CyberPower SM20KPM 3-Phase online UPS provides long-lasting power backup for data closets, transportation and infrastructure, and emergency systems. With parallel redundancy capability, the Modular UPS (3-Phase) is ideal for critical applications in server rooms, data centers, industrial factories, and power generation plants that require high capacity, high reliability, and extended runtimes. With integrated IGBT technology and intelligent DSP-based control, the Modular UPS (3-Phase) 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 Modular UPS (3-Phase) includes the advantage of scalability, allowing a capacity increase of up to 400Kva of the total load to the existing backup power system. Each independent power module is designed for parallel operation with active current sharing to achieve N+1 power redundancy. In the event that a single power module fails, the load is automatically distributed among the remaining modules to avoid the risk of single point failure. Each power module is hot-swappable for convenience, easy power expansion and system maintenance without disrupting the connected load--significantly increasing system reliability.
