MARKET DYNAMICS

MARKET DRIVERS

Increasing Demand for Steady Energy Supply UPS for Data Centers Drive Demand for Market Growth

Three-phase UPSs are ideal for mission-critical settings, such as data centers and industrial applications, since they provide a steady energy supply with less energy loss during power conversions, which makes them more economical over time. They also supply power in a more balanced and stable manner. Moreover, modular UPSs offer system redundancy, which speeds up deployment and reduces downtime by allowing defective modules to be replaced without completely stopping the system. Major global and regional players are launching their newest three-phase products to meet the increasing demand for modular UPS.

For instance, in July 2024, Numeric, a Group Brand of Legrand, introduced Keor MP, with ratings between 60 kVA and 200 kVA and scalability up to 1.2 MW. It provides efficiency of up to 96% in a small package. Keor MP integrates advanced Li-ion battery technology to provide a sustainable power solution for a variety of industry needs, including enterprises, number of data centers, IT & ITES, healthcare, commercial, and infrastructure.

MARKET RESTRAINTS

High Installation and Maintenance Costs May Hamper Market Growth

Three-phase UPS has high initial cost and maintenance cost, where the cost of three-phase modular systems is higher than that of two-phase units as they need bigger cabinets to store modules that enable growth. Three-phase UPS are designed for high reliability, scalability, primarily for critical environments that require advanced technologies, scalable architecture, and integration needs, including specialized power modules.  Additionally, ongoing operational expenses such as battery replacements, service contracts all add to the high total cost of maintenance.

MARKET OPPORTUNITIES

Growing Dependence on Data Centers Expected to Create Growth Opportunities

The rapid rise of computing and the strong growth of large-scale and enterprise data centers provide three-phase modular UPS solutions a substantial growth opportunity. Companies in all industries are experiencing demand for cloud computing, large data centers, and extensive colocation facilities. Data centers and IT enterprises are increasingly incorporating modular three-phase UPS systems to safeguard uninterrupted operations.

• In March 2025, CyberPower announced that the sales of its largest 10- and 20-kVA modular three-phase UPS units almost doubled compared to the previous financial year. According to the company’s analysis, the sales increased due to high investment in data centre upgrades, where the investments increased by more than 30% in 2024.

Three Phase Modular Uninterruptible Power Supply (UPS) Market Trends

Adoption of Lithium-ion Batteries for UPS Systems is one of the Latest Trends

The widespread adoption of lithium-ion (Li-ion) batteries as a replacement for traditional Valve Regulated Lead-Acid (VRLA) batteries is the latest trend in the market. Li-ion UPS has higher energy density, longer lifespan, which is two to three times that of VRLA, quicker charging times, and increased tolerance for higher temperatures. It is becoming more and more appealing for modern data centers as it frequently delivers a cheaper Total Cost of Ownership (TCO) due to its lower maintenance, cooling, and replacement frequency requirements.

• In March 2023, Vertiv announced the release of its Vertiv Liebert ITA2 UPS solution, which is the first medium-power lithium-ion rack-mount UPS solution to be introduced in North America. For the new Liebert ITA2 UPS units, customers have the option to buy the lithium-ion battery solution.
