Device for controlling a plurality of electrical consumers

A device for controlling a plurality of electrical consumers which receive a constant control current at the respective control nodes (CH1, CH2), comprising:

• a transformer unit receiving a regulated and/or constant current of a predetermined frequency on the primary side and having a winding (80) without a tap on the secondary side, a first circuit branch forming a first control node (CH1) for a first electrical consumer and a second circuit branch forming a second control node (CH2) for a second electrical consumer being assigned to the winding,
• the first and the second circuit branches having a pair of oppositely wound and magnetically cooperating chokes (82, 84),
• wherein a first choke (82) of the choke pair is in contact with the first control node via rectifiers (32), and a second choke (84) of the same choke pair is applied to the second control mode via rectifiers (34),
• and a demagnetizing unit having an auxiliary winding (86), which cooperates magnetically with the choke pair is assigned to the choke pair.

A device for controlling a plurality of electrical consumers which receive a constant control current at the respective control nodes (CH1, CH2, CH3, CH4), comprising:

• a transformer unit (10) receiving a regulated and/or constant current of a predetermined frequency has at least one first winding (12) and one second winding (14) on the secondary side having a shared pickup,
• a first choke of a first choke arrangement (70, 72), which is connected to a first one (CH1) of the control nodes via rectifiers (D1) is connected downstream from the first winding, and a third choke of the first choke arrangement is also connected downstream and is connected to a second one of the control nodes (CH2) via rectifiers (D2),
• a second choke of the first choke arrangement, which is connected to the first one (CH1) of the control nodes via rectifiers (D1), is connected downstream from the second winding, and a fourth choke of the first choke arrangement is connected downstream from the second winding and is connected to the second one (CH2) of the control nodes via rectifiers (D2),
• one oppositely wound choke of a second choke arrangement (80, 82) is connected upstream from the second and fourth chokes, said choke arrangement being provided between the first and/or second windings of the transformer unit on the secondary side, said chokes of the first choke arrangement being connected to the respective control nodes and being oppositely wound from one another,
• and the chokes of the first choke arrangement and the chokes of the second choke arrangement are each coupled magnetically to one another, in particular having a common choke core.
