Abnormal psu output

Alexandr_P — Tue, 25 Apr 2017 17:24:00 GMT

Hi, all! I have output: PowerSupply 1 information: State : Powered On PartInfo : Internal PSU-1 1424W-81247 800463-00-04 Output 1 : 12.08 V, 2.65 A (12V/200W Max) Power Usage : 43.85 W PowerSupply 2 information: State : Powered On PartInfo : Internal PSU-2 1424W-81246 800463-00-04 Output 1 : 12.04 V, 3.80 A (12V/200W Max) Power Usage : 62.67 W System Power Usage : 106.52 W Poll Interval : 60 s Change Threshold : N/A Change Action : N/A Based on 800463 - it's 550W DC FB PSU. So why this 550W PSU show Max power 200W? Switch X670-48x Thank you!

Hello Alexandr,

I am checking in the lab to see if I see the same behavior.

Hi, Patrick! Write from phone - can't find your answer about Summit 550 watt AC PSU BF 800460-00. It's little different PSU. Thank you!

Hello Alexandr,

The output I am getting is below:

PowerSupply 1 information: State : Powered On
PartInfo : Internal PSU-1 1235W-80911 800460-00-04
Output 1 : 12.02 V, 8.65 A (12V/550W Max)
Power Usage : 131.61 W

I can't explain why you are receiving a different output. Unless it does have something to do with AC/DC. Let me do some more research.

550W is for 220Vac
200W is for 12Vdc
Do you know Ohm's law?

Hi, Nick! Lets remember together. Data sheet: Psu 550W dc - 12V, 45A 12*45=540W. Where you find 200W? Thank you!
