5.0SPECIFICATIONS

5.1Rating

The kVA and kW ratings and the nominal voltages and currents for continuous operation are listed on the unit nameplates (inside Operator Control Panel door) and on the System One-Line Diagram. The rated output power envelope of the UPS is illustrated in Figure 70. The UPS is rated to deliver rated kVA and rated kW at 0.8 lagging power factor (pf), or 0.9 lagging pf for some models. However, the UPS will operate connected loads with power factors ranging from 0.7 lagging through 1.0 (unity).

Connected load kW and kVA are both displayed on the LCD screen when the UPS is powering the load. The approximate connected load power factor may be easily calculated by kW ÷ kVA = pf.

For load power factors between 0.7 lagging and the rated power factor (usually 0.8 or 0.9), the full kVA rating of the unit is available. However, above the rated pf the kW rating will become the limit- ing factor. Note that some models are specifically rated for a 0.9 lagging output power factor.

For loads with power factors below 0.7 lagging or with leading power factors, the UPS output is kVA limited and the UPS System may not meet all of its output performance specifications. Contact Lie- bert Global Services at 1-800-LIEBERT to request assistance for these applications.
