I was recommmend to use ferric chokes.

Here is his exact quote.

"The solid state relays may be less sensitive to this EMI. But we need to employ MOVs and appropriate ferric chokes to reduce this further."

What is a ferric choke? It doesnt come up in google.

Many thanks.

ferrite choke

Tullos · Guest

Can I use a universal ferrite choke on an AC line going to a solid state relay that will turn on a motor AC? I'm trying to protect the solid state relay. Also, I was thinking about adding a 240v MOV. Do these combination sound good? Am I way off track?

http://www.ferrishield.com/html/round5.html#BC28B1251 is the specific one I was looking at.

I still dont quite understand the A B C D colums on the datasheet.

Many Thanks

Hi Tullos,

A,B,C and D columns reffer to phisical dimentions mark of the ferrites according to the drawing, expressed in inches (black colour) and milimeters (red colour)
