ac variable resistor
Hi,
I am working on a 230Vac dimmer circuit,
and has encountered a question.
Is there a digital variable resistor for 230Vac.
I don't think a digital potential meter will
work on the variable resistor on a AC dimmer circuit.
I saw on a website where it recommend a
opto- LDR devices but I couldl not found any.
Another solution is to do switching for
the resistor value, but it will takes up too
much space.
I can't think of any other solution.
Is there anyone familiar with digital AC dimmer?
Thank you for your help.
