Mean Well HLG-150H-12A LED Driver
The HLG-150H-12A supplies compatible 12V LED lighting systems with constant voltage and constant current operation. Its A suffix identifies the version with output adjustment through built-in potentiometers. Check the complete model when replacing a driver: the suffix determines adjustment and dimming features.

Values are from the linked HLG-150H specification. Follow its input-voltage and temperature derating curves when sizing the load.
Choosing the correct driver
Match the LED load voltage, required current, operating mode and installation space before ordering. A 12V driver is not a substitute for a 5V LED-module power supply. Confirm whether your installation needs local adjustment or external dimming.
Frequently Asked Questions
Does “12A” mean a 12-amp output?
No. In HLG-150H-12A, 12 identifies the 12V version and A identifies the adjustable model. Its rated output current is 12.5A.
Is this model dimmable with a 1–10V signal?
The A type uses built-in potentiometers. The datasheet assigns external 3-in-1 dimming to B and AB versions; do not assume those functions are present on this A model.
Is the HLG-150H-12A IP67?
The datasheet specifies IP65 for the A version. IP67 descriptions apply to other versions in the series.
Can it power a 5V LED display module?
Do not connect a load requiring 5V to this 12V model. Select a supply that matches the module specification.
Where can I find the dimensions and wiring information?
