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-C500AB for dimmable long-string LED signage installations?

Yes. The HLG-185H-C500AB provides 500mA constant current with a 200-400V compliance range, supporting very long series chains of LED signage modules. The AB model includes both output adjustment and 1-10V/PWM dimming, enabling day/night brightness scheduling through a lighting controller.

Is the HLG-185H-C500AB suitable for driving series-connected LED fixtures in a commercial corridor with dimming?

Yes. The 200-400V compliance range allows many LED fixtures to be wired in a single series string, reducing wiring complexity. At 200W and 500mA, it handles long runs of corridor downlights or linear fixtures. The dimming input integrates with building management systems for occupancy or daylight-responsive dimming.

Can this driver power a dimmable backlit LED display or light wall?

Yes. The high compliance voltage of 200-400V accommodates large arrays of series-wired LED modules typical in backlit displays. The 500mA constant-current output keeps brightness uniform across the array, and the dimming interface allows content-synchronized brightness changes or energy-saving schedules.

What safety considerations apply when using the HLG-185H-C500AB outdoors?

The series' IP65 or IP67 rating protects against dust and water jets, making it suitable for sheltered outdoor installations. However, the output can reach 400V DC, which requires proper high-voltage wiring practices, insulated connectors, and code-compliant enclosures. The case temperature (Tcase) must stay within -40°C to +90°C, with derating per the derating curve.

How does the HLG-185H-C500AB differ from the C500A and C500B?

All three share the same 200W, 500mA, 200-400V constant-current specs. The C500A has only an output adjustment potentiometer for current trimming. The C500B has only a dimming input (1-10V/PWM). The C500AB combines both, providing manual current adjustment plus external dimming control.

How do I verify that the HLG-185H-C500AB is compatible with my LED configuration?

Confirm that your LED modules are rated for 500mA drive current, then calculate the total forward voltage of all modules wired in series. The sum must fall between 200V and 400V. The number of LEDs you can connect depends on each LED's forward voltage at 500mA. Also ensure total power does not exceed 200W.
