accurate item and fast delivery. received to the UK in 2 weeks.
Fast shipping, well packaged. These are great value controllers, that can be used with or without a kt lcd display. It seems to be a new version with k150e09ne Toshiba mosfets (Rds 3.6 mOhm, rated 85v and 150 amp each @ 25C), which is good. The new phase current sensor (sine wave controller) is much smaller than the old 18 fet sinewave kt controller I have, which is not so nice. It also has a tiny shunt wire to bypass some current. I might try to upgrade with a stronger acs758 current sensor in the future. The new controller starts as a loud square wave and then switches over to a more silent sine wave quite abruptly. The old version I have seems to start as sine wave immediately and is much more quiet and smooth. So all in all this new version is still a good value controller, but not as nice, silent and powerful anymore as the old version I have. If you have technical skills, you could also modify it with custom firmware; then you can change almost anything you want.
