Function
Output characteristic curve
The device functions following the U/I characteristic curve.
Under load, the working point follows this curve. The output
current is limited in the event of a short circuit or overload.
Thereby, the device does not switch off, but rather supplies
a continuous output current.
The secondary voltage is reduced until the short circuit or
overload on the secondary side has been remedied. The U/I
characteristic curve ensures that both heavily capacitive
loads and loads with DC/DC converters in the primary circuit
can be supplied. Downstream fuses are triggered. Selectivity
in the design of your system is guaranteed at all times.

Thermal behavior
With an ambient temperature of up to +55°C, the device sup-
plies the continuous output current of I
N
. In the case of ambi-
ent temperatures above +55°C, the output current must be
reduced by 2.5% per Kelvin increase in temperature. The de-
vice does not switch off at ambient temperatures of +70°C or
thermal overload. The output capacity is reduced as far as
necessary to provide device protection. After it has cooled
down, the output capacity is increased again.
