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.
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 of the respective output.
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 module is forced to supply a minimum cur-
rent 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 which will cause
an increase in case temperature. Consequently, a reduction
of the 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 module. 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 possi-
ble.
If output terminals are connected together in order to estab-
lish multi-voltage configurations, e.g. +5.1 V,
±12 V etc. the
common ground connecting point should be as close as
possible to the connector of the converter to avoid exces-
sive output ripple voltages.
Auxiliary outputs should never be connected in parallel!
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 T
C 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. 50% of its nominal value as per
figure.
