Output Rating and Version Check
The original listing describes this model as 300W and gives an operating range of -25°C to +70°C. The linked manufacturer specification, version 1.0 dated 2018-08-17, instead states 276W, +4.6V DC and 0–60A at 200–240Vac; its introduction gives -30°C to +70°C. These published values differ. Confirm the supplied unit’s label and applicable specification before deciding the load or operating conditions.
The PDF identifies short-circuit protection (SCP) and overcurrent protection (OCP). Check the specification’s derating curves when evaluating an enclosure or operating temperature.

Frequently Asked Questions
Does the L300V4.6A2 work with a 110V AC supply?
The specified input range is 200–264Vac. A 110V AC supply is outside that range.
Is this model rated at 300W or 276W?
The original listing uses 300W, while the linked version 1.0 manufacturer PDF specifies 276W. Check the unit label and applicable document before sizing a load.
Can it replace a 5V LED power supply?
Do not select it by the similar model name alone. The linked PDF specifies +4.6V DC; compare the LED module requirements, terminal layout and mounting dimensions before replacement.
What protection functions are documented?
The manufacturer PDF lists short-circuit and overcurrent protection. Refer to its protection section for operating conditions.
Where can I download the L300V4.6A2 datasheet?
The original specification PDF is available in the Download Specification section above. It includes electrical data, derating curves and installation information.
