PAIA 9700 Addition (Part 2)

The next task was to construct the power supply. In the picture you can see all the parts that PAIA supplies in the kit. On the top right you can see the alternative front panel that is provided with holes for the leds and power switch. On the left is the PCB. This PCB is used for all the power supply variations that PAIA supplies. So you have to see in the manual which components to install and which you don't. There is also a jumper on the PCB that you need to mount. I almost forgot it. So pay attention :)

Here you see the front panel installed in the 19 inch cabinet. There is a power led that shows if the external power is there and also two leds for the +15V and -15V outputs from the power supply. I think PAIA came up with a very neat solution for it in this way. It doesn't take up any extra space in the cabinet and you can still mount 10 Frac units in the case. It is a bit fiddling around though to get the leds on the right length on the PCB so that they just stick out of the holes of the front panel.

 And here you can see the finished PCB on the inside of  the cabinet. Also a bit of fiddling to get it in. The holes are already in the side of the cabinet to mount it by the way. Just make sure you have the side panels with the holes to the front. I still need to hook up the power from the external adapter, but wanted to make sure it fits. The only thing that is a bit odd is that when you need to hook up an module, you need to take the PSU out again to solder the wires for the power of the module on the PCB. On the other side (on the module itself) PAIA uses a connector. I think they should have done the same on the power supply itself. That would have made it a bit more flexible. Ah well. It will work in the end I guess.
