Ziehl-Abegg has introduced EC fans with Active Power Factor Correction (PFC) for data centers, significantly improving electrical performance. These fans achieve power factors between 0.95-0.99, which lowers reactive power and decreases losses in cables and transformers, directly reducing operational expenses where cooling makes up 30-40% of total energy consumption.

Additionally, PFC reduces RMS current, prolongs the lifespan of electrical components, and maintains high power factor even under partial loads. Compliance with IEEE 519 and IEC 61000-3-2 standards prevents overheating and enhances system stability, crucial for the reliability of Tier III and IV data centers. The cumulative effect on Power Usage Effectiveness (PUE) is notable in large installations, while facilitating compliance with energy quality requirements for certifications like Uptime Institute and LEED.
