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

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.

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.

Options (cont.)

The "Vision" display may be installed

in all types of cubicles (UPS or Static

Switch Cubicle).

"Vision" display

"Remote vision" display

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.
