RECOMMENDED OPERATING CONDITIONS
This module has been designed to operate over a wide range of input and output conditions. However, bet 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 function optimally.
