U/I Advanced output characteristic curve
The preset U/I Advanced output characteristic curve is
optimized for the following applications:
–
For selective tripping of standard circuit breakers (SFB
technology). The power supply supplies up to 6 times
the nominal current for 15
ms. Loads connected in
parallel continue working.
–
When supplying loads with high switch-on currents,
such as
motors. The dynamic boost of the power supply
supplies up to 200%
of the nominal power for 5
s. This
ensures that sufficient reserve energy is available;
overdimensioning of the power supply is not necessary.
–
For system extension. With the static boost, up to
125%
of the nominal output power is available for a
sustained period (up to
40°C).
–
For fast energy storage charging (e.g.,
of batteries) to
supply a wide range of loads. The power supply
operates in the nominal operating range. Energy supply
to the load is ensured.

Smart HICCUP output characteristic curve
The SMART HICCUP output characteristic curve keeps the
thermal load of the connecting cables at a low level in the
event of a sustained overload. If loads are not protected or
are protected in a way that is not permitted, the loads are
supplied for 2
s. The DC output of the power supply is then
switched off for 8
s. This procedure is repeated until the
cause of the overload has been remedied.
The preset Smart HICCUP output characteristic curve is
optimized for the following applications:
–
If only a low short-circuit current is permitted.
–
If following an overload or short circuit the output
voltage should be made available again automatically.
