The electronics comprises a load circuit, a power supply circuit having a rechargeable electrical energy storer, and a protection circuit. An input of the power supply circuit is adapted to be electrically connected with an external energy supply. Both the power supply circuit and the protection circuit have at least two operating modes. Additionally, the protection circuit is adapted in the first operating mode to monitor the cell voltage applied on the circuit input to determine whether its voltage level has exceeded a predetermined maximum value and, in given cases, automatically to deactivate the operating mode.

Hybrid voltage supply for a measuring instrument

The terminal block () serves for electrically connecting a connection line having at least two conductors (L, L) and extending externally of an electronics housing (H). The terminal block comprises a platform () composed at least partially of an electrically insulating, synthetic material, especially a synthetic material having a dielectric strength sufficient to meet European standard EN 60947-1, a connection terminal (TI) arranged on a first side of the platform forming a first connection side of the terminal block and serving for connection of a conductor (L) of the connection line as well as at least one connection terminal (T) arranged on the first side of the platform, laterally spaced from the connection terminal (T) for connection of a conductor (L) of the connection line. Additionally, the terminal block comprises a connection contactor (J) arranged on a second side of the platform forming a second connection side of the terminal block, e.g. especially a connection contactor embodied as a contact pin or as a contact jack, as well as a connection contactor (J) arranged on the second side of the platform and laterally spaced from the connection contactor (J), e.g. a connection contactor embodied as a contact pin or as a contact jack.
