P3-01AC - Power Supply longevity
If anyone had to guess or has hard data, what lifespan is everyone getting with their P3000 power supplies? I am only now starting to record service entry dates on each power supply, but if I had to guess, about 5-6 years is all we get. Anyone else?
I have had one in service for 6 years now.
edit: and to clarify conditions from seeing the comments below, the panel is quite warm and there is no AC. I would say the average panel temp is about 50 degrees C.
Hi @Newbie (Customer),
P3-01AC Operating Design Life 10 years at full load at 40°C ambient and 5 years at 60°C ambient according to the following specification:

Hi Garry, air conditioned factory, inside a cabinet, below 40C. Dunno why in our factory we dont get the longevity like we do with other supplies. Are you using any conditioning on the incoming AC?
Hi @Newbie (Customer),
As a standard practice, we use surge protection on the AC line.
I see AD now sells these devices.

Since you are not getting the life out of the power supplies, I would give AD tech support a call and see if they can't diagnose one of the failed power supplies. This may give you an insight into the cause.

I replaced C5, C7, C12 and C14.
The PSU powers the Base now.
FYI:
[EDIT]
I transposed the specs/measurements for caps 5 and 7.
The above table has been updated.
(There are at least two hardware revs of the PCB with different silks.
There are at least three construction builds. One has bodged-in resistors and capacitors across other component leads.
I did not recognize this when I was making my notes.)
I had my first one die a few weeks back it was around 4 years old and was installed in a room that was 50c-60c all year long.
I had the same die that I replaced in the previous post two months ago I forgot to ask maintenance to keep it for me to test the caps. I also had different one die on me last night. i don't have a date but i would bet it was around 8 years old.
Do the newer one last any longer? the only part to die on me on the productivity series that i did not cause is the P3-01AC. I admit they are not in the best environment but we have AB Logix 5000 and PLC 5 power supplies in the same cabinet i have never had to replace and they are much older.
i don't have a date but i would bet it was around 8 years old.
Can you post the serial number (under the barcode.) It will not indicate in-service time, but it will indicate build date. At one time (I do not remember if it was in this forum or the legacy forum) there was a breakdown of the serial/date code/
ie. the one I have in hand right now is P3-01AC+18Y19F079F
the number is P3-01AC+18109F139E
