Product details
Description
The QNK 3.2KW 3HP 220V AC 11A Variable Frequency Drive is an advanced electronic motor speed controller designed to seamlessly convert single-phase 220V power into a robust three-phase output. Ideal for machinists, hobbyists, and workshop owners, this inverter powers 3-phase CNC spindle motors, milling machines, lathes, and water pumps directly from standard household or workshop power lines.
Built with cutting-edge Pulse Width Modulation technology, it ensures low operational noise and minimal electromagnetic interference for smooth, reliable performance. It supports versatile operation modes including digital setting, analog control, PID closed-circuit calculations, and RS485 MODBUS communication.
Equipped with comprehensive safety mechanisms such as overload, over-voltage, under-voltage, short-circuit, and overheating protection along with copper coil interiors, this VFD delivers exceptional durability and efficiency for demanding industrial applications.
How to use
- Mount the VFD securely in a well-ventilated area with adequate clearance for heat dissipation.
- Connect the single-phase 220V power supply to the input terminals and your 3-phase motor to the output terminals according to the wiring diagram.
- Configure the desired maximum frequency and parameters using the digital display panel before initiating operation.
