I can see why you might have difficulty finding such a device. Your specifications are ambiguous. Do you really mean variable frequency or the ability to operate from either 50 or 60 Hz mains. Ditto for variable voltage. 3000VA makes no sense in the context of 120VAC or 230VAC at 16 amps.
It is not clear what commercial benefit such a device would have (except to separate a fool and his money) so I am skeptical you would ever find such a device used.
