About the Vertiv Liebert EXL S1 1500kVA UPS
The Vertiv Liebert EXL S1 1500kVA UPS is a floor-standing, transformerless double-conversion online system engineered for mission-critical enterprise infrastructure with no specified runtime window—allowing you to pair it with external battery modules sized to your availability requirements. Rated at 1500 kVA / 1500 kW with a 1.0 output power factor, this unit delivers consistent 400V three-phase output at 50 or 60 Hz (±0.1 Hz in online mode) while accepting 400V three-phase input across 50/60 Hz switchable frequencies via auto-sensing capability.
Built on Vertiv's IGBT-based rectifier and inverter architecture, the EXL-S1-1500KVA achieves up to 96% efficiency in double-conversion mode and up to 99% in ECO mode, minimizing operational heat and energy costs for data center operators, storage architects, and IT procurement teams managing large-scale power resilience. The system includes a static bypass, integrated intelligent battery management with temperature-compensated charging, and forced air cooling for reliable thermal management. Parallel operation is fully supported, enabling both redundancy and capacity scaling across multiple units. Communication is handled via the Vertiv Liebert IntelliSlot with SNMP, Modbus, and BACnet compatibility, integrating seamlessly into existing monitoring and control ecosystems.
Deployment Scenarios
- Tier III and Tier IV data center backbone power protection for large compute and storage clusters
- Financial trading floors and transaction processing centers requiring zero-downtime infrastructure
- Enterprise server rooms and virtualization environments with high-density power demands
- Redundant UPS configurations using parallel capability for geographic or fault-domain distribution
- Facilities requiring 400V three-phase distribution with intelligent power conditioning and remote SNMP monitoring

Frequently Asked Questions about Vertiv Liebert EXL S1 1500kVA UPS
How long will this UPS run my load?
Runtime is load-dependent. Most enterprise UPS at 50% load deliver 8-12 minutes battery on standard internal batteries. Add external battery packs (XL / RBC modules) to extend to 30-60 minutes if you need ride-through past short utility blips.
Can it integrate with VMware vCenter / Veeam for graceful shutdown?
Yes — we ship the SNMP / Network Management Card (NMC) alongside the UPS, plus shutdown agents that integrate with VMware PowerChute, Veeam, NetApp ONTAP, and standard SNMP traps for orchestration platforms.
Do you provide installation and battery disposal?
For Dubai and the wider UAE we offer installation, commissioning, and battery recycling per municipality regulations. For broader GCC we partner with local certified electricians and recyclers — included as an option in the quote.
What is the lead time on larger 10-20 kVA models?
Stocked tier (under 10 kVA): 5-7 business days. 10-20 kVA: 2-4 weeks typically. 20+ kVA modular / parallel systems: 6-10 weeks vendor-side, plus on-site commissioning scheduling. Real numbers quoted with every order.
