ABSTRACT:
An arrangement for supplying a load with controlled current of a predetermined voltage which remains uniform notwithstanding variations in voltage of the alternating current supply, and notwithstanding differences in the frequency of the alternating current supply. A monostable trigger stage of the switch mechanism is connected to a DC voltage which is proportional to the voltage of the alternating current source, and its resistor which is connected with the capacitive coupling of the trigger stage transistors and determines the reset time of the trigger stage, is connected to a constant DC voltage. The mechanism includes a voltage divider, the division ratio of which is variable by means of a frequency recognition circuit.
