## Overview

The QNK 3KW 4HP 220V VFD Converter transforms single-phase input into a stable 3-phase output with up to 2000 Hz frequency control, ideal for CNC spindles and industrial motors. Featuring advanced PWM technology, it ensures low noise and electromagnetic interference while offering comprehensive protection against overload, voltage irregularities, and overheating. Built with durable copper coils and a heat-dissipating design, this inverter drive supports RS485 MODBUS communication and PID control, making it a versatile, reliable choice for professional-grade motor speed management.

## Description

QNK 3KW 4HP 220V AC 14A VFD Converter Single to 3 Phase Inverter Variable Frequency Drive CNC Spindle Motor Speed Controller

## Features

- 【3KW (4HP) Variable Frequency Drive 】Input: 1-phase 220 VAC (+/- 15%), 0-14 A, and 50/60 Hz. Output: 3-phase 220 VAC, 0-14A, and 0-2,000 Hz.
- 【Low-Noise Operation & Low Electromagnetic Interference】 The PMW control technology and a component compatibility design allow this VFD for low-noise operation and low electromagnetic interference.
- 【V/F Control & Vector Control】 The VFD frequency setting mode includes digital setting, analog setting, serial communication setting (RS485 communication port, adopting standard international MODBUS main circuit control), PID setting (advanced calculus PID closed-loop arithmetic, quick responding speed, and high suitability), etc.
- 【Improved Safety & Durability】QNK VFD features protective functions for overload, fuse, over voltage (DC voltage>400V) or under voltage (DC voltage<200V), restart, stall, short circuit, and overheat. Moreover, it comes with copper coil internals and a nonflammable exterior for durability and a multi-grid design with enough cooling space between the electronic components and the case for fast heat dissipation.It also can prevent dust, water mist entering the circuit board section effectively.
- 【Wide Application】The VFD can be used in various types of equipment such as Spindle Motors, CNC Routers, Milling Machines, Pumps, Compressors, Grinders, among others.
- 【Attention】Please Note:1.This VFD surpport external resistor!!! If your motor is heavy load, pls choose a higher power level VFD or contact sales for model selection suggestion. 2.The VFD can’t be used as a power source for other equipment, or to drive a motor with a supply voltage lower than 80V. 3.Do not connect the VFD’s output terminals with capacitive loads.4.Choose a VFD with a larger power output when operating heavy equipment like the crane and compressor, e.g.,a 5.5 Kw motor should be connected to a 7.5 Kw VFD. 4.If a generator is used to power the VFD, ensure that the generator's output voltage level is within +/-15%.
- 【Customer Service】If there is an error code in the product and you do not know how to operate,or other questions of this product,pls feel free to contact us. Customer Support Team will help you as soon as we can within 24h.
