Output characteristic curve
At ambient temperatures T amb < +40°C, the device can con-
tinuously provide current I BOOST at nominal voltage.
In the event of a higher load, the operating point follows the
U/I characteristic curve depicted in the figure. In the event of
a short circuit or overload, the output current is limited to
< 60 °C
< 40 °C
I BOOST . Thereby, the device does not switch off, but rather
supplies a continuous output current. The secondary voltage
is reduced until the short circuit on the secondary side has
been remedied.
The U/I characteristic curve ensures that the heavily capaci-
tive loads and the consumers with DC/DC converters in the
input circuit can be fed without problems using QUINT PO-

supply a nominal output current of I N with ambient tempera-
tures of up to +60°C. In the case of ambient temperatures
above +60°C, the output current must be reduced by 2.5%
per Kelvin increase in temperature. The device does not

provide device protection. After it has cooled down, the out-
put capacity is increased again.
