Any switch mode power supply manufacturer in Argentina ?

Gentlemen,

I see that quite a few members from Argentina are contributing here.
For somebody in Buenos Aires I am looking for a local manufacturer of
SM power supplies.

The task is to replicate something like a TDK Lambda 28 V 9 A supply of
the DTM250-D series, these are according to regulations for medical use.

The supplier must be able to deliver quantities of the supply and preferably
cheaper than Lambda. Lead time of the TDK factory is about 11..13 weeks.
At the moment it is only possible to order small quantities from the usual
vendors.

I do however not expect that a factory like this exists in South America
(btw is this a common economic area without custom duties ?) but who
knows.

Thank you for useful replies. I do not intend to be bashed, was just asked
for assistance.
