Overview
|
This specification defines the performance characteristics for a class Ⅱ adapter, single-phase 12.0 watts. Single output level power supply.
◆ Simple design philosophy.
◆ Reliability level of 50K hours MTBF @ 25° C (rated input voltage and using the Telcordia SR-332 issue 3 method).
◆ DC output voltage must be Safe Extra Low Voltage (SELV) & Limited Power as defined by IEC62368-1.
◆ The maximum room ambient temperature (Tmra), as mentioned in clause B.1.6 and B.2.6 of IEC62368-1, for the external power supply is 40°C.
◆ Cooling: natural convection.
