Overview
FG3000 series medium voltage variable frequency drive (VFD) cabinet is designed for efficient, precise, and reliable speed control of high-power AC motors. Based on advanced vector control technology, the system supports both synchronous (including permanent magnet synchronous) and asynchronous motors. It integrates control, power, transformer, and switching units into a compact modular structure for easy on-site installation and maintenance.
