Note 1: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground. Currents are positive into, negative out of
specified terminal
RECOMMENDED OPERATING CONDITIONS
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.
