ABSTRACT:
A device for intrinsically safe, redundant current-voltage supply for electric loads in an explosion-proof area. The device includes at least two supply circuits for making available the current/voltage supply and a protective device for intrinsically safe current and voltage limitation of the power supplied by the supply circuits to the load in the explosion-proof area. The supply circuits are connected in parallel to one another and the protective device has at least one resistive current limiting device for intrinsic safety in parallel-active supply circuits.
