options does the HLG-240H-C1750AB offer?

The AB suffix means it includes both a built-in potentiometer for output current adjustment and a 1-10V/PWM dimming input for remote brightness control. You can use the potentiometer to set the maximum drive current at or below 1750mA, then use the dimming input for day-to-day brightness changes from a wall dimmer or automation controller.

Can the HLG-240H-C1750AB operate in a cold outdoor environment like a parking structure?

Yes. It operates over a case temperature (Tcase) range of -40°C to +90°C, so it handles freezing winter conditions, with output derating at high ambient temperatures. The series is rated IP65 or IP67 depending on type for protection against rain and dust. A covered parking structure is a suitable installation environment for this driver.
