lesl Posted March 27, 2011 Report Share Posted March 27, 2011 Hi: What voltage could I expect to see on the output terminals of a VSD say at 10 HZ Three phase System LesL Link to comment Share on other sites More sharing options...
marke Posted March 27, 2011 Report Share Posted March 27, 2011 Hello LesL At 10 Hz, you would get a voltage of 20% of the line voltage (assuming 50Hz supply) or 16.6% of line voltage for a 60Hz system. You will probably have dificulty measuring this due to the PWM nature of the output waveform. Best regards, Mark.

AB2005 Posted March 28, 2011 Report Share Posted March 28, 2011 Moreover, it depends upon the V/HZ ratio setting in inverter. "Don't assume any thing, always check/ask and clear yourself". Link to comment Share on other sites More sharing options...
