Low voltage flasher


Posted on Mar 23, 2013

Applying voltage to the circuit triggers SCR1. With SCRl on, the voltage on the anode of SCR2 rises until SCR2 triggers to commu-tate SCRl. The voltage on the gate of SCRl will swing negative at this time, and only after a positive potential of 0 volt is once again attained, will SCRl retrigger

The circuit could be used for higher voltage levels, but the peak negative voltage on the gate of SCRl must be limited to less than 6 volts.
