Output characteristics

Exceeding the nominal power (only applicable to ABL 7RM1202 and

ABL 7RM2401)

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.
