MGE UPS SYSTEMS SPTC5 500 UK – 09/2005 page

Optimised protection for applications such as data centres,

telecommunications and industrial processes

Galaxy 5000 meets the needs of the most sensitive applications in terms of high energy availability,

installation flexibility and control over operating costs through a set of specific advantages:

 Data centres - high energy quality and availability are combined with a wide range of power-upgrade

possibilities from a few dozen to several hundred kVA, easily, in complete safety and without interrupting

operations.

 Telecommunications - uninterrupted, mission-critical operation 24/365 is ensured by redundant

architectures. Long backup times are guaranteed by continuous battery monitoring and installation supervision

via computer networks or the internet. These systems increase availability and make it possible to plan

preventive maintenance.

 Industrial processes - operation in severe environments is possible due to the robust electrical

characteristics capable of handling disturbed distribution systems and a vast catalogue of options and

functions (reinforced IP, Ni-Cad batteries, marine versions, etc.).

1.2 The answer to the most demanding situations

Highest availability

The performance level of Galaxy 5000 contributes to providing high-quality energy 24/365 in all environments

and for all applications.

 Double conversion (VFI as per IEC 62040-3/EN 62040-3), providing regeneration of the output voltage and

frequency.

 PFC rectifier with sixpack IGBT modules to avoid disturbances on the upstream system:

- low current distortion upstream, THDI < 3%

- input power factor (PF) > 0.99.

 Digital control (free frequency) of the voltage combined with the sixpack IGBT modules, ensuring:

- a wide input-voltage range from 250 to 470 V, depending on the percent load, suited to all types of

applications and disturbed distribution systems

- high quality and stability of the output voltage, THDU < 2% (linear and capacitive loads)

- high dynamic performance for load-step changes (< 2% for 100 to 0% and for 0 to 100%), return to the +1%

range (rms value) in less than 100 ms.

 Backup time remains available due to digital management of batteries and the Digibat system that checks

and enhances battery status, and informs the user. The B1000 and Cellwatch battery-monitoring systems are

available for monitoring of each battery block.

 Powerful standard charger for long battery backup times (several hours) and fast recharging (10 minutes of

backup time in less than 11 hours and 4 hours of backup time in less than 24 hours, i.e. 90% of battery

capacity).

 Discrimination due to high overload capacity (2.2 In for 1 second) and a permissible crest factor of 3 to 1.

 Redundancy with up to four UPS units to protect servers requiring high availability.

 Automatic static switch for no-break transfer to AC power if an internal fault occurs (fault tolerance).

 UPS servicing and replacement of communication cards and battery modules without interrupting operation.

 Cold start on battery power if AC power is not available.
