220V 800W Lamp Flasher Circuit Electronic

The circuit which is more simple, 400V capacitor, the bridge rectifier, the zener diode and the capacitor 100uF form the power supply voltage which obtained approx. 9v from transformerless power supply. The integrated 555 and its annexes components generate a train of pulses applied on the triac optocoupler MOC3021 driven intermittently causing the lamp on and off continuously. The triac may be a 2N6073A or TIC226D. By changing the 100K resistor or 1uF capacitor, then the flashing time will changed too. The rectifier bridge may be four 1N4007 diodes or 400v bridge diode with 1A current. The triac should be mounted on a heat sink to prevent over heating

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.

In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
