Output Current Limitation
All outputs are continously protected against open-circuit (no
load) and short-circuit by an electronic current limitation.
Single- and double-output powertrains have a rectangular

Thermal Considerations and Protection
If a converter is mounted upright in free air, allowing
unrestricted convection cooling, and is operated at its
nominal input voltage and output power at T
Temperature specifications), the temperature measured at
the measurement point on the case T

However the relationship between T

thermal conditions are influenced significantly by the input
voltage, the output current, airflow, and the temperature of the
adjacent elements and surfaces. T

A temperature sensor fitted on the main PCB disables the
output, when the case temperature exceeds T
converter automatically resumes, when the temperature
drops below this limit. A temperature sensor on each power
train reduces the output current limit of that power train, when
the temperature exceeds a safe level.
Output Power at Reduced Temperature

the converters should not be packed too closely together! In such
cases the use of a 5 or 6 TE front panel is recommended.
