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-C1750A to power high-output LED downlights?

Yes. The HLG-240H-C1750A provides a constant 1750mA with a CC voltage range of 71-143V, delivering up to 250.25W. It can drive high-output LED downlight modules wired in series as long as their combined forward voltage falls between 71V and 143V. The adjustable output potentiometer lets you reduce the drive current to fine-tune brightness.

Is the HLG-240H-C1750A a good choice for driving LED modules in an indoor signage array?

Yes. At 1750mA and up to 250.25W, this driver handles high-brightness signage modules comfortably. The CC voltage range of 71-143V accommodates various series string configurations. Since it is a constant-current driver, it maintains consistent brightness across the LED string regardless of minor voltage variations.

Can the HLG-240H-C1750A drive LED grow light arrays?

Yes, provided the LED array's total forward voltage falls within 71-143V at 1750mA. At 250.25W, this driver has enough capacity for a sizeable grow light panel. The adjustable output current is useful for tuning light intensity to different growth stages. Note the working humidity rating is 20-95% RH non-condensing, so protect it from condensation and direct water spray in a greenhouse.

How do I adjust the output current on the HLG-240H-C1750A?

The A suffix means it includes a built-in potentiometer for output current adjustment. You can turn the potentiometer to reduce the drive current below the rated 1750mA, which lowers LED brightness. This variant does not include a remote dimming input, so adjustment must be done manually at the driver. For remote dimming, consider the -C1750AB or -C1750B.

Can the HLG-240H-C1750A be installed in a damp warehouse ceiling space?

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. A damp ceiling plenum or warehouse is suitable provided condensation is avoided; the case temperature must stay within -40°C to +90°C, with output derating at high ambient temperatures.

What are the differences between the HLG-240H constant-current variants at the 250W level?

The HLG-240H-C series at approximately 250W comes in several current ratings: C700 (700mA, 178-357V), C1050 (1050mA, 119-238V), C1400 (1400mA, 89-179V), C1750 (1750mA, 71-143V), and C2100 (2100mA, 59-119V). All share the same 244.2 x 68 x 38.8mm case. The choice depends on your LED string's forward voltage and required drive current.
