Input Under-/Overvoltage Lock-out
If the input voltage remains below approx. 0.9
Ui min or ex-
ceeds approx. 1.1
Ui max, an internally generated inhibit sig-
nal disables the output(s). When checking this function the
absolute maximum input voltage rating
Ui abs should be
considered!
Inrush Current Limitation
The inherent inrush current value is lower than specified in
the prETS 300132-2 (ver. 3.1) standard. The units operate
with relatively small input capacitance resulting in low in-
rush current of short duration. As a direct consequence in a
power-bus system the units can be hot plugged-in or dis-
connected causing negligible disturbance at the input side.
Electrical Output Data
General Conditions:
–
TA = 25
°C, unless T
C is specified.
– Sense lines connected directly at the connector, inhibit (28) connected to Vi– (32).
– R input not connected; with option P,
Uo set to Uo nom at Ui nom.

1 If the output voltages are increased above Uo nom through R-input control, option P setting or remote sensing, the output power should
be reduced accordingly so that
Po max and TC max are not exceeded.
2 See: Output Current Limitation and Output power at reduced temperature.
3 In parallel and symmetrical configuration, Io nom = Io1 nom + Io2 nom.
4 See: Technical Information: Measuring and Testing.
5 Recovery time until Uo remains within ±1% of Uo, see: Dynamic load regulation.
