Industrial power supplies could be very useful as they usually provide high power, high efficiency and great regulation while you can get them very cheap, the problem is that they usually have special pinouts and it is sometimes difficult to even turn them on. If anybody runs into any of such and discovers their pinouts or other informations, please share!
Lets start with the Astec AA23160 from Cisco 3800 gateway (Cisco PN 341-0090-02), a 300W power supply (23 A/+5 V, 22 A/+12 V; it seems to use independent magamp regulation so you can load only single rail as you wish). I've only discovered how to turn it on so far. The pinout:
Power pins:
||____||___||___|| 14_signal_pins
+12 V GND +5 V
Signal pins:
A1 A2 A3 A4
B1 B2 B3
C1 C2 C3
D1 D2 D3 D4
The +12 V PWR_On is on the C3 (shorter) pin so ground that one (to either of the power GND) and it jumpstarts!
