Thermal behavior
With an ambient temperature of up to +40°C, the device
supplies the continuous output current of I BOOST . The device
I N
can supply a nominal output current of I N with ambient
temperatures 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 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.
Parallel operation
Devices of the same type can be connected in parallel to
increase both redundancy and power. By default upon
delivery, no further adjustments are required.
If the output voltage is adjusted, a uniform distribution of
power is guaranteed by setting all parallel operated power
supply units to exactly the same output voltage.
To ensure symmetrical current distribution we recommend
that all cable connections from the power supply unit to the
busbar are the same length and have the same cross section.
Depending on the system, for parallel connection of more
than two power supplies a protective circuit should be
installed at each individual device output (e.g., decoupling
diode, DC fuse or circuit breaker). This prevents high return
currents in the event of a secondary device fault.
Redundant operation

Redundant circuits are suitable for the supply of systems
which make especially high requirements on the operational
safety. If a fault occurs in the primary circuit of the first power
supply unit, the second device automatically takes over the

entire power supply, without interruption, and vice versa. For
this reason, the power supply units to be connected in parallel
are dimensioned in such a way that the total current
requirement of all consumers can be completely covered by
one power supply unit. 100% redundancy makes external
