MGETM GalaxyTM 6000 : Specification guide

Parallel UPS, three-phase, 250 to 3000 kVA*

* Power rating for an N+1 redundant configuration

specified by the battery supplier (0.1 x C10 for a sealed lead-acid battery).

5.1.4 - Operating mode

The charger of each UPS unit shall be sized to recharge the battery rapidly:

a battery with a backup time of[5 / 10 minutes in less than 11 hours] [15 minutes in less than 13 hours] (following a discharge to Pn/2 to recover 90% of backup time).

5.1.6 - Input power factor

The required level of performance is indicated in section 3.5 "Limitation of harmonics upstream of the UPS".

5.1.7 - Voltage regulation

Rectifier/charger regulation shall take into account the ambient temperature of the battery and shall ensure DC output voltage fluctuations of less than 1% irrespective of load and AC input voltage variations (within the limits specified in section 4.1 “Normal AC source”).

5.2 - Batteries

Each UPS unit shall be equipped with its own battery of the …[sealed lead-acid type, factory mounted and wired in

acabinet identical to that of the UPS,] [sealed lead-acid type, mounted on shelves,][vented lead-acid type, mounted on a rack,]... with a service life equal to at least …[5 / 10]… years.

Each battery shall be sized to ensure continuity in the supply of power to the corresponding inverter for at least …[8 / 10 / 15 / 30 / 60…]… minutes, in the event of a normal AC source failure, with the inverter operating at full

rated load, i.e.

 

kVA at a power factor (pf) of 0.8.

Sizing calculations shall assume an ambient temperature between 0° C and 35° C

The UPS shall include devices to ensure:

ωeffective battery protection (see section 8.4 "Protection - Battery");

ωbattery management (see section 9 "Battery management").

5.3 - Inverter

Each inverter shall be sized to supply a rated load of …[ 250 / 300 / 400 / 450 / 500 / 600 ]… kVA at 0.8 pf and shall satisfy the specifications listed below.

5.3.1- Output voltage

ω Rated voltage

[ 380 / 400 / 415 ]… volts rms, adjustable via the user interface (see section 10), within tolerances of +/- 3%.

ω Number of phases

3 phases + neutral + earth.

ω Steady-state conditions

The variation in the rated voltage shall be limited to ± 2% for a balanced load between 0 and 100% of the rated power, irrespective of normal AC input and DC voltage levels, within the limits specified in section 4.1 “Normal AC source” and 5.1.4 “Rectifier/charger - Operating modes and DC-voltage levels”.

ω Voltage variations for load step changes

Output voltage transients shall not exceed ± 1% of rated voltage for 0 to 100% or 100 to 0% step loads. In all cases, the voltage shall return to within steady-state tolerances in less than 100 milliseconds.

ω Unbalanced load conditions

For a load unbalance greater than 30%, the voltage unbalance shall be less than 2% for the phase-to-neutral amplitude and 3 degrees for the phase angle deviation.

5.3.2- Output frequency

ωRated frequency - 50 or 60 Hz.

ωVariations in free-running frequency mode: - ± 0.5 Hz.
