After having the power supply on my AWSD die, and looking into replacement options, it seemed that a nice 4 output Meanwell might be just the ticket. They make a model that is a bit expensive but has all the output one could wish for in an arcade power supply. The QP-150-3A is about $100 but has 3.3, 5, 12, and -5.
The AWSD is wired for JVS power so I will utilize the 3.3, 5, and 12 volt. The stock AWSD power supply has 3 connectors:
5 conductor JST VH series (AC-N, AC-L, FG)
8 conductor Molex Mini-Fit (12V, GND)
12 conductor Molex Mini-Fit (3.3V, GND, 5V)
I was well on my way to building a wiring harness to take the screw terminals on the Meanwell and adapting to the JST and Molex connectors needed for the cab wiring, and after my mouser order showed up with the power supply and connectors, I started thinking this would work much better as a single PCB.
This board should screw down to the terminals on the Meanwell power supply and provide the JST VH connector for AC power input as well as the 8/12-pin Molex Mini Fit connectors for DC power output.
I have added the mounting holes and solder pads to add an LCD voltage display, https://www.aliexpress.com/i/32840259666.html?spm=2114.12057483.0.0.206f62fepYHKGu
Also a small switch to change between the 3.3 and 5.0 volt rails being displayed. The QP-150-3A has adjustment POTs for 3.3 and for 5.0, so that should help in adjusting the voltages.
I added a round pad terminal for the FG connection in the cab.
The AWSD arcade cabinet has 2 unused conductors in the 12-pin Molex connector. The stock AWSD power supply provides 3.3 volts on these pins that is never utilized inside the AWSD cabinet. I have included a 3-terminal jumper "JP1" on the interface board. It allows selection of 3.3V or -5V for these 2 pins. The rationale is that if you wanted to add the pins and wires to your AWSD arcade cabinet, you could add -5 Volt to the wiring harness and enjoy the games that require -5V. The hardest part would be sourcing the pins for the JAMMA connector, but you might be able to reuse off old harness.
