I have some old server power supplies laying around with the intention to convert them in to a good power source for my HAM stuff.
The base will be and DSP-600 from HP, capable of producing 47Amps on 12v.
With some tweaking it can produce 13.8V, Also it has a 5V. Always handy for testing purposes.
What is needed
So here are the basic ingredients:
- 19″inch housing
- HP DSP-600 PSU
- Nice analog Amp meter (up to 50 Amps)
- Nice analog power meters (5 and 13.8 Volts)
- High amp sockets (22 Amps each)
- Voltage regulation circuit capable of at least 10 Amps.
- Good shortage protection on the outputs.
The DSP-600 has a pin out instead of an PCB (like the smaller 36Amps PSU’s)
4—————– (Controls fan speed)
7—————– (not sure what this one does)
9—————– (Voltage Adjust)
11—————- (Current Share)
12—————- (not sure what this one does)
By shorting pins 6 – 8 and 10, the PSU boots when you put in the power cord.
I will add a 1k variable resistor between 3-9 to allow voltage adjustment up to 13.8V, also a NTC between pin 4 and ground to make the fan temperature controlled.
For Amps and voltage meters i want to give it a somewhat antique look.
Of course it will house in a nice 19″ casing.
