High-Frequency UPSutilizes IGBT-based high-frequency rectification technology and operates without an output isolation transformer. By boosting the internal DC bus voltage to approximately 800V, it achieves high power density in a compact, lightweight footprint. This design delivers superior input power factor (≥0.98), low harmonic distortion, and energy efficiency of up to 96%. Ideal for data centers, server rooms, and telecommunications facilities where space optimization and energy savings are top priorities.
