It is powered by AC and DC two-way power supply, stable voltage can be exported by rectification and voltage stabilizing；And when any road
Power supply carries out overhauling, break down or time voltage pulsation is equal, all out-put supply will not be produced impact, thus improve control system
Stability can reliability.
Above example is the most for illustration of the utility model, rather than the restriction to this utility model protection domain.Relevant
Those skilled in the art, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various change
Change or modification, and within the technical scheme of all equivalents also should belong to the category of this utility model protection, by each claim
Limited.
