Power supplies for d.c. control circuits
Phaseo
®
modular regulated power supplies
The ambient temperature is a determining factor which limits the power that an
electronic power supply can deliver continuously. If the temperature around the
electronic components is too high, their life will be significantly reduced. Conversely,
a power supply can deliver more than its nominal power if the ambient temperature
remains well below the nominal operating temperature.
The maximum ambient temperature for Phaseo power supplies is 55 °C (131°F).
Below this temperature, uprating is possible up to 110% of the nominal power.
The graph below shows the power (in relation to the nominal power) that the power
supply can deliver continuously, according to the ambient temperature.
Power supply ABL 7RM24025 cannot exceed the nominal power of 60 W.
