Three-phase UPS Manufacturers-TOP 5 in 2020

According to the 2020 UPS Hardware Market Tracking Report released by Omdia, driven by demand from cloud computing and colocation, the three-phase UPS market continued to grow, reaching approximately 4,910 million in 2019. According to the Omdia report (see Diagram 2), Vertiv, Schneider Electric, KSTAR and other manufacturers ranked among the world's top five three-phase UPS manufacturers.

Established in 1993, KSTAR has maintained a leading position in the three-phase UPS industry for many years. According to the report, KSTAR ranks among the world's top five three-phase UPS suppliers. It has also increased its market share in the 20.1–100 kVA, 100.1–250 kVA and 250.1–500 kVA three-phase UPS segments, demonstrating its comprehensive capabilities and strong performance in this market.

Three-phase power supplies are better suited to higher loads and are commonly used in large-scale installations such as data centres and industrial facilities. Single-phase power supplies are more commonly used for typical loads such as lighting and heating rather than large electric motors. KSTAR offers a range of three-phase UPS solutions from 50 kVA to 1,000 kVA, catering for different installation requirements with floor-standing, rack-mounted and modular options. Our comprehensive solutions can be adapted to the space available for your power protection system.
