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. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
8. 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.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
10. 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).
11. 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-185H-C500A to drive a long series string of LED modules for signage?

Yes. The HLG-185H-C500A outputs 500mA constant current with a 200-400V compliance range, allowing very long series strings of LED signage modules. At 200W, it provides substantial power for large sign faces or channel letter arrays. The adjustable output lets you fine-tune current to match the LEDs' optimal drive point.

Is the HLG-185H-C500A suitable for driving long runs of series-connected LED downlights?

Yes. The 200-400V compliance voltage accommodates extended series strings of downlights, each rated for 500mA. This is useful in commercial corridors or open-plan offices where many fixtures are wired in a single series loop. The adjustable output trims current to optimize efficiency and light output.

Can this driver power series-wired LED modules in a large light box or display?

Yes. The 500mA constant-current output at up to 400V compliance voltage can drive a high number of LED modules in series, which is common in large backlit displays and light boxes. At 200W, it handles substantial illumination loads. The series' IP65 or IP67 rating allows installation in damp or dusty environments near the display.

Is the HLG-185H-C500A appropriate for outdoor LED fixture installations?

Yes, in sheltered locations. The series' IP65 or IP67 rating protects against dust and water jets, making it suitable for covered outdoor mounting areas. It is rated for a case temperature (Tcase) of -40°C to +90°C, with derating per the derating curve. Note that this model outputs high voltage (up to 400V), so proper enclosures and safety practices for high-voltage wiring are essential.

How does the HLG-185H-C500A compare to the C700A and C1050A in the same series?

All are adjustable constant-current drivers rated around 200W. The C500A provides 500mA at 200-400V for the longest possible LED series strings. The C700A delivers 700mA at 143-286V, and the C1050A outputs 1050mA at 95-190V for shorter strings with higher-current LEDs. Choose based on your LED modules' required drive current and forward voltage.

How many LEDs can the HLG-185H-C500A drive in series?

That depends on each LED's forward voltage at 500mA. The compliance range is 200-400V, so the total forward voltage of your series string must fall within that window. For example, LEDs with a 3.0V forward voltage could allow roughly 67 to 133 LEDs in series. Always verify your specific LED forward voltage specifications.
