Product Introduction:

The new Liebert EXL S1 is a reliable, efficient and flexible high‑frequency all‑in‑one UPS product. Both the rectifier and inverter adopt three‑level technology, achieving a double‑conversion efficiency up to 97%. Smart parallel operation improves efficiency under light‑load conditions for outstanding operating‑cost performance, reducing total cost of ownership (TCO) and CO₂ emissions.

The newly‑introduced Dynamic On‑Line Mode delivers an operating efficiency up to 99 %, while ensuring IEC 62040 Class 1 power quality and high availability. Covering a power range of 300‑1200 kVA, Liebert EXL S1 brings further optimizations in efficiency and power density.

For users pursuing high return‑on‑investment, such as colocation data centers and cloud‑computing service providers, Liebert EXL S1 saves considerable space to deploy more IT servers or shrink the overall computer‑room footprint, thus cutting construction costs.

Its Dynamic On‑Line Mode boosts UPS system efficiency to 99 % without compromising system reliability. Under this mode, the inverter can supply power to loads at any time in compliance with IEC 62040 Class 1 standard, delivering identical power quality as the conventional double‑conversion online mode.

Liebert EXL S1 is equipped with a 9‑inch color touch‑screen for intuitive and flexible local query and operation. It supports remote device management via Vertiv platforms including Liebert Nform, SiteScan and Trellis. Communication protocols enable compatibility with third‑party BMS and DCIM systems. The Liebert EXL S1 series UPS readily supports lithium‑battery solutions from Vertiv and other third‑party vendors.
