This is On-off SCR control circuit with logic gate IC. SCR will turn ON when input A gets bias current. But SCR will turn off if its input B gets current.
All controller, motor speed driver,switches,timer,sensor,and more : Timer switches • DC motor speed control • Delay timers • Light switchs • SCR controls • Light dimmers • Infrared remote control system • and more…
The surge protection circuit important! Sometimes, our electrical appliances may damage easily by little high voltage surges. We can protect this problem.
The emergency light circuit will have battery backup charge to stored, But when electricity failure, it does opposite is battery will discharge into lamp
The special Relay that used replace normally relay, very fast contact load, low voltage input 3V to 24V only
This is overload protection for transformers and load, is simple circuit cut off-on by relay. And so fast switch witch SCR driver. can set sensitive by VR1
This is speed motor controller circuit of 12V DC motor. as SCR DC motor speed control circuit using IC-4081 CMOS. You can adjust the speed of rotation [...]
This is Sound switch circuit,using IC-1458 and SCR-C106D It will work only if the loud is overdue,for player cameras, can apply to a Burglar alarm circuit
