A circuit arrangement for supplying an output current to a load which is useable in power supplies and is connectable in parallel to other circuit arrangements, wherein effects of component tolerances on a uniform working load are avoided.

Circuit arrangement for supplying an output current to a load

An automation device having a plurality of modules, where at least one first module is configured to supply the other modules electrical power and a second module is configured to determine the total power requirement of the automation device, wherein the second module determines the total power requirement from the information relating to the power requirement of the respective module, which information is stored in the other modules, and compares the total power requirement with a threshold value and initiates measures for reducing the power requirement of at least one of the other modules based on the comparison result to prevent an overload due to improper or inappropriate installation of the automation device in a switchgear cabinet and resultant reduced air convection.
