Choosing the correct version
The A-300FAY-4.5 and A-300FAY-5 are separate output versions. The 4.5V model is rated at 270W, while the 5V model is rated at 300W. Match the complete model number when replacing an existing supply. Allow for the manufacturer’s load margin and temperature derating rather than selecting solely by the wattage in the series name.

Frequently asked questions
What is the output of the CZCL A-300FAY-4.5?
The rated output is 4.5V DC, 60A and 270W. These values apply to the A-300FAY-4.5 column in the series datasheet.
Can I use the A-300FAY-4.5 on 110V AC?
The specification supplied on this page lists 180–264VAC input. It does not establish compatibility with 110V AC; check the unit label before connecting power.
Is A-300FAY-4.5 the same as A-300FAY-5?
No. They share a series name but have different rated output voltages and power. Select the version required by your LED modules.
Does this power supply include overload protection?
The datasheet lists overload and short-circuit protection. Consult the full specification for protection behavior and operating conditions.
Where can I download the A-300FAY-4.5 datasheet?
Use the Download Specification link above. The PDF includes both output versions, the temperature derating curve and installation drawings.
