ARRANGEMENT PROVIDED WITH A RECORDING DEVICE

摘要

The invention relates to an arrangement (1) comprising a recording device, in particular a tachograph (2) for a motor vehicle, a voltage source (3) supplying power to the recording device and a sensor (S) transmitting a signal thereto, wherein different modules (7, 8, 9, MEM) of the recording device consume energy and are embodied in such away that they are connectable and disconnectable. In order to solve, in particular, a problem of a relatively unstable voltage supply, the aim of said invention is to design a system whose operation is low-affected by the voltage oscillations and interruptions and which is not overcharged by a just unstable energy supply. For this purpose, several (7, 8, 9, MEM) modules are disconnectable or connectable when the energy supply operating voltage (U) is modified.
