What is the grid frequency that can be applied on Compact NSX with Micrologic


The main problem is frequency.
Compact NSX equipped with micrologic works properly according the catalogue specifications for a frequency within 45 to 65Hz as per IEC-60947.
Below 30 Hz the accuracy of measured current by the MI trip unit is very low what can create mismatching information for the unit.
This is due to the sampling frequency of the unit and ca cause unwanted tripping.

But in general we cannot guarantee that for out of range frequencys the trip unit will operate properly.
The 400Hz application is the only exception that we describe in the catalog
