Special functions

Some of the special functions that can be set using the software are:
1. Extension of the PLL range: it allows to expand the locking interval of the network frequency with range ±2% to
±14%.
2. Setting of the output frequency (50Hz 60Hz).
3. Bypass activation speed: this function is useful for example with load with short and repeated inrush occurrences
(such as laser printers).
4. Automatic restart after end of autonomy: the UPS automatically restarts when the power network connection is
reinstated, after a stop due to total discharge of the batteries. The function is enabled by default.
For more information on all the special functions see the UPS Communicator software guide.
