Frequently asked questions
Is UHP-350-5 rated at 300W or 350W?
The 5V model is rated at 300W and 60A in the specification table. The UHP-350 series name does not mean every voltage version has the same output power.
Does this slim LED power supply have a fan?
No. UHP-350-5 uses free air convection. Follow the datasheet derating curve and provide the required cooling conditions.
Are DC OK and redundancy functions standard?
The datasheet identifies these as options associated with the R version. Do not assume they are included with the standard UHP-350-5.
Where are the dimensions and wiring details?
Download the linked UHP-350 PDF for the mechanical drawing and terminal information. Check the mounting and connection layout before replacing an existing supply.
