Ist seit Juli 2020 bei einer Drehbank mit Motor 380V 4kw im Einsatz..kam mit Enlisch-Manual aber für etwas versierte die sowas einbauen verständlich. Wird selbst bei 7Std. Schicht an Drehbank ( keine Minidrehbank ) nicht warm. Bißchen negativ ist vielleicht das kein Plan für Bedienfeld dabei ist da internes Kabel etwas zu kurz ist um 1 Meter zu überbrücken. War etwas basteln angesagt. aber mindert nicht meine Rezension.
