This is IC 4060 Timer circuit. When rises time that is set, Suppose set 5 minutes time. after all time to 5 minutes. the circuit will emit a sound of buzzer once. [...]
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…
This circuit prevents surges. From the opening is switched off or power failure. The damage to electrical appliances.
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.
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
