The invention concerns an intrinsically secure device for supplying redundant current-voltage for an electricity receiver in a zone protected against explosions. The device is of the type comprising at least two supply circuits for providing a current-voltage supply, and an intrinsically secure protective device for limiting a current-voltage supply of the power supplying the receiver in a zone protected against explosions. The inventive device is characterized in that the supply circuits are mounted mutually parallel, and the protective device includes at least a resistive current limiter ensuring intrinsic security when the supply circuits are activated in parallel. |
