#175672 - varistor? Responding to: ???'s previous message |
Hi , Kai,
You mentioned 2 times here about surges. It's not advisable to use varistor against them? BTW, i want to correct myself - circuit with 2 optocouplers, drawn by You, can deliver very good angle resolution - if microcontroller has enough timer/capture resources. regards |
