Step up/down Transformer advice wanted (APM3)

Question about step up/down transformers suitable for the SEGA P-ras MULTI 3/APM3 (with the ALLS PC inside):

In Denmark we use 230V/50Hz.
In Japan they use 100V/50Hz or 60Hz.

Volts: Is 110V fine or is it better/a must to have 100V?
Watts/VA: How many watts does it have to be to support the P-ras/ALLS combo?
Noise: And are some transformers more silent than others?

Any specific transformer brands/models you can recommend?

(Someone recommended me Airlink transformers - they are 100V and look perfect, but since the company is UK based it will become rather expensive to import).

Any P-ras 3 owners here that know exactly how many Watts/VA this cab needs?

The APM3 cabinet consumption is 234W, 3,26A at 100V.

I would also recommend Airlink transformers, despite of their price.
In the past, we used both Bronson and US Tronic transformers and several of them failed. While we have an Airlink transformer running 7/7 for years without any trouble.

Using a 110v transformer would work, but I would really advise using a proper 100v one as I think that it could affect the durability of the components in the long run.

Thank you Nomax for looking into this. And for giving me a very precise and concrete answer on the consumption. Much appreciated.

Looks like I will just have bite the bullet on an Airlink... Even though importing one to Denmark more than doubles the price. A 872 DKK (99 GBP) transformer magically turns into 1796 DKK (205 GBP) before it arrives here - Yikes!. Brexit, man...

Yes, brexit is a lose/lose situation in many cases. And especially for the amusement industry.
