AC voltage supplying a clean output voltages (see Fig. 1).
When an important voltage fluctuation is detected, the
UPS switches from normal performance to the autonomy

mode, and the batteries supply the power to the loads (see Fig. 2). As soon as the mains is restored to an acceptable
level, the
UPS automatically transfers back to the inverter and will conditionate the power to the equipment by means
of the DC Bus. Batteries will be recharged. During all the operation there is no transfer time from AC voltage to battery
and viceversa.
Furthermore, the batteries charge automatically when the unit is simply connected to the mains, regardless of
whether the
UPS is running.
These UPS are designed at high frequency (PWM) without transformer, and are very compact and suitable for any
applications where electronic equipment has to be supplied.
By way of its own protection, the
UPS will commute to Bypass in the event of overloading or inverter failure and will
automatically transfer to the inverter when the overload is removed (see Fig. 3).
All
UPS may be supplied in a cabinet ( NX version), or in rack format ( NX R version), and optionally their autonomy
may be extended by battery modules supplied in a metal case, through connector (4) .
All devices with the optional "Input polarity detector", are identified with a "P" behind the model.
