specified terminal.

 

 
 

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.
