Am Ausgang S., gibt er eine mit Hilfe der Zenerdiodo Z^ stabilisierte Gleichspannung τοη beispielsweise +30 Y ab; an den^ Eingang S2 liegt eine Vergleichsspannung an.The voltage stabilizer I is known per se and. is therefore not explained in detail. At its input S it receives a voltage of 45/50 T 9 which is derived from the voltage network after transformation. At the output S., it emits a DC voltage τοη stabilized with the help of the Zener diode Z ^, for example +30 Y ; A comparison voltage is applied to the ^ input S 2.
