The "Vision" display may be installed in all types of cubicles (UPS or Static Switch Cubicle).

The "Vision" display can operate in two different modes:

◗mono-cubicle: the "Vision" display monitors only the cubicle in which it is installed;

◗multi-cubicle: "Vision" display can monitor all system cubicles (up to eight maximum). In this mode, the system is equipped with only one "Vision" display which may be installed in any of the cubicles.

Installed in a special enclosure, the "Remote vision" display provides the user with remote indications on system status.

Insulating and Mains 1, Mains 2 and load voltage matching transformer

This transformer may be used to match Mains 2 voltage to that of the inverter, to create galvanic insulation between the load and the Mains or to create the appropriate neutral system.

Harmonics filter and power factor improvement

This option, placed on the Mains 1 input upstream from the inverter, reduces the reinjection of harmonic currents into the mains. Harmonic reinjection, produced by the rectifier/ charger, increases distortion on the mains.

The amount of the increase depends on the source impedance. The reduction in distortion reduces the risk of disturbing other sensitive loads connected to the mains. The filter can also increase the power factor upstream from the inverter.

Three types of filter are available:

◗uncompensated filter for the advantages listed above;

◗compensated filter for the advantages listed above and to limit the capacitive current absorbed by the filter (additional inductance), in the event the UPS is supplied by an engine generator set;

◗phase shift filter, an economical solution to limit the reinjection of harmonics on the mains.
