Flexmod Fault Problem

[Mlenox]

Hey Ya'll...


It seems like My flexmod does't like to stay on for very long. Interlock is intact. Diode loop is intact. Re-setting power to it seems to fix it temporarily. I have a huge heatsink on it, yet it happening over a period of time leads me to believe that it's heat related. I dunno. I've tried everything. Any ideas?


EDIT: It might be because I don't have a unified ground. I'll re-wire it tomorrow and see what happens...

what power supply are you using? i was using a 5v PSU and had the same problem. i now use the 12v rail and it works great

Are you sure the current actually stops running, and cooling of the diode is sufficient ?

I remember reports of 445 diodes stopping remitting light when overloaded, then miraculously coming back to life after a reset.

I had a FMP3 that started showing the red led, turned out it was an early warning sign the PSU was dying.
