With a 120 ohms resistor this circuit can also be used as a shield for 3.3 V output voltages. The circuit uses an opto-diac enabling the control of triacs connected to the power grid with total isolation.
With this circuit it is possible to improve the standing wave ratio (SWR) of a transmission system with...
Using the ULN-3784B this circuit typically supplies 5 W at 24 W. However, it can operate from 9 V....
This circuit uses two relays that switch when the voltage exceeds the value given by zener D2. The...
