can help me guys how to use an opto coupler in a circuit.
i just experince repairing switch mode power supply I suspected a defective opto coupler, then I replace it (PC817). The Tv set powers on.
Another experince is when I check for resistance in the pin 4 (PC817) of a opto coupler the LED for stand by circuit the LED blinks.
Can you help with this guys Im confused on how a opto coupler used in a circuit like for example in the switch mode power supply, how a opto coupler isolates the high voltage section and low voltage section?
sorry for this question? I always want to explore more in electronics.
thanks. GOD BLESS YOU ALL.
