We are building machines for export to the USA and need a cost effective solution for the simple machines. The Lexium 28 does have UL approval but most of our customers only have a 460V 3phase industrial supply available. Is there any documentation recommending which transformer can be used to achieve UL approval using the Lexium 28 at 460V 3phase which we can give to our client to accept the Lexium 28. TVDA? We are aware that the Lexium 32 is rated up to 480V 3 phase and we have already shipped our first machine to the USA with the Lexium 32 and BSH motors. However we need a more cost-effective solution as these are only 0.75kW & 1.0kW applications and they are only used to position a section of the machine and then do not move during production.
