Neo Geo MVS 4-S cabinet move to Europe

[aloux]

Hello, I recently moved to Europe bringing my Us Ne Geo 4-S MVS cabinet.
I switched the PSU from 115V to 230V input but the unit is not working.

I see the screen protection transformer seems to be rated for 115V.

I guess my question is: when switching the input voltage on the PSU from 115V to 230V, will the AC output of the power supply change to 230V as well or will it stay at 115V?

If anyone has experience with moving units from US to Europe (or other 230V countries), would you suggest just getting a power converter and keep the unit 115V or replace components to work on 230V? (the PSU is easy to replace but no idea about the protection transformer...and I assume if the transformer is 115V, probably the screen is rated for the same...

after digging a little more on the isolation transformer, it seems like I may need a step down iso transfomer (230V input, 115V output)...

I guess my question remains for the PSU: is the output following the input on a switchable PSU (115V/230V), in other words, will the AC output remain at 115V if the input is switched to 230V?

this then leads to a different question regarding the CRT monitor: since it was designed to be in the US (115V/60Hz), If I manage to feed it 115V in Europe, the frequency will be 50Hz...Has anyone experienced display issues when running those Us monitors in Europe?

If nobody pops in with an answer here, you may want to post over on KLOV ( https://forums.arcade-museum.com/ ) which is full of original cab owners. Someone there might have the experience you need.

If you switch the PSU input to 230V, you have to power it with 230V ac or it will not work. If you have powered with 240V ac the PSU set to 115V, you have killed it.
It is well likely the case that your cabinet is equipped with a isolation transformer for the monitor. That must be replaced with an iso transformer with 230V input -115V output. The iso transformer must be adeguately dimensioned for the monitor specs ("big enought"). Check your monitor manual.
Generally the PSU is directly connected to the ac line, not the iso. The iso is there for the monitor only.
Monitors for the EU market and USA market are the same: you will have no issues at all.

thanks baritonomarchetto!

the PSU was correctly switched to 230v input and powered with 230V but as soon as I turned the cabinet on, the PSU circuit breaker tripped.
I will check the AC output from the PSU to see if it just steps down the output to 115 or just provides 230V as the input.

thanks for the explanation!

thanks for the tip meyer980

That "AC output" you speak of makes no sense to me. With "PSU" I mean the switching power supply. That component is  alternate current powered (115 or 230V AC, generally you can set it with a DIP switch) and outputs the game board requited non alternating voltages (+5V for logic, +12 for amplified and, on some older game boards, also -5 was used for amps).
The isolation transformer is instead a passive wiring that isolate everithing wired after that from the wall tension. It "converts" the  wall, alternate voltage to another (or the same) alternate voltage.

I may be expressing myself confusingly, sorry about that.

the PSU in the cabinet is indeed AC 115V/230V input.
this PSU has indeed a DC - +5V 15A, +12V 5.5A, -5V 1A. 
it also has an AC output to feeds the isolation transformer

here's the PSU in question: https://na.suzohapp.com/products/power_supplies/80-0072-00

The one thing I have not been able to find out is by switching the input of the PSU from 115V to 230V if the PSU AC output remains at 115V or follows the input.
I was trying to find the information online but instead will get a voltmeter and check the output directly
