Title: need help with psu emerson 1200 Post by: chentron on August 02, 2017, 06:03:14 PM I have 3 psus from old spondoolies sp31. I want to recycle and power on alone for other miner.
I get pinout from web for a emerson 1200, but I am not able to power on. https://www.rcgroups.com/forums/showthread.php?2606324-Astec-DS1200-3-server-power-supply thanks help for getting power on this unit.

That's where I'd start anyway! Good luck!! :) Title: Re: need help with psu emerson 1200 Post by: chentron on August 02, 2017, 06:57:52 PM I found solution.
A1 and B4 pin to ground and power ON ok :) Title: Re: need help with psu emerson 1200 Post by: VRobb on August 02, 2017, 07:03:02 PM Interesting. For future reference to those looking up this thread, A1 is PS_ON, B4 is AC_OK (AC is present).
Nice work, cheers! 8) Title: Re: need help with psu emerson 1200 Post by: chentron on August 02, 2017, 07:46:39 PM to be rigorous:
A1 is PS_ON, B4 is AC_INHIBIT if you measure voltage you will not get nothing till you put something consuming. I used a spare 12v fan to test |
