I am looking at various power supplies and see difference in the temp operation range. The upper range is well within my temp extreme but what happens to these at the lower temp limits? (12vdc @ 50w)
More off the hat stuff. http://us.tdk-lambda.com/lp/ftp/Specs/ls.pdf If you really need 5 A, then I would choose a 10 A supply. This Lambda series appears to be rated for operation to -25 C.
