RECOMMENDED OPERATING CONDITIONS (R.C.)
This module has been designed to operate over a wide range of input and output conditions. However, best efficiency and performance
will be obtained if the module is operated under the condition listed in the ‘R.C.’ column. Min. and Max. columns indicate values beyond
which the inverter, although operational, will not function optimally.
