Variable Frequency Drive 4kW 220V, 1/3-Phase In, 3-Phase Out

Variable frequency drive (VFD) delivers precise motor speed control with 220V input and 3-phase output for CNC spindles, pumps, fans, and shop machinery. Designed for stable torque, fast starts, and smooth frequency adjustment, it supports V/F control, vector control, PID regulation, and multiple setting methods. A clear digital display and detachable keypad simplify setup, while optimized PWM control helps reduce noise and electromagnetic interference for cleaner operation.

• Delivers 4 kW (5.5 HP) output with 0–1000 Hz frequency range for wide-speed applications


• Supports 1 or 3 phase 220V input with 3-phase output for compatible motors and CNC systems


• Enables V/F and vector control plus PID closed-loop options for steady torque under load


• Reduces noise using optimized PWM control and heat-dissipating enclosure ventilation


• Protects with overload, over/under-voltage, overheat, short-circuit, stall, fuse, and restart safeguards

Built for demanding workshop and industrial use, this CNC inverter converter is suited to spindle motors and equipment such as milling, drilling, trimming, grinders, conveyors, compressors, ventilators, and pumps. The intuitive digital display keeps parameters easy to read at a glance, and the detachable keypad allows flexible mounting for remote control. Choose it when you need dependable speed regulation, strong low-speed torque, and protection features that help keep downtime low. Grab yours today and dial in smoother motor control.
