2.0 Theory of Operation The FlexNet MPS48-7M multipurpose power supply provides fi ltered 50W output power for a typical 48V telecom bus during normal line operation. During line disruptions, the MPS48-7M supplies uninterrupted output power of 50W directly from a string of four 12V batteries. Metal oxide varistor (MOV) technology provides line voltage surge suppression in the event of line cross or power spikes. An electromagnetic fi lter conditions line voltage, enabling the power supply to
