Regulated Switch Mode Power Supplies
The ambient temperature is a determining factor that limits the power an electronic power supply can deliver continuously. If the temperature around the electronic components is too high, their life will be significantly reduced.
The nominal ambient temperature for the Modular range of Phaseo power supplies is 55°C. Above this temperature, derating is necessary up to a maximum temperature of 70°C (except for the ABL7RM24025 model).
The graph below shows the power as a percentage of the nominal power that the power supply can deliver continuously, depending on the ambient temperature.
