4KW Pro Grade Variable Frequency Drive VFD With Advanced Multi Stage Speed And Torque Control Motor Speed Controller For Single To Three Phase 220V 380V Applications Like Fans, Air Compressors, Pumps And Power Tools

4KW Industrial VFD with Multi-Stage Speed & Torque Control
✔️ 1 unit pack; 220VAC input; 0-380VAC output; 20A max

This VFD is a 4KW drive designed for general‑purpose motor control. It converts single‑phase 220V input to three‑phase output up to 380V, enabling multi‑stage speed and torque control for fans, air compressors, pumps and power tools. Pack: 1 unit.

✅ 8 stage programmable multi-stage control for speed or torque mode
✅ Analog input/output: RS485 RTU; 0-5V, 0-10V, 4-20mA, 0-20mA
✅ PID constant pressure control for water supply and wind pressure tasks
✅ Stepless speed regulation and energy saving at low frequency
✅ Protection against overcurrent, overvoltage, undervoltage, overheating, short circuit

💡 What is a variable frequency drive used for in motor control applications?

VFDs let you fine‑tune motor speed and torque for efficient operation. - Controls motor speed and torque for fans, pumps, and compressors - Improves energy efficiency by reducing speed when full power isn’t needed - Soft‑start reduces mechanical stress and electrical spikes - Works with single‑phase input to drive three‑phase motors where supported for general use✝️
