Test conditions and notes15
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Please refer to "DRIVING METHODS OF LED MODULE".
  5. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  6. 6. 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.
  7. 7. 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)
  8. 8. 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.
  9. 9. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
  10. 10. 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.
  11. 11. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
  12. 12. 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).
  13. 13. 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
  14. 14. For A/AB type need to consider build in using to comply with Type HL application.
  15. 15. Products sourced from the Americas regions may only have the UL, CE and UKCA logos. Please contact your MEAN WELL sales for more information.

FAQ

Can I use the HLG-185H-24A to power 24V LED strips in a sheltered outdoor area?

Yes. The HLG-185H-24A delivers 24V at up to 7.8A (187.2W), and the series' metal housing with IP65/IP67 ingress protection is designed for indoor and outdoor applications, so it suits installations under eaves, canopies, or covered patios.

Is the adjustable output on the HLG-185H-24A useful for fine-tuning LED brightness?

Yes. The built-in potentiometers let you trim output voltage (22-27V) and current (3.9-7.8A) without an external dimmer. You can reduce the drive level to match a specific LED load or lower brightness. This is helpful when the nominal 24V is slightly more than your LEDs require.

Can the HLG-185H-24A drive 24V LED modules for indoor retail display lighting?

Yes. At 187.2W and 24V, it can power extensive runs of 24V LED modules for display cases, shelf lighting, or backlit panels. The adjustable output lets you match the driver precisely to the LED string voltage, and the wide 90-305VAC input accommodates various commercial mains supplies.

Can I use the HLG-185H-24A for 24V landscape lighting under a porch or awning?

Yes. The series' IP65/IP67-rated metal housing is designed for indoor and outdoor applications, which covers sheltered installations like porch-mounted landscape lights, soffit fixtures, or under-awning accent lighting. Waterproof connectors are available for the output cable.

How many meters of 24V LED strip can the HLG-185H-24A handle?

Divide 187.2W by your strip's wattage per meter. For instance, a strip rated at 10W/m allows about 18.7 meters (187.2W / 10W per meter = 18.7m). Always check your specific strip's rated power per meter and keep total load at or below 187.2W for reliable operation.

Is the HLG-185H-24A suitable for installation in a dusty warehouse environment?

Yes. The IP65/IP67-rated metal housing protects against dust ingress, making it suitable for warehouses, workshops, and other dusty indoor environments. The -40°C to +90°C case temperature range handles unheated buildings, though in hot, poorly ventilated spaces the output load must be derated per the datasheet curve.
