Description

Schaltpotentiometer Bei elektronischen Speisegeräten, deren Ausgangsgleichapannung in weiten Grenzen einstellbar ist, muß die Spannung des die Regelschaltung speisenden Gleichrichters wegen des begrenzten Regelbereichs jeweils der eingestellten Ausgangsspannung angepaßt werden. Bei aufwendigen Geräten geschieht dies beispielsweise dadurch, daß ein Stelltransfor- mator vom Ringkemtyp mechanisch mit dem Sollwerteinoteller gekuppelt ist. Bei Xleingeräten ist dies nicht möglich, Hier ist es üblich, die Aus « gangMpannung dadurch einzustellen, dttB die Transfermatoranzapfungen mittels eines Stufenschalters umgeschaltet werden, wobei gleichzeitig ein im Ausgangskreia liegend « Potentiometer zur Feineinstellung be- dient werden muß, Eine derartige Spannmgsregelung ist umständlieh ! B% handhaben. wenn beispielsweise ständig ein Stellbereich benötigt wirdg innerhalb dessen eine Umschaltung erforderlich ist. Dieser Nachteil last sich dadurch vermeidene daß neuerungegemäß das Einstellpotentiometer für die aUsgangsspannung, das üblichersweise mehrere Umläufe besitzt, mit einer Nockenscheibe versehen wird, die einen Schaltfedersat@ : betätigt. Über diese Schaltfedern werden dann die einzelnen Transformatoranzapfungen direkt oder über entsprechende Relais umgeschaltet, Das neuerungsgeMM Schaltpotentiometer ist in Figur 1 dargestellt. Switching potentiometer In the case of electronic power supply units whose output DC voltage can be set within wide limits, the voltage of the rectifier feeding the control circuit must be adapted to the set output voltage due to the limited control range. In the case of complex devices, this is done, for example, by the fact that an actuating transformer The toroidal core type mator is mechanically coupled to the setpoint value plate is. This is not possible with Xle devices, here it is usual to switch off « To set the output voltage, dttB the transfermator taps can be switched by means of a step switch, at the same time a potentiometer in the starting circle for fine adjustment must be used, Such a tension control is awkward! B% handle. if, for example, an adjustment range is constantly required g within which a switchover is required. This disadvantage can be avoided by the fact that according to the innovation Setting potentiometer for the output voltage, which usually has several revolutions, is provided with a cam disk that actuates a switching spring set @:. The individual transformer taps are then switched via these switching springs either directly or via corresponding relays, The neuungsgeMM switching potentiometer is shown in FIG.

Es besteht aus dem eigentlichen Potentiometer 1, an dem eine Armatur 2 zur Befestigung und Lagerung der Schalteinrichtung angebracht ist. Letztere besteht aus dem Kontaktfedersatz 3, dessen Steuerfeder 3 a von der Nockenscheibe 4 betätigt wird. Die Nockenscheibe ist fest mit dem Zahnrad 5 verbunden und greift in das Ritzel 6 ein, das fest mit der Achse 7 des Potemtiometers verbunden ist.It consists of the actual potentiometer 1, on which a fitting 2 is attached to the attachment and storage of the switching device. The latter exists from the contact spring set 3, the control spring 3 a of which is actuated by the cam disk 4 will. The cam disk is firmly connected to the gear 5 and engages with the pinion 6 a, which is firmly connected to the axis 7 of the potentiometer.

Die einzelnen Stufen auf der Nockenscheibe 4 sind dabei so gestaltet daß gemäß der in Figur 2 als Anwendungsbeispiel dargestellten Schal- tung die einzelnen Wioklung. absehnitte deo Transformators je nach Drehrichtung der Reihe nach an-oder abgeschaltet werden. The individual steps on the cam disk 4 are designed so that according to the switching shown in Figure 2 as an application example tion the individual Wioklung. Absehnitte deo transformer depending on Direction of rotation can be switched on or off in sequence.
