KevG's power supply
Posted: Sun Nov 23, 2014 7:25 pm
Well like most I used to run 2 Dps600pb power supplies like most on here, but the way I was using it, I was not using the 24v so I looked else where,
So after looking around I came to the decision to use the DPS 1200 FBA it's a hot plug server power supply and as I am only using 1 it does not need any modification, it's small and compact as well.
So the specs @ 240v input
1200 watts and 100amps on a 12v output,
Here she is,
And what I did to it,
Job 1. Remove server holding mechanism, now you can take the case off and remove the rivets and spring, but I covered the unit ground a grove in the arm as it leaves the case and put a small square of wood in the space to hold the sprung clip up to keep the holders in the case
Job 2. Then it was time to add the bullets for connecting the charger to, simple job of soldering to the hot plug,
Job 3. Make it turn on, you just need to solder a metal film 0.6w 560 ohm resistor between pins 33 and 36 as shown in pic,
But I did a bit more than just solder the resistor, I put in a switch in this line, I just used a few strips of servo wire, then put a small peice of 12 guage silicone wire sheath over the top of the resistor and solder ends to protect it, the switch mount is an old key ring ID tag cut up I wamted the switch on the end but did not want to restrict the air flow,
Just to finish it off a small peice of electrical tape to cover the exposed hot plug,
And the supply in its home case,
