150 – 280 Watt AC-DC Converters
Thermal Considerations
If a converter is located in free, quasi-stationary air
(convection cooling) at the indicated maximum ambient
temperature 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 components and surfaces. TA max is therefore,
contrary to TC max, an indicative value only.
Caution: The installer must ensure that under all operating
conditions TC remains within the limits stated in the table:
Temperature specifications.
Notes: Sufficient forced cooling or an additional heat sink
(applied to -7 or -9) models allows TA to be higher than 71 °C
(e.g., 85 °C), if TC max is not exceeded. Details are specified
in fig. 12, including -5 and -6 models.

-7 (equal to -9) models.
Thermal Protection
A temperature sensor generates an internal inhibit signal,
which disables the outputs, when the case temperature
exceeds TC max. The outputs automatically recover, when
the temperature drops below this limit.
Continuous operation under simultaneous extreme worst-
case conditions of the following three parameters should
be avoided: Minimum input voltage, maximum output
power, and maximum temperature.
Output Protection
Each output (and the connected equipment) is protected by
a suppressor diode against overvoltage, which could occur
due to a failure of the control circuit. In such a case, the
suppressor diode becomes a short circuit. The suppressor
diodes may smooth short overvoltages resulting from
dynamic load changes, but they are not designed to
withstand externally applied overvoltages.
A short circuit at any of the two outputs will cause a shut-
down of the other output. A red LED indicates an overload
condition.
Note: Vo BR is specified in Electrical Output Data. If this
voltage is exceeded, the suppressor diode generates losses
and may become a short circuit.
Parallel or Series Connection of Converters
Single or double-output models with equal output voltage
can be connected in parallel without any precautions using
option T (current sharing). If the T pins are interconnected,
all converters share the output current equally.
Single-output models and/or main and second outputs of
double-output models can be connected in series with any
other (similar) output.
Notes:
–
Parallel connection of double-output models should
always include both, main and second output to
maintain good regulation of both outputs.
–
Not more than 5 converters should be connected in
parallel.
–
Series connection of second outputs without involving
their main outputs should be avoided as regulation
may be poor.
–
Models with a rated output voltage above 36 V need
additional measures to comply with the requirements
of SELV (Safe Extra Low Voltage).
–
The maximum output current is limited by the output
with the lowest current limitation, if several outputs are
connected in series.
