This circuit was obtained from an American documentation from the 1980s. The T1 triggering transformer must provide 250 V pulses for the lamp to trigger.
The output voltage of this unit is approximately 1.4 V less than that of the chosen zener. The...
Found in the April 1980 issue of Radio Electronics magazine, this stage uses transistors from the...
To control direct current loads, under voltages between 12 and 200 V, and currents up to 3 A, we...
