Fuji Electric MP2A5077
This means that a sub-power supply is required at standby time which adds to the size of the unit. The M-Power2A series of special power devices have been developed for the Converter.FEATURES

FB pin Warning MT5F18467 -2- Quality is our message 1. Outline In recent years switching power supplies have been required to be not only compact and light weight but also to have low power consumption and a high power factor. A current resonant converter is applied, because it is superior to other topology from the viewpoint of low noise and efficiency.
