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-C1750A for high-power LED street lighting?

Yes. The HLG-480H-C1750A delivers 480W at 1750mA constant current with a CC voltage range of 137-274V, making it suitable for municipal street light fixtures using high-power LED modules. The IP65 water-resistant rating and -40 to +90 degree Celsius case temperature (Tcase) range handle year-round outdoor conditions in sheltered pole-top housings.

Is the HLG-480H-C1750A appropriate for driving LED grow lights in greenhouses?

Yes. At 480W and 1750mA, this driver has enough capacity for high-output horticultural LED fixtures. The adjustable output (A suffix) lets you fine-tune the current via the built-in potentiometer to match your specific LED module requirements. The wide 90-305VAC input handles varying mains voltages found in agricultural facilities.

Can the HLG-480H-C1750A power LED arrays in large-format stadium or arena signage?

Yes. The 1750mA constant current output across a 137-274V range can drive extended series strings of high-power LEDs used in stadium displays and large advertising signs. The IP65 protection suits installations in covered outdoor concourses or equipment rooms adjacent to the sign location.

Can I adjust the output current on the HLG-480H-C1750A?

Yes. The A suffix indicates a built-in potentiometer that allows you to adjust the output current. This is useful when you need to fine-tune the drive current to match your specific LED module's optimal operating point or to reduce output for thermal management in enclosed fixtures.

How do I determine if my LED string voltage falls within the HLG-480H-C1750A range?

Add up the forward voltages of all LEDs in your series string. The total must fall between 137V and 274V for the driver to regulate properly at 1750mA. Outside this window the driver is not specified to deliver its rated constant current, so size the string to stay within 137-274V.

Can the HLG-480H-C1750A operate in cold climates or freezing conditions?

Yes. It is rated for a case temperature (Tcase) of -40 to +90 degrees Celsius, so it handles extreme cold environments such as northern-latitude street lighting, cold-storage facility exteriors, or unheated industrial buildings. The IP65 enclosure also protects against snow and ice melt exposure.
