Little red LED on Hantarex US250 PSU

[ssjenkins]

Hi All,
 I've just noticed that this little LED is illuminated on my PSU . It's situated right under the main O/P connector . I'm not sure if it's always been on as it's difficult to see on my machine . Does anyone know what it indicates ??
Thanks in advance.

You probably want to be posting in the Monitor/Video forum.

Is US250 the monitor model or the PSU model?

Hi ,

 I wasn't sure where to post this question as the PSU doesn't power my monitor . Anyway , US250 is the Hantarex model number .

 Cheers

Hey, I've recently repaired my Hantarex US250 (which was damaged by a failing fan by the way, so not the hantarex's fault) and this LED is simply an indicator that the supply is on. To be more precise: it is driven by the 5V stage of the power supply, so if this is lit, you know the 5V is (about !) good.

For more info about the Hantarex US250 (including schematics etc.) look at this thread:

The 6th posting has the files attached.

Let me know if you need more info on this power supply, by repairing it I learned quite a bit about it.
