Test conditions and notes10

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

FAQ

Can I use the HLG-240H-C1750B for a dimmable commercial LED downlight installation?

Yes. The HLG-240H-C1750B delivers 1750mA constant current across a 71-143V range, up to 250.25W. The B suffix provides a 1-10V/PWM dimming input, making it compatible with commercial dimming systems and building management controllers. It can drive high-power downlight modules in series as long as total forward voltage stays within 71-143V.

Is the HLG-240H-C1750B a good fit for dimmable LED flood lights on a building facade?

Yes, provided the flood light's LED array requires approximately 1750mA and has a forward voltage within 71-143V. The series is rated IP65 or IP67 depending on type, and the dimming input allows scene control for architectural lighting effects. For fully exposed installations, check the rating of your type and follow MEAN WELL's IP installation cautions in the user manual.

Can the HLG-240H-C1750B power a high-output LED panel light with dimming?

Yes. At 1750mA and up to 250.25W, it can drive large LED panel lights or troffers. The B variant's 1-10V/PWM dimming input integrates with standard commercial dimming controls. Note this variant does not include an output adjustment potentiometer, so the drive current is fixed at 1750mA before dimming attenuation.

How many LEDs can I run in series with the HLG-240H-C1750B?

The number depends on each LED's forward voltage at 1750mA. The CC voltage range is 71-143V, so you need enough LEDs in series to total at least 71V and no more than 143V. For instance, with LEDs that each drop about 35V at 1750mA, you could run 3 or 4 in series (105-140V). Always verify forward voltages from your LED datasheet.

Can the HLG-240H-C1750B be used inside a sealed outdoor luminaire enclosure?

Yes. The series is rated IP65 or IP67 depending on type, protecting against dust and water. When mounted inside a sealed luminaire, ensure adequate thermal management since the driver generates heat at its 250.25W capacity: the case temperature (Tcase) must stay within -40°C to +90°C, and output derating applies at high ambient temperatures.
