Switching power supply system and frame

The utility model discloses a switching power supply system and frame for the communications field, include: power supply output module, switch module, distribution module and control module, the distribution module includes that at least N group has load unit's distribution unit, and every matched stack electricity unit all includes: load unit, a control switch and a storage battery, control module supplies power to load unit through a control switch module and a control switch, obviously, control module supplies power to load unit through a control switch module and a control switch, it is that an accessible switch module and a control switch control to each power supply of organizing load unit to be control module, therefore, storage battery's in the different distribution units type may not be unanimous, and simultaneously, because the storage battery in every matched stack electricity unit is the independent control module that is controlled by, thereby can also realize one set of switching power supply of a plurality of operators sharing.
