Disposition of unities of an uninterrupted power supply with buffer battery.

摘要

In order that the technical complexity which is unused in a power supply device that is not battery-buffered but is necessarily present, and the number of activities which have to be carried out during conversion are minimal, in order to be able to convert the power supply device which is not battery-buffered into a battery-buffered power supply device, an arrangement of units of a power supply device which can optionally be battery-buffered is proposed, having a power supply circuit part and a battery-buffering circuit part, which is characterised in that the power supply circuit part and the battery-buffering circuit part are in each case combined on a flat assembly (FBAT or FSTR respectively), which are fastened detachably, being opposite one another at least over a partial region, on the one side or the other of a supporting plate (TR) with respect to at least the flat assembly (FBAT) carrying the battery-buffering circuit part, and are electrically connected to one another in the overlapping partial region by means of a rigid plug connector system.
