Sizing and general characteristics

Specification guide

Single UPS, three-phase, 160 to 500 kVA (cont.)

All power and control electronics shall be accessible from the front of the UPS.

2.6. Battery maintenance

For safe maintenance on the battery, the system shall include a circuit breaker to isolate the battery from the rectifier, the charger and the inverter. When the battery is isolated from the system, the UPS shall continue to supply the load without interruption or disturbance, except in the event of a normal AC source outage.

2.7. Cold start (normal AC source absent)

The battery shall be capable of starting the UPS if the normal AC source is absent and continue supplying power to the load within the specified backup time. Cold start on battery power shall be possible on the condition that the system shall have started at least once on normal AC power.

3. Sizing and general characteristics

3.2. Rating

The UPS shall be sized to continuously supply a load of…[160/200250 / 300 / 400 / 500] kVA at a power factor of 0.9.

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 0.9.

The battery shall be designed for a service life of …[ 10 / 12 ]…years. It shall be selected and sized correspondingly, for a load power factor of 0.9.

3.4. Types of loads accepted

The UPS shall accept high crest factors (3:1) without derating (kW) to ensure correct operation with computer loads and loads where the leading power factor can reach 0.9.

The total harmonic voltage distortion at UPS output (THDU downstream) shall respect the following limits:

ωTHDU downstream ph/ph ≤ 3% for non-linear loads.

3.5. PFC sinusoidal-current input rectifier

The UPS system shall not draw a level of harmonic currents that could disturb the upstream AC system, i.e. it shall comply with the stipulations of guide IEC 61000-3-4.

The PFC input rectifier using sinusoidal-current IGBTs shall have the following performance levels:

ωTotal harmonic current distortion (THDI) upstream of the rectifier not exceeding 5%,

ωInput power factor (PF) greater than 0.99 from 50% load upwards.

3.6. Output without a transformer

To reduce losses, dimensions and weight, the UPS output shall be of the transformerless type and the neutral shall be recreated electronically.

3.7. Efficiency

Overall efficiency (between the rectifier input and the UPS output) shall be greater than or equal to:

ω94.5% from 50% load to full rated load (In).

3.8. Noise level

The noise level, measured as per standard ISO3746, shall be less than …[75 dBA (for160, 200, 250, 300, 400, 500 kVA)]
