The following tables contain the data which is relevant for UL
Details of UL- / CSA approval conditions can be found in Section "UL and CSA approval". Use of
mains fuses which are faster than those stated is permissible.
By use of a mains choke, the input current is reduced to approximately the value of the output current
(Chap. 2.4.1.1 "Mains choke SK CI5").
