MEAN WELL HLG-150H-36A / HLG-150H-48A LED Drivers
The MEAN WELL HLG-150H-36A and HLG-150H-48A are separate 36V and 48V LED driver options with internal output adjustment. Both use constant-voltage and constant-current operating modes in a fanless metal housing, with model-specific power and current ratings.

Frequently asked questions
1. What is the difference between HLG-150H-36A and 48A?
The 36A model is rated at 36V, 4.2A and 151.2W. The 48A model is rated at 48V, 3.2A and 153.6W.
2. Does A mean the driver supports an external dimmer?
A identifies internal potentiometer adjustment. For an external 3-in-1 dimming signal, choose and verify the appropriate suffix version.
3. Can I use the 48A version as a general 24V supply?
Its nominal output is 48V. The 24–48V constant-current region describes LED-driving operation and should not be treated as a general 24V voltage setting.
4. What should I check for an outdoor installation?
These A versions are IP65. Confirm the installation instructions, protect cable connections and keep the measured case temperature within the allowed load conditions.
