Hi,
My frequency counter is IC based with one of its pin as direct input.. about 6Volts. Now I want to measure the frequency of the power lines. I plan to use a step down transformer of 110 volts to
6 volts secondary. Can I use the connect transformer
6 volts output directly to the pin of the IC.. or do I have to use some kind of current limiter. If so. What current limiter must I use? Or does the IC only draw the required few current it needs without the transformer overloading it? Thanks.
