VFD Inverters

Compact VFD inverters (120W–750W) that take single-phase 220V input and deliver three-phase 220V output for precise speed control of 3-phase motors. Features V/F control, soft start/stop, forward/reverse, knob + keypad setting, and multiple protections—ideal for conveyors, packaging, woodworking, and general automation.

220V Single-Phase to Three-Phase VFD Inverters (120W–750W)

These compact 220V VFD inverters accept a single-phase 220V supply and provide a three-phase 220V output to drive and regulate the speed of 3-phase induction motors in the 120–750W range. With V/F control, on-panel keypad, and a speed knob, they deliver smooth acceleration, stable low-speed torque, and reliable braking for everyday industrial automation.

Power Range & Compatibility

Power: 120W–750W
Input: AC 220V single-phase
Output: AC 220V three-phase (U/V/W)
For: Standard three-phase 220V induction motors

Speed & Control

Frequency range: 0–99 Hz (typical) for precise speed regulation
V/F control with soft start/soft stop to protect motor and load
Forward/Reverse switching and quick stop
On-panel keypad, speed potentiometer (VR), and terminal control
RS485/Modbus (where available) for external control and monitoring

Quick Wiring Overview

Input: Connect single-phase AC 220V (L/N) to the AC input terminals
Output: Connect motor leads to U/V/W for 3-phase 220V output
Control: Use digital inputs (e.g., FWD/REV), analog VR (0–5V/0–10V, model-dependent), and common (COM)

Always follow the user manual for terminal definitions, fusing, and grounding practices.

Key Features
