JPS300P-D power supply for LED screens
The G-Energy JPS300P-D is a +5.0V DC LED screen power supply listed at 300W total output power. It uses resonant and synchronous rectification circuitry and includes output overvoltage, overcurrent and short-circuit protection. Natural cooling requires contact with a metal backplate for auxiliary heat dissipation.

Input and load conditions: The listing contains two input entries and two current ranges. Do not assume the higher output is available throughout the input range. The linked PDF also contains differing output-current entries in its specification sections; confirm the supplied revision and its input/load limits before selecting the operating current.
Cooling and replacement checks
Check the existing unit’s model, output requirements, input voltage, terminal arrangement and mounting dimensions. Follow the supplied documentation for backplate contact and temperature derating. Contact us with the label and required operating conditions if you need to confirm a replacement.

Frequently Asked Questions
What is the output voltage of the JPS300P-D?
The listed output voltage is +5.0V DC, with total output power listed as 300W. Available output depends on the applicable input and thermal conditions.
Is 60A available at every input voltage?
Do not assume so. The listing gives 0–50A and 0–60A ranges, and the specification distinguishes input/load conditions. Confirm the rating for the supplied revision and your actual AC input.
Does natural cooling mean no metal backplate is needed?
No. The original specification requires installation on a metal backplate to assist heat dissipation during operation.
What working and storage temperatures are listed?
Working and ambient temperatures are −30°C to 60°C, with 25°C typical. Storage is listed as −40°C to 85°C, also with 25°C typical. Observe the stated cooling and derating conditions.
Where is the JPS300P-D specification PDF?
The original download link is retained above. The PDF is marked V1.0, dated 2016/10/11. Its differing current entries should be checked against the supplied unit before using them for load selection.
