100V ac Roland XV-3080

[Jackie The Shepherd]

I just bought a used Roland XV-3080 at reverb.com after the seller confirmed he has checked the operation again for me and confirmed all okay. The machine came with 100V ac 50/60 Hz printed. Suddenly I realised that the seller being located in Bahrain, which has 230V ac just like us in India, how could he have tested on 240V.

I sent him a text this morning and here below is his reply:

Hello Nader,

Good morning and a very happy New Year 2026.

I have received the package in excellent condition. Thank you for the packing and everything.

One thing I saw was the voltage on the back as 100V instead of 230V, which is what we have in India and I think in Bahrain too. So how did you manage to check operation of the device at your place? If you can advise me, I will look for a suitable adaptor.

Regards

Hi Sumit,

Happy new year to you.
The voltage is universal, works on 100 to 240v. You don't need any voltage converters.

Best regards
Nader

Okay but I am being told that I cannot and should not plug this into a 230V socket as the capacitors will be weakened.
I hope you didn't run it for long when testing.

That's not correct, the unit is fully capable of running on any voltage.
I have used it for many years on 240v without any issues.
The unit has internal switching and can be used anywhere in the world.

While I am going to get a voltage converter for myself, I am not sure how much damage he would have already done to the equipment and not sure how he can make such a claim.

There are hints that this uses a switch-mode power supply, and if so I'd be very surprised if it's not a universal PSU, but if in doubt why not contact Roland and ask them?

[Jackie The Shepherd]

Well, my concern stems from the Roland label behind which clearly states:

AC 100V, 50/60 Hz, 13W.

Would then you still feel it could be a universal PS?

[Wonks]

From what other people have written about this and other similar Roland modules, yes.

The voltage rating on the back is an indication of the market it was sold into. 100v was the Japanese market version.

It helped Roland tell if there were unofficial 'grey' imports into other countries as they had a different pricing policy for different areas of the World.

It seems Roland did label the units in this misleading way. The service manual confirms it is a universal switching PSU so it will work safely on any mains voltage.

[James Perrett]

The service manual doesn't include any information about the power supply apart from a part number. The same power supply part number seems to apply to all versions so it is almost certainly universal.

[Tomás Mulcahy]

While the manual is not super specific, there are clues and tidbits of info:
Under specifications:
"Power supply AC117, 230, 240 V"
Accessories: Separate AC cord sets per voltage implies global compatibility via cabling only.
And as james pointed out, only PSU part is listed, implying it is the same for all regions. It is described as a switching regulator.

[Tomás Mulcahy]

Edit: a100V cord is listed as an accessory.

[Jackie The Shepherd]

That bit about "Power supply AC117, 230, 240 V" is there even in the online user manual. But since I bought it from reverb.com I checked with the seller, he responded just now like here:

Further talk with Nader:

By any chance, as a technical user, did you at all swap the internal transformer for a 230V version? I am asking because if it is so, and I apply 100V, it's going to be another problem.

Not at all, I bought it few years ago from a Japanese seller on Ebay. Hence I asked him the very same question regarding the voltage and he informed me that the fully capable to be used anywhere in the world.
Going back to your question, no issues didn't change anything in the unit.

They don't mention the PCB model number. But I do see this power supply module F9262PA B034A being sold on eBay as this one:

Roland VS-/SC-8850/FANTOM XR/XV-3080/DA-2496/VariOS (F9086PA B034/F9262PA B034A)

https://www.ebay.com/itm/297432835058

In fact I just ended up opening the box to check the PS module. Though there were no voltage marking, I noticed the large brown filter capacitor is rated 400V 56 µF.

The only difference I would have thought a 100V Japanese unit might have is no earth connection, whereas ones for elsewhere might. Japanese don't use earthing for devices like we do and on the devices, like washing machines, that do the earth is connected to a wire terminal with the plug being a standard two pin variety.
