PRESENTATION
SENTINEL PRO uses ON-LINE double conversion technology, resulting in the highest levels of reliability and maximum
protection for critical loads such as servers, IT applications and Voice/Data.
It is possible to use one or more autonomy expansion units known as BATTERY BOXES (optional accessories) with the
same dimensions and aesthetic line as the UPS alongside it.
The ER model UPSs fitted with upgraded battery chargers are the solution for Business Continuity applications which
require long battery-powered operating times. For these versions, the batteries are housed in separate cabinets which
are designed to contain large, high-capacity batteries.
