Cabinet and cooling requirements
The fanless design transfers heat through its bottom plate. Mount it firmly to the specified aluminum plate or a suitable sign cabinet surface; the original installation guidance calls for a 450 × 450 × 3mm plate. Confirm the exact model on the unit nameplate, the mains supply and the LED module voltage before ordering.
Frequently Asked Questions
What is the difference between HSN-300 A and B models?
A models use 90–132VAC input and have a 50A rated output. B models use 180–264VAC input and have a 60A rated output.
Which HSN-300 model provides 300W?
HSN-300-5B is rated at 5V, 60A and 300W. The other listed versions have the ratings shown in the table.
Can an A model be connected to 230V AC?
No. The stated AC range for an A model is 90–132VAC. Select the B version for a supply within 180–264VAC.
Should I select 4.2V or 5V?
Match the voltage required by the LED module or driver circuit. Do not select only by current rating or cabinet size.
Can the fanless supply be installed without a heat-transfer surface?
Follow the manufacturer’s bottom-plate mounting requirements. Fanless operation still depends on proper heat transfer and derating.
