AVT3218 A + - power controller with LCD display. PCB board and programmed layout

Description

The system is a power regulator of devices powered from 230V AC mains. The prototype served as a power regulator for the soldering iron, but the system can also work with other types of heaters up to 300W. In addition, it works well with classic bulbs and with LED bulbs and compact fluorescent lamps with "dimmable" function. Successfully passed the tests also with a commutator motor, squirrel cage and transformer. However, the power of such receivers, other than resistive, should not exceed 100W. A certain limit of the system is the minimum power, which should not be less than 10W.
