Output Protection
Each output is protected against overvoltages which could
occur due to a failure of the internal control circuit. Voltage
suppressor diodes (which under worst case condition may
become a short circuit) provide the required protection. The
suppressor diodes are not designed to withstand externally
applied overvoltages. Overload at any of the outputs will
cause a shut-down of all outputs. A red LED indicates the
overload condition.
Parallel or Series Connection of Units
Single or double output units with equal nominal output
voltage can be connected in parallel without any precau-
tions using option T.
With option T (current sharing), all units share the current
approximately equally.
Single output units and/or main and second outputs of dou-
ble output units can be connected in series with any other
(similar) output.
Note:
– Parallel connection of double output units should always
include both, main and second output to maintain good
regulation of both outputs.
– Not more than 5 units should be connected in parallel.
– Series connection of second outputs without involving
their main outputs should be avoided as regulation may
be poor.
– The maximum output current is limited by the output with
the lowest current limitation if several outputs are con-
nected in series.
Thermal Considerations
If a converter is located in free, quasi-stationary air (con-
vection cooling) at the indicated maximum ambient tem-
perature
TA max (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 TC (see: Mechanical Data) will approach the
indicated value
TC max after the warm-up phase. However,
the relationship between
TA and TC depends heavily on the
conditions of operation and integration into a system. The
thermal conditions are influenced by input voltage, output
current, airflow and temperature of surrounding compo-
nents and surfaces.
TA max is therefore, contrary to TC max,
an indicative value only.
Caution: The installer must ensure that under all operat-
ing conditions
TC remains within the limits stated in the
table
Temperature specifications.
Notes: Sufficient forced cooling or an additional heat sink
allows
TA to be higher than 71°C (e.g. 85°C) if TC max is not
exceeded.
For -7 or -9 units at an ambient temperature
TA of 85
°C with
only convection cooling, the maximum permissible current
for each output is approx. 40% of its nominal value as per
figure.

Thermal Protection
A temperature sensor generates an internal inhibit signal
which disables the outputs if the case temperature exceeds
TC max. The outputs are automatically re-enabled if the tem-
perature drops below this limit.
It is recommended that continuous operation under simul-
taneous extreme worst case conditions of the following
three parameters be avoided: Minimum input voltage,
maximum output power and maximum temperature.
