So this new Tyco Kilovac EV200A1ANA contactor requires an economizer to avoid coil overheating and getting damaged
Talking a lot on the phone and by mail about it with my dad, he told me to see if the coil was realy overheating and that is what I did using a small 12V AGM battery as a 12V source and also wired an ampmeter - in series - to see the current going in
3,5A showing here and 3A after few minutes
Not showing on this picture but the temperature went up to 30°C when I left the power - 12V @ 3,5A - on the coil leads for more than 5 minutes, so it is getting warm and consuming some power - 36W or more -
I am still reading einteresting stuff online to make a simple economizer with a simple resistor and a capacitor ,in parallel, wired in series with the coil : http://www.diyelectriccar.com/forums/showthread.php/evdl-coil-economizer-13711.html
