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-C1750B for dimmable LED street lighting projects?
Yes. The HLG-480H-C1750B delivers 480W at 1750mA constant current with a built-in dimming input (0-10V, 10V PWM or resistance). This supports midnight dimming and adaptive lighting programs commonly used in municipal street lighting to reduce energy consumption during low-traffic hours. The IP65 rating protects the driver inside pole-top housings.
Is the HLG-480H-C1750B suitable for large commercial LED panel ceiling installations with dimming?
Yes. At 480W and 1750mA, it can drive high-power LED panel arrays in commercial ceilings, lobbies, or atriums. The B suffix provides external dimming via 0-10V, 10V PWM or resistance, which integrates with building management systems for daylight-responsive or scheduled brightness control.
Can the HLG-480H-C1750B power dimmable LED modules in large illuminated signage?
Yes. The 1750mA constant current output with a voltage range of 137-274V can drive long series strings of high-power sign LEDs. The dimming input allows automated brightness scheduling, such as reducing sign intensity after business hours or dimming in response to ambient light sensors.
What is the CC voltage range of the HLG-480H-C1750B and how does it affect LED compatibility?
The constant current regulation range is 137-274V. Your total series LED string voltage must fall within this window for the driver to maintain a steady 1750mA. The number of LEDs you can connect depends on each LED's forward voltage. If the string voltage falls outside this range, the driver is not specified to regulate current properly.
Can the HLG-480H-C1750B handle high-temperature environments near LED fixtures?
Yes, within limits. Its working case temperature (Tcase) range is -40 to +90 degrees Celsius, with output load derating at higher temperatures per the sheet's load vs temperature curve, so it can be mounted near heat-generating LED fixtures as long as the tc point stays within limits. Typical life of >62,000 hours applies at a tc of about 75°C or less.
What is the difference between the HLG-480H-C1750A, C1750AB, and C1750B?
All three share the same 480W / 1750mA core specs with a CC voltage range of 137-274V and at least an IP65 rating. The C1750A has output adjustment via built-in potentiometer but no dimming input. The C1750AB offers both potentiometer adjustment and external 0-10V/10V PWM/resistance dimming. The C1750B provides external dimming input only without the adjustment potentiometer.
