7.3 Electrical data
The following tables contain the data which is relevant for UL.
Details of the UL/cUL approval conditions can be found in Section 1.7. Use of mains fuses which are
faster than those stated is permissible.
By the use of a mains choke, the input current is reduced to approximately that of the output current
( Section 2.7.1 "Mains chokes").
