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 power supply 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-480H-C1750AB for dimmable high-bay industrial LED lighting?

Yes. The HLG-480H-C1750AB provides 480W at 1750mA constant current with both output adjustment and external dimming input (0-10V, 10V PWM or resistance). This makes it ideal for warehouse or factory high-bay fixtures where you need to dim lights based on occupancy or daylight harvesting while also fine-tuning the drive current to match your specific LED modules.

Is the HLG-480H-C1750AB a good choice for dimmable LED grow lights?

Yes. At 480W and 1750mA, it supplies enough power for high-output horticultural fixtures. The AB suffix means you can adjust the output current via potentiometer to tune light intensity and dim externally via 0-10V, 10V PWM or resistance to simulate sunrise/sunset cycles or adjust intensity for different growth stages.

Can I use the HLG-480H-C1750AB for dimmable outdoor architectural LED floodlights?

Yes. The 1750mA constant current output across 137-274V suits high-power floodlight arrays for building facades or landscape features. The dimming input allows scene control through a building management system, and the IP65 rating protects the driver in covered outdoor mounting locations.

What dimming methods does the HLG-480H-C1750AB support?

The AB suffix indicates the driver accepts 3-in-1 dimming through an external input: 0-10VDC, a 10V PWM signal (100Hz-3kHz), or resistance. The built-in potentiometer also allows manual adjustment of the output current (875-1750mA). The minimum dimming level is about 6% of the output current.

What LED string voltage range is compatible with the HLG-480H-C1750AB?

The constant current output voltage range is 137-274V. Your series LED string's total forward voltage must fall within this range for the driver to regulate at 1750mA. The exact number of LEDs you can connect depends on each LED's individual forward voltage.

Can the HLG-480H-C1750AB be mounted in a dusty manufacturing environment?

Yes. The IP65 rating means the driver is protected against dust ingress and low-pressure water jets. This suits factories, workshops, and processing plants where airborne particulates and occasional water spray are present. The -40 to +90 degree Celsius case temperature (Tcase) range also handles unheated industrial spaces.
