The Vevor variable frequency drive is designed for precise speed control of three-phase motors in CNC routers, milling machines, drilling machines, pumps, compressors, grinders, elevators, and other equipment. It supports single-phase or three-phase 220V input and delivers three-phase 220V output with a 0-400Hz output frequency range. An intuitive display with easy-to-use buttons and a detachable panel helps simplify setup and operation. Built-in protections against overcurrent, overload, overvoltage, and phase loss help promote safe, reliable performance. Its flame-retardant ABS housing and ventilated cooling design support durability during extended use.
