CyberPower OLS3S20KE 3-Phase online UPS provides long-lasting power backup for data closets, NAS and servers, DVRs/surveillance systems, POS systems, and transportation and infrastructure. With parallel redundancy capability, the Online S (3-Phase)UPS is ideal for critical applications in server rooms, data centers, and industrial factories that require high reliability, high stability, and extended runtimes.
With integrated IGBT technology and intelligent DSP-based control, the Online S (3-Phase) UPS produces less input total harmonic distortion (THDi) and achieves higher power efficiency up to 98% in Economy Mode, making it the most efficient UPS in the industry. Higher operating efficiency equates to lowered BTU heat dissipation and lowered idle power consumption, resulting in an operating expense reduction and a lower carbon footprint.
The Online S (3-Phase) UPS includes the advantage of scalability, allowing the addition of up to 4 UPS to the existing backup power system. With its advanced parallel architecture, it allows each UPS to evenly share the power consumed by rear end loads, thus achieving N+1 power redundancy protecting against UPS failure and significantly increasing system reliability.

Three-phase Power Input
Three-phase power is commonly used in large businesses and is also increasingly popular in power-hungry, high-density data centers. Instead of going through a hassle to convert from an existing single-phase installation, the three-phase allows smaller, less expensive wiring, guaranteeing power protection and high efficiency for equipment designed to operate on three-phase.
In order to enhance power continuity and power protection for data center servers, power redundancy is realized by adding an additional power backup to evenly share the power consumed by rear end loads, thus achieving the highest protection against UPS failure while significantly increasing system reliability.
