Output Overvoltage Protection  
Thermal Considerations  
The outputs are protected against overvoltage by Zener  
diodes. In the event of an overvoltage, the converter will shut  
down and attempt to restart automatically. The main purpose  
of this feature is to protect against possible overvoltage,  
which could occur due to a failure in the feedback control  
circuit. The converters are not designed to withstand external  
overvoltages applied to the outputs.  
If the converter, mounted on a PCB, is located in free, quasi-  
stationary air (convection cooling) at the maximum ambient  
temperature TA max (see table Temperature specifications) and  
is operated at nominal input voltage and output power, the  
case temperature TC measured at the measuring point of  
case temperature (see Mechanical Data) will approach 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, such as input voltage, output  
current, airflow, temperature of surrounding components and  
surfaces, and the properties of the printed circuit board. TA max  
is therefore only an indicative value, and under practical  
operating conditions, TA may be higher or lower.  
Connection in Series or Parallel  
The outputs of single- or double-output models can be  
connected in series without any precautions, taking into  
consideration that the output voltage should remain below 60  
V for SELV operation.  
Caution: The case temperature TC measured at the measuring  
point of case temperature (see Mechanical Data) may under no  
circumstances exceed the specified maximum. The installer must  
ensure that under all operating conditions TC remains within the  
limits stated in the table Temperature specifications.  
Both outputs of double-output models can be connected in  
parallel without any precautions. Several converters (single-  
or double-output models) with equal output voltage can be put  
in parallel and will share their output current quite equally.  
However, this may cause start-up problems and is only  
recommended in applications, where one converter is able to  
deliver the full load current, e.g., in true redundant systems.

Short-Circuit Behavior  
Vo versus Io (typ.) of single-output models with Vo = 5.1 V  
The current limitation shuts down the converter, when a short  
circuit is applied to the output. It acts self-protecting, and  
automatically recovers after removal of the overload condition.
