Values follow the corresponding model columns and A-type option in the linked HLG-240H datasheet. Low input voltage and high case temperature may require output derating.
Choosing between 24V, 36V and 48V
Select the nominal voltage required by the LED load, then check its current, power and operating mode against the matching column. These are separate output models. Built-in adjustment fine-tunes that model’s output; it does not convert one voltage version into another.
Frequently asked questions
What is the difference between HLG-240H-24A, 36A and 48A?
They are rated at 24V/10A/240W, 36V/6.7A/241.2W and 48V/5A/240W respectively. Choose the version that matches the LED load.
Do these A-type models support external 3-in-1 dimming?
No. A-type output voltage and current are adjusted through built-in potentiometers. External 3-in-1 dimming is a different suffix option in the HLG-240H series.
Are these HLG-240H drivers IP65 or IP67?
The three A-type models listed here are IP65. The series also includes other suffix versions with different protection and control options.
Where can I check the adjustment ranges and dimensions?
The comparison table above gives the model-specific ranges. The original PDF below contains the complete electrical ratings, 244.2 × 68 × 38.8mm A-type outline and load curves.
