QNK 2.2KW 220V 3HP VFD for 3-Phase Inverter
The QNK VFD provides 2.2 kW output with 3-phase 220 VAC operation and a 0-2000 Hz output range. It supports input from both 1-phase and 3-phase 220 VAC sources (±15%). The device emphasizes low-noise operation and reduced electromagnetic interference thanks to PWM technology and careful component compatibility. Control options include V/F and vector modes with digital, analog, and RS485 serial communication (MODBUS) for integration into CNC or automation systems. PID closed-loop tuning improves response and stability in dynamic loads. Suitable for spindle motor control and general 3-phase motor drives in compact installations.
AC 220V/2.2kw VFD 3HP Inverter
This single-phase to three-phase VFD delivers 2.2 kW (3 HP) output with 220V input and a 0-400 Hz output range. Its compact form (about 4.6 x 4.96 x 6.89 inches) suits small enclosure projects and hobby CNC tasks. It emphasizes safety and durability through a copper-wired coil design, effective cooling, and multiple protection layers. The unit is designed for straightforward operation and features a removable control panel for convenient wiring. It comes with a control cable installed inside, with extension cables not included. The VFD is built to handle common spindle and motor loads in light-to-medium duty setups.
PowMr 6500W Split-Phase Hybrid Inverter
The PowMr model supports split-phase output with a built-in 140A MPPT controller and up to 6.5 kW continuous power, suitable for high-demand solar configurations. It enables parallel operation up to six units, allowing expansion to around 39 kW. Dual MPPT tracks maximize energy harvest from PV modules, while CAN, USB, and RS485 enhance system integration. With a higher surge capacity, this unit is appropriate for demanding loads such as large CNC machines or critical systems requiring reliable, high-peak performance. The inverter emphasizes fast switching and robust protection to cope with variable solar input conditions.
VFD 1500W 110V to 220V Motor Speed Controller
This 1.5 kW VFD converts 110 VAC input to 220 VAC three-phase output, enabling effective motor speed control with a compact footprint. The unit features a digital display for parameter monitoring and settings, along with a robust outer shell designed for safety and impact resistance. It suits smaller automated projects, hobbyist CNCs, and pump or fan control where a reliable, space-efficient VFD is needed. The device emphasizes ease of use and straightforward configuration for quick deployment.
VEVOR VFD 3HP 2.2KW
The VEVOR 2.2 kW VFD provides 1-Phase input to 3-Phase output with a 0-400 Hz range. It highlights a 10-layer protection system against overcurrent, overload, and overvoltage, along with phase loss safeguards. The unit emphasizes an intuitive control panel, straightforward parameter tuning, and durable board construction with triple-protection ratings. Its remote-ready design uses a detachable panel for flexible installation, and it targets reliable motor control in workshop and light industrial settings.
Buying Guide: Key Purchase Considerations and Comparisons
- Input and output compatibility: Confirm whether your system requires single-phase or three-phase input and the exact three-phase output requirements. Choose a unit that supports both if you anticipate future changes in the power source.
- Control options and communication: Look for VFDs with RS485/MODBUS or CAN interfaces for integration into automation or CNC control systems. Digital displays and easy parameter tuning reduce setup time.
- Protection and reliability: Prioritize devices with protections such as overcurrent, overvoltage, overload, short-circuit, and phase-loss safeguards. A robust cooling design helps maintain performance under load.
- Protection for sensitive loads: For spindle motors or precision drives, PID closed-loop control and accurate speed regulation improve stability under varying loads.
- Expansion and scalability: If you plan to grow the system, consider products that support parallel operation or dual MPPT (for solar) to enable future capacity increases without replacing the inverter.
- Physical footprint and installation: Check dimensions, heat dissipation, and panel layout. Some models offer removable control panels to allow remote mounting or easier access in tight enclosures.
- Application fit: Match the inverter’s power rating and frequency range with your intended use—industrial motor control, CNC spindle drive, or solar hybrid systems—to ensure reliable performance within your operating envelope.
- Brand and support: Choose a brand with documented specifications, user manuals, and access to after-sales support or replacement parts to minimize downtime.
