<p>RetrEVnoc: added technical info based on benchtop measurements</p> <hr /> <div>&quot;contactors get extremely hot from 12v power when closed for extended periods of time&quot; ([https://openinverter.org/forum/viewtopic.php?f=10&amp;t=738&amp;p=10661#p10657 here])<br /> <br /> Testing suggests that Tesla contactors require economizer circuits and it's important to note that the Open Inveter boards do not currently implement this functionality.<br /> <br /> Model 3 contactor 12v amperage pull measured at 8.3A continuous (without economizer). <br /> <br /> GIGAVAC publish an application note on how to use contactors ([https://www.gigavac.com/sites/default/files/AN-016-Driving-Contactors-w-External-PWM.pdf here])</div>
