Using the driver with a 12V LED load
Confirm that the LED equipment requires 12V and stays within the rated current and power. For constant-current operation, check the load voltage against the 6–12V region. A display or lighting product’s voltage requirement must be checked before connecting it; the driver is not suitable for every LED screen merely because it is an LED power supply.
Frequently asked questions
Does “12A” in HLG-150H-12A mean 12 amps?
No. The model code combines a 12V output designation with the A function suffix. The specified rated output current is 12.5A.
Can I adjust the HLG-150H-12A output?
Yes. The built-in voltage adjustment range is 10.8–13.5V, and the current adjustment range is 7.5–12.5A. Follow the connected load’s permitted settings.
Does HLG-150H-12A include external dimming?
This A-type model has built-in adjustment. External 3-in-1 dimming is offered on different suffix versions in the HLG-150H series.
Is this model IP65 or IP67?
HLG-150H-12A is the IP65 version. The retained PDF provides the suffix-specific function table, mechanical drawing and operating curves.
