Thermal Considerations 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. 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. Fig. 8a Vo versus Io (typ.) of single-output models with Vo = 5.1 V Fig. 8b Vo versus Io (typ.) of double-output models (2 ×12 V) with both outputs in parallel Short-Circuit Behavior 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. Output Overvoltage Protection 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. 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. 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.
