  • TypeAT
  • High efficiency up to 94% reduces energy waste
  • IP67 and IP65 ratings allow indoor and outdoor installation
  • Universal AC input up to 305VAC works worldwide
  • Active PFC function improves power quality

24 V 185 W LED driver

The Mean Well HLG-185H-24A is a single-output switching power supply rated for 24 V at 7.8 A. It targets installers who need a constant-current source for LED lighting or street-lighting projects. The unit accepts a universal AC input up to 305 VAC and delivers up to 185 W with active power-factor correction built in.

IP67 IP65 sealed enclosure

The housing meets both IP67 and IP65 ratings, so it withstands dust, water jets and temporary immersion for indoor or outdoor mounting. Cooling relies on free-air convection with no fan, which keeps silent operation and reduces moving-part wear. Protections cover short circuit, over current, over voltage and over temperature, while 4 kV surge immunity per IEC 61000-4-5 hardens the supply against line transients.

Adjustable output and dimming options

Output voltage and constant-current level can be trimmed via an internal potentiometer on A-Type versions. B-Type units add 3-in-1 dimming through 1–10 VDC, PWM signal or resistance control, giving installers flexible light-level management without extra gear. The series carries a seven-year manufacturer warranty and is rated for Class I Division 2 hazardous-location luminaires.

Questions about this item

What AC input range does the HLG-185H-24A accept?

The HLG-185H-24A accepts universal AC input up to 305VAC, covering full-range mains voltages worldwide.

What are the IP ratings and physical mounting requirements for this power supply?

The A-Type variant is IP65 rated with internal potentiometers; the Blank-Type is IP67 rated with cable I/O. Both are designed for indoor or outdoor LED lighting installations.

How do you adjust the output current on the HLG-185H-24A, and what is the common mistake?

On the A-Type, adjust the constant current level via the internal potentiometer; the common mistake is opening the sealed unit, which voids the IP65/IP67 protection.
