Input Under-/Overvoltage Lock-out
If the input voltage remains below approx. 65 V AC or ex-
ceeds approx. 280 V AC an internally generated inhibit sig-
nal disables the output(s). When checking this function the
absolute maximum input voltage rating U
i abs
should be
considered! Between U
i min
and the undervoltage lock-out
level the output voltage may be below the value defined in
table: Output data (see: Technical Information: Measuring
and Testing).
Input Transient Protection
A VDR together with the input fuse and a symmetrical input
fi
lter form an effective protection against high input tran-
sient voltages.
Input Fuse
A fuse mounted inside the converter protects the module
against severe defects. (If operated from a DC-source this
fuse may not fully protect the module when the input volt-
age exceeds 200 V DC! In applications where the convert-
ers operate at source voltages above 200 V DC an external
fuse or a circuit breaker at system level should be installed!)

Valid for -7 versions with NTC, (-9 versions exclude the NTC). Initial switch-on cycle. Subsequent switch-on/off cycles increase the in-
rush current peak value.

AC frequency range 47...63 Hz.

For DC-input please ask your local Power-One partner.
Reverse Polarity Protection
Should the input voltage to the unit be supplied from a DC
source the built-in bridge recti
fi
er provides reverse polarity
protection. (For DC-input operation, please consult your lo-
cal Power-One partner.)
Inrush Current Limitation
The modules of the versions -7, incorporate an NTC resis-
tor in the input circuitry which
–
at initial turn on
–
reduces
the peak inrush current value by a factor of 5...10 to protect
connectors and switching devices from damage. Subse-
quent switch-on cycles within short periods will cause an
increase of the peak inrush current value due to the warm-
ing-up of the NTC resistor. See also: E option
Inrush Current Peak Value
The inrush current peak value (initial switch-on cycle) can
be determined by following calculation:
