One way would be to pull out the invividual parts of the date part and reorder them to utc? Swap day and month around to required format

DECLARE @date nvarchar(50) = N'02/10/2015 14:26:48'

SELECT CONVERT(datetime, SUBSTRING(@date, 7, 4) + '-' + SUBSTRING(@date, 4, 2) + '-' + SUBSTRING(@date, 1, 2) + ' ' + SUBSTRING(@date, 12, 8))
