Three-phase voltage and frequency stabilized power supply

This power supply employs advanced sinusoidal pulse width modulation (SPWM) IGBT high-frequency inverter technology and features an internal AC–DC–AC topology, which completely eliminates grid interference and ensures a pure output waveform. It offers a wide voltage and frequency regulation range, high accuracy, lightweight construction, compact size, and an output equipped with an isolation transformer; thus, it can seamlessly integrate with generators to form a high-quality uninterruptible power supply (UPS) system.
