Duty cycle pulsing via SCR 28 and opto-coupler 26 further raises usable voltage to 5.5V
The variable pulsing circuit comprises electronic switch SCR 28 operated from opto-coupler timing circuit 26, switching the pulsed d.c. voltage on/off for equal periods; this duty cycling raises the effective inhibiting limit to 5.5 volts (L-3), with blocking diode 29 eliminating stray electrons/shorts and blocking back-EMF.
