Because I have developed some projects, I have made some 51 series circuit boards, SMD design, with AD conversion, using thyristor output, can drive 220v/500w load (single channel), is there any need?...
The purple part in the picture may be connected to 220V mains power
To reduce the configuration resistor,can I use a 1N4007 to isolate 24V and 220V?
When the high voltage circuit is connected to 220V,...
