Power supply arrangement
First Claim
1. A power supply arrangement of the type having a controlled operating power output and a controlled buffer output, the buffer output being connected to a plurality of read-write memories of a computer, the read-write memories being switched to a stand-by mode and connected to a back-up power source upon a failure of the line voltage, the improvement therein comprising:
- low impedance first switch means responsive to a first switch control signal for connecting the read-write memories for active operation to the power output during normal line conditions, andsecond switch means responsive to a second switch control signal for connecting the back-up power source via a first series controller to the buffer output.

Abstract
A power supply arrangement (2) with a first controlled power output (12) and a second controlled output (26) also has a controlled backup output (16) which is connected by means of a buffered bus with several read/write memories (8) of a computer (4). The read/write memories (8) of the computer (4) can be switched over to a stand-by mode in case of a power failure and connected with a backup battery (20). In accordance with the invention, the read/write memories (8) are switched during normal network operation to an active operating mode connected by means of a low-impedance switch (34) with the controlled power output (12). The low-impedance switch (34) is controlled by means of a switching signal (US1). The backup battery (20) is connected with the controlled backup output (16) via a second switch (46) and a series controller (48).
