The large primary side filter capacitor is normally 400V on switching power supplies in 230V areas. I don't know about that model specifically, but you can see that the power supply on the related DR-MV1S differs between japanese and european model on this
schematic. If you look at the schematic e.g the schematics
for the multisystem Samsung SV-7000W a 400V cap is used on that too, so I don't know if using this MV5S on 230V is safe.
