Abstract:
1. A set of roller conveyors having multiple members, the members of which are arranged to be connected to different local system voltages, each member of the set comprising: a plurality of driven rollers disposed in two parallel tracks; a plurality of electric drive motors for the driven rollers; a connector for connection to the local system voltage; wherein each member of the set has at least one individual electric feed-in block, which is different for each member of the set, while otherwise all members of the set have substantially identical components, the electric feed-in block is connectable to the local system voltage and from this generates an output voltage, which is the same for all members of the set and is lower than or equal to the lowest system voltage, for which a member of the set is designed; and, the drive motors of the driven rollers are designed for the output voltage of the feed-in block.
