A 625kVA UPS is a high-capacity power backup system designed to provide reliable, continuous power to critical equipment during outages or fluctuations in the main power supply. The “kVA” rating refers to kilovolt-amperes, a measure of apparent power, which indicates the system’s capacity to handle loads. For a 625kVA UPS, this typically translates to supporting substantial power demands, often seen in data centers, industrial facilities, or large commercial buildings.

These systems usually include battery backup to maintain power during short-term outages and can be paired with generators for extended downtime. Depending on the design, a 625kVA UPS might deliver around 500-625kW of real power (assuming a power factor of 0.8 to 1.0, common in such systems), though this varies by manufacturer and model. Features often include surge protection, voltage regulation, and scalability options, such as modular designs that allow expansion.

625KVA Liebert EXL S1 delivers an outstanding double conversion efficiency of up to 97%, which further increases up to 99% with the dynamic online mode, consequently reducing operating costs and energy dissipation (kW) to a minimum. This significantly minimizes the consumption of the cooling system, providing an overall TCO reduction and rapid payback time.

Furthermore, through its intelligent ECO mode efficiency and the intelligent paralleling feature Liebert EXL S1 can optimize efficiency even at partial load achieving additional superior cost savings.
Dynamic Online mode: No more availability tradeoff with efficiency
Dynamic Online mode is the latest high efficiency mode of operation offered by Vertiv, developed for those that do not want to trade off any level of availability for incremental gains in efficiency.

Dynamic Online mode enables operating efficiency up to 99% without sacrificing availability. In fact, while in this mode, the inverter can instantaneously assume the load and maintain the output voltage within the IEC 62040 Class 1 specification, thus offering the same level of availability typically achieved in a double conversion operating mode.

Dynamic Online mode is therefore able to combine the superior availability of a double conversion operating mode with the excellent energy cost savings of a high efficiency mode for a reduced total cost of ownership.

Liebert EXL S1 features a transformer- free design with full IGBT three-level double conversion technology, providing extraordinary savings on installation and running costs, while at the same time delivering first class load protection.

Liebert EXL S1 also features a full IGBT three-level rectifier allowing for electrical infrastructure cost saving, reducing the size of gensets, circuit protection, cabling and transformers.

Flexibility and Compatibility UPS 625KVA

Liebert EXL S1 can be fully adapted to meet diverse system requirements in terms of power capacity and redundancy allowing for different system designs, thus ensuring maximum flexibility:
– Output Power Factor up to 1
– No power derating from 0.4 lagging to 0.7 leading
– Optimum space/power ratio
