Frequently asked questions
1. How do the 24A, 36A and 48A versions differ?
Their nominal outputs are 24V 7.8A, 36V 5.2A and 48V 3.9A respectively. All three listed versions are rated at 187.2W.
2. Can one HLG-185H unit switch between 24V, 36V and 48V?
No. These are separate voltage models. Select the version that matches the load instead of treating the model list as selectable output modes.
3. What does the A suffix provide?
It identifies the version with internal voltage and current adjustment and an IP65 enclosure. External 3-in-1 dimming belongs to other suffix options.
4. How do I check LED-string compatibility?
Compare the string’s operating voltage and required current with the selected model’s constant-current region and adjustment limits. Also apply the input and case-temperature derating requirements in the PDF.
