Frequently Asked Questions
What output voltage and current does the JPS300V provide?
The rated output is +5.0V DC, with a specified current range of 0–60.0A and an output power rating of 300W.
Does it support 110V and 220V AC input?
The specification lists 110/220Vac (±20%) and a 47–63Hz input frequency. Check the supplied unit’s input arrangement and the PDF instructions before applying power.
What should I check when replacing a JPS300V?
Check the complete model, output voltage and current requirements, input arrangement, terminals, mounting dimensions and cooling requirements. Matching the wattage alone is insufficient.
Is the power factor the same as efficiency?
No. The specified efficiency is ≥78.0%, while the power factor is ≥0.45. These are different measurements; see the table notes and PDF for their test conditions.
Where can I download the JPS300V datasheet?
Use the specification PDF link above. The linked manufacturer document is identified as JPS300V, version V1.0, dated 2018/08/05. Confirm that it matches the supplied hardware revision.
