I've got a 2kw power supply from a server, I'm trying to repurpose it to power an induction heater. I've been informed that it won't power up unless it sees certain conditions; namely voltage on some of the pins.
Now the question is which pins need to be bridged?

Here is the pdf with the pinouts:

I don't want to go giving 48v to just anything in the hope of trial and error as I'm scared of frying it!
 
Ive been doing a bit of testing today. Ive managed to power it up, but the fault light stays on.
So further probing reveals that if I link LOGIC GND and PS Type ID0 (pins 21 and 8 respectively) the fault light goes off and the AC OK and DC OK lights come on. However, there is no output on 48v.
Any suggestions?
 
I'm going to keyword this a bit so that others may find it.

Martek PS2328 48V Power Supply (Server Power Supply) Bench Conversion follows:

I know it has been a long long time since you posted this but I ran across your thread while trying to solve the same issue. I have the same Martek power supply. After a few hours of head-scratching, I finally got it going.

Plug it in, Join Pin 24 (PS Kill) to Pin 21 (Logic GND), Join Pin 18 (Remote On/Off) to Pin 11 (Relay Control). She'll fire right up. I used female/female breadboard jumpers then tore into the unit, clipped stuff, added switches, etc.. You can do it with it powered on or de-energized. It doesn't seem to matter. I hope this helps you and others who are working with these power supplies.
