【Product Parameters】 This 220v 7.5kw Variable Frequency Drive (VFD) supports single-phase or three-phase input to three-phase output.Input voltage: AC 220V (180 - 250V), output voltage: 220V; Input frequency: 40-60Hz, Output frequency: 0-400Hz; Input current: 35A, Output current: 50A.\n【User-Friendly Control】 The VFD features an intuitive and clear control panel and frequency knob for easy operation. The panel is removable for remote control capabilities.\n【Comprehensive Protection】 Features overload (DC>400V), low-load (DC<200V), overheating, overvoltage, fuse, restart, short-circuit, and phase-loss protections. Integrated PWM noise-reduction technology and a built-in cooling fan ensure stable operation and extended durability of the variable frequency drive.\n【Wide Applications】 Compatible with CNC machines, CNC engraving machines，compressors, pumps, grinders, and other 3-phase converter applications. please avoid working in damp environments where water droplets or metal objects may enter, as this can cause short circuits.\n【Professional Support】 It doesn\\\'t support external resistors. For heavier motor loads, please choose a higher-powered VFD for best results. For setup guidance or motor compatibility, please feel free to contact us. We will provide professional advice as soon as possible.
