About the Vertiv Liebert EXL S1 1000kVA UPS
Lead with management interface: SNMP/Modbus/TCP — remote monitoring is table-stakes. The Vertiv Liebert EXL S1 1000kVA UPS delivers carrier-grade power continuity through a transformer-free, double-conversion online topology that achieves up to 97% efficiency in standard mode and up to 99% in ECO mode. Built on IGBT-based active front-end rectifier technology, this floor-standing cabinet accepts 400V three-phase input (50/60 Hz auto-sensing) and maintains output voltage stability at 400V three-phase with less than 3% input current THD at full load. The unit operates at unity power factor (1.0) with full 1000 kVA / 1000 kW output capacity, conforming to IEC 62040-1, IEC 62040-2, and IEC 62040-3 (VFI-SS-111) standards.
Designed for IT infrastructure teams and data centre operators, the EXL-S1-1000K-RD supports both lead-acid VRLA and lithium-ion battery options, enabling flexible capacity planning across mission-critical environments. Redundancy architecture includes N+1 and parallel configurations (multiple units in parallel), ensuring zero-downtime deployments. Native communication via SNMP, Modbus RTU/TCP, and Liebert IntelliSlot provides deep visibility and integration with existing enterprise management platforms. Output frequency precision holds ±0.1 Hz in inverter mode, guaranteeing equipment compatibility across regional power standards.
Enterprise Deployment Scenarios
- Data centre rack power distribution where transformer-free efficiency reduces cooling overhead and operational cost per kVA
- Financial trading floors and mission-critical transaction systems requiring dual-conversion stability and sub-millisecond transfer times
- Healthcare and life-sciences facilities leveraging N+1 redundancy to meet continuous-availability compliance mandates
- Multi-building campus infrastructures using parallel-unit scaling to avoid single-point failures across distributed IT loads
- Hybrid energy environments where ECO mode (up to 99% efficiency) minimizes grid draw during partial-load periods

Frequently Asked Questions about Vertiv Liebert EXL S1 1000kVA 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.
