MGETM GalaxyTM 6000 : Specification guide
Parallel UPS, three-phase, 250 to 3000 kVA*
* Power rating for an N+1 redundant configuration
2.6 - UPS maintenance
For maintenance purposes, all electronic components shall be accessible from the front of the UPS. In addition, a manually operated mechanical bypass system shall be:
…………………………………………………………………………………………………………………………………..
-Built into each UPS unit () for a
…………………………………………………………………………………………………………………………………..
-Installed separately in the external maintenance bypass cabinet () with external
…………………………………………………………………………………………………………………………………..
-Installed separately in the centralized bypass () with
This system shall be designed to isolate the UPS while continuing to supply power to the load from the bypass AC source. The UPS shall also include a device making it possible to isolate the rectifiers and the chargers from the normal AC source.
2.7 - Battery maintenance
For safe maintenance on the battery, the system shall include a circuit breaker to isolate the battery of each
2.8 - Cold start (normal AC source absent)
The battery of each unit shall be capable of ensuring UPS
3 - Sizing and general characteristics
3.1 - Technology
Each unit in the UPS system shall be based on IGBT technology with
3.2 - Rating
The UPS system shall be sized to continuously supply a load ofkVA, at a power factor (pf) of 0.8.
It shall be made up of ...[2 / 3 / 4 / 5 / 6]... UPS units, each with an identical rating of ...[ 250 / 300 / 400 / 500 / 600]... kVA.
The total installed power rating shall thus be |
| kVA. ...[Consequently, 1 (or 2) unit(s) may be redundant.] |
3.3 - Battery backup time
The battery backup time in the event of a normal AC source outage shall be _______ minutes, for a load power
factor of 0.8.
Battery service life shall be equal to at least …[ 5 / 10 ]…years. It shall be selected and sized correspondingly, for a load power factor of 0.8.
3.4 - Types of loads accepted
The UPS shall accept high crest factors (3:1) without derating to ensure correct operation with computer loads. The total harmonic voltage distortion at UPS output (THDU downstream) shall respect the following limits:
ωTHDU downstream ph/ph and ph/N ≤ 4% for linear loads;
ωTHDU downstream ph/ph and ph/N ≤ 4 % for
