Applications

Galaxy 3000 is designed to meet the needs in terms of high availability and flexibility of sensitive equipment such as:

◗ computer rooms,

◗ internet (Internet Data Centres),

◗ telecom equipment,

◗ industrial processes, emergency lighting, laboratories.

Colour

Four colours are available:

◗ light grey,

◗ metal grey,

◗ metal blue,

◗ metal green.

For other colours, please consult us.

Maximum flexibility

Galaxy 3000 offers maximum flexibility to meet all needs.

◗ Backup times from 7 minutes up to 8 hours provided by batteries with 5-year or 10year service lives.

◗ Modular design for easy upgrades, such as increased power ratings or improved availability:

> parallel connection of up to four UPS units,

> hot-standby configurations,

> source redundancy with the Galaxy STS (static transfer switch).

◗ Wide input-voltage window extending down to 37% of the rated voltage for improved compatibility and fewer transfers to battery power.

Power Factor Correction (PFC) system for clean power

Galaxy 3000 ensures clean power through the PFC system that eliminates electrical disturbances on the upstream system and supplies downstream a power waveform offering exceptional quality.

This system implements a clean, high-performance IGBT rectifier/charger offering, without any further filtering:

◗ clean input current, with a sinusoidal waveform in phase with the voltage, thus eliminating harmonic disturbances (THDI < 3%),

◗ a high power factor (FP > 0.99),

◗ total compatibility with engine generator sets,

◗ a reduction in installation electrical consumption of up to 20%.

Battery Monitor for advanced battery management

The Galaxy 3000 Battery Monitor optimises the battery service life and continuously maintains a high degree of battery availability through the functions listed below:

◗ Intermittent charge cycle designed to prolong battery service life (fig. 4.22).

◗ Automatic detection of battery parameters, which are initialised during the first charge cycle and then automatically updated.

◗ Increased battery service life by taking into account the manufacturer parameters, with adaptation of the charge voltage to ambient temperature changes.

◗ Precise measurement of the true backup time depending on the age of the battery, the room temperature and the percent load on the UPS.

◗ Calculation of the remaining battery service life.

◗ Battery protection against deep discharge.

◗ Backfeed protection (optional) to protect users from the flow of power upstream toward the distribution system during operation on battery power.

◗ Limitation of the charge current (0.05 C10 to 0.1 C10).

◗ Numerous automatic tests.

High availability

◗ On-line double-conversion technology (VFI as per IEC 62040-3/EN 50091), that completely regenerates the power signal and the frequency, and guarantees constant power quality whatever the conditions on the distribution system.

◗ Automatic bypass for no-break transfers of the load to the bypass AC input if an internal anomaly occurs (fault tolerant).

◗ Hot-swap function for servicing on the UPS and replacement of communication cards and battery modules without interrupting the supply of power to the applications.

◗ Cold-start function for start-up of applications on battery power even during a utility power outage.

◗ Long backup-time charger (optional) for backup times longer than 30 minutes, offering a reduced charge time (8 to 10 hours for 80% of the rated backup time).

◗ Redundancy with up to four parallel-connected UPS units to protect highavailability servers.

Always check that the protection used complies with local standards and the specific features of the electrical installation including:

◗ withstand capacity with respect to the short-circuit current at the point of installation

◗ the maximum permissible current that the static switch semi-conductors can withstand

◗ discrimination with respect to UPS output protection when operating on the bypass.
