Output Characteristic and Protection
Each output is protected by a suppressor diode, which under
worst case conditions may become a short circuit. The
suppressor diodes are not designed to withstand externally
applied overvoltages. Overload at any of the outputs will cause
a shutdown of all outputs. A red LED indicates the overload
condition of the respective output.

Thermal Considerations and Protection
If a converter is located in free, quasi-stationary air (convection
cooling) at the indicated maximum ambient temperature T
(see table Temperature specifications) and is operated at its
nominal input voltage and output power, the temperature
measured at the measuring point of case temperature T

Parallel and Series Connection
Main outputs of equal nominal voltage can be connected in
parallel. It is important to assure that the main output of a
multiple-output converter is forced to supply a minimum
current of 0. 1 A to enable correct operation of its own auxiliary
outputs.
In parallel operation, one or more of the main outputs may
operate continuously in current limitation, causing an increase
of the case temperature T
max. ambient temperature by 10 K is recommended.
Main or auxiliary outputs can be connected in series with any
other output of the same or another converter. In series
connection, the maximum output current is limited by the
lowest current limit. Output ripple and regulation values are
added. Connection wiring should be kept as short as possible.
If output terminals are connected together in order to establish
multi-voltage configurations, e.g., +5.1 V, ±12 V etc., the
common-ground connecting point should be as close as
possible to the connectors of the converter in order to avoid
excessive output ripple voltages.
