EXL S1 — monoblock three-phase UPS 300–1250 kW
Country: USA · Model: EXL S1
Three-phase monoblock UPS for 300–1250 kW loads, double conversion, up to 97% efficiency. It goes into data centers and critical facilities where several units share the load in parallel, and the whole power stage arrives as one factory-built cabinet.

Description
The design is transformerless, with a three-level IGBT rectifier at the input. In dynamic online mode efficiency rises to 99%, which cuts heat in the white space and the load on the cooling plant. Intelligent paralleling coordinates the units working together, so a hall can start with one monoblock and add more later. Power stage and controls sit in one cabinet, so the UPS is installed as a complete monoblock with no module assembly on site. Without an output transformer the cabinet is lighter and smaller than a transformer-based machine of the same rating, which matters when floor loading is limited. Double conversion keeps the critical bus on the inverter, isolated from mains sags and frequency swings.
How to choose
Size the monoblock by the design IT load plus the redundancy scheme, N or N+1 across paralleled units. Where the hall needs no more than 300–600 kW, the high-frequency EXL P1 covers that lower band. For 100–250 kVA rooms the EXM2 monoblock is the smaller step, and plant floors with motor loads and harsh conditions are better served by PowerUPS 6000 Industrial at 6–200 kVA. Choose EXL S1 when a single unit must reach 1250 kW or when dynamic online efficiency weighs on the operating budget.

FAQ
What is the efficiency of EXL S1 in dynamic online mode?
Up to 99%. In double-conversion mode efficiency reaches 97%, and the difference shows up in the cooling load.
What power range does the EXL S1 UPS cover?
Monoblock units are available from 300 to 1250 kW, and several of them can run in parallel on one critical bus.
Does EXL S1 have a transformer?
No, it is transformerless with a three-level IGBT rectifier. Power is 300–1250 kW.
How does EXL S1 differ from EXL P1?
EXL S1 is built as a transformerless monoblock rated 300–1250 kW, with up to 99% in dynamic online mode. EXL P1 is a high-frequency UPS covering 300–600 kW.
Can EXL S1 units be paralleled for redundancy?
Yes, intelligent paralleling coordinates several monoblocks on a shared load, which is how N+1 schemes are built in data centers.
