Input Transient Protection
A VDR together with the input fuse and a symmetrical input
filter form an effective protection against high input tran-
sient voltages.
Electrical Output Data
General Conditions
–
TA = 25°C, unless TC is specified.
– Pin 18 (i) connected to pin 14 (S–/Vo1–),
Uo adjusted to Uo nom (option P), R input not connected.
– Sense line pin 12 (S+) and pin 14 (S–) connected to pin 4 (Vo+) and pin 8 (Vo–) respectively.

1 If the output voltages are increased above Uo nom through R-input control, option P setting, remote sensing or option T, the output cur-
rents should be reduced accordingly so that
Po nom is not exceeded.
