Re: Line Filtering

There is an 18Mhz crystal to clock the PIC. Other than that, nothing else that should act as an oscillator

Re: Line Filtering

I was going to use a simpler AC to DC converter something like this...

It has some type of line filter built in. Do I need another before this?Re: Line Filtering<br /> <br /> I ...r before this?Re: Line Filtering

Hi everyone,

I am trying to design a PCB with an IEC input , line filter and AC-DC converter and I need a bit of help with line filters.

100 - 240vac to 15vdc. about 2 amps. All mains components are to be PCB mounted.

I want this device to be EMC compliant but we are not a big company with large budgets for EMC testing. We do aim to have this device (a sensor display) tested but we would prefer to avoid repeat testing. We are looking as BS 61326 (Electrical equipment for measurement, control and laboratory use) So lets begin with the power inlet and...

Hi All,

Just joined here very recently. I work for a company designing sensors. My usual electronics boffins hates dealing with mains level voltages so I guess its up to me. Good luck everybody!!
