A 2:1 range of input voltage is common for power bricks.

On page 5-4, the Z3801A manual says:
  BTS  27 nominal  19-30 operating, over 23 starting
  BSC  54 nominal  37-60 operating, over 46 starting

A couple of other places in the manual say 19.5 and 38.  One is a picture of 
the sticker on the back next to the connector.

It would be interesting to see the fine print on the specs for the bricks 
used in the Z3801A.  I expect the oven startup current exceeds the nominal 
value on the brick over the full input range.
