8.4. OPERATION IN HIGH EFFICIENCY MODE
The UPS makes it possible to select a programmable economy operating mode that can increase overall efficiency up to 98% for
energy saving purposes. If the power supply fails, the UPS will automatically switch onto the inverter and continue to supply power
to the load by drawing energy from the battery. This mode does not provide perfect stability in frequency and voltage like the ON
LINE mode. Thus the use of this mode should be carefully evaluated according to the level of protection required by the application.
Eco Mode operation provides very high efficiency, since the application is powered directly from the auxiliary mains via the automatic
bypass in normal operating conditions.
8.5. OPERATION IN CONVERTER MODE
ITYS PRO can operate as a frequency converter. For such use please contact SOCOMEC.
WARNING!
SOCOMEC recommends using the converter mode only for UPS with separate auxiliary mains and auxiliary mains
disconnected from the power source.
