Protect critical operations with the Liebert NXL – 750 KVA / 675 kW UPS, a high-capacity power protection system for data centers and demanding commercial facilities. Its IGBT-controlled, online double-conversion architecture conditions incoming power and supplies regulated, sine-wave output, with wide input tolerance and robust overload capability.
Each refurbished system from Gruber Power Services is reconditioned, cosmetically restored, and tested in the USA. Our team helps match the UPS, battery system, bypass equipment, and monitoring options to your facility’s requirements.
| Category | Details |
|---|---|
| Power & Technology | 750 kVA / 675 kW at 0.9 power factor; IGBT sine-wave PWM technology; online double-conversion. |
| Input | Rectifier: 480, 575, or 600 VAC, three-phase, 3-wire plus ground. Bypass: 3- or 4-wire plus ground, depending on configuration. Input voltage window: +10%/−15%, with additional sag handling dependent on operating mode. Frequency: 60 Hz ±5 Hz. Input current distortion: ≤5% THDi at full load. Adjustable two-step current limit: 25–125%; adjustable walk-in: 1–30 seconds. |
| Output | 480, 575, or 600 VAC, three-phase, 4-wire, depending on configuration. Voltage regulation: ≤1% with balanced loads and ≤2% at 100% unbalanced load. Voltage distortion: <2% THD with linear loads. Step-load recovery: within ±5% in ≤1 cycle. Overload capability: 110% for 60 minutes, 125% for 10 minutes, and 150% for 60 seconds; 104% continuous operation. |
| Bypass | Integrated static bypass. Bypass voltage range: +15%/−20%; frequency synchronization range: ±5 Hz. |
| Short-Circuit Withstand | Standard ratings: 65 kA at 480 V or 35 kA at 600 V. Optional ratings: 100 kA at 480 V or 65 kA at 600 V. Confirm the supplied unit’s rating and required protective equipment against the site design. |
| Battery System | Compatible with VRLA and flooded lead-acid battery systems. Nominal DC bus: 480 VDC; float voltage approximately 540 VDC. Maximum battery current at end of discharge: approximately 1,845–1,851 ADC, depending on configuration. |
| Controls & Monitoring | Touchscreen operator interface, programmable relays, and emergency power off / remote emergency power off connections. Available communication options include SNMP/web, RS-485/Modbus, and dry-contact I/O. |
| Dimensions & Weight | Approximately 140.5 W × 39.4 D × 76.8 H inches (3,568 × 1,000 × 1,950 mm). Weight: approximately 13,200 lb (5,987 kg). IP20 enclosure with top/bottom cable entry. Confirm the supplied unit’s dimensions, weight, and entry arrangement before installation. |
| Cooling & Heat Output | Cooling airflow: approximately 15,760 CFM. Typical full-load heat dissipation: approximately 200,000–216,000 BTU/hour, depending on line voltage. |
| Operating Environment | Operating temperature: 32–104°F (0–40°C). UPS storage temperature: −13–158°F (−25–70°C); battery limits are separate. Relative humidity: ≤95%, non-condensing. No altitude derating up to approximately 4,920 ft (1,500 m); above this, approximately 1% kW derating per 100 m up to 3,000 m. |
| Option | Details |
|---|---|
