ATO 10hp VFD Single to 3 Phase, 10hp Inverter Converter
- Input: 1 phase 220V-240V AC; Output: 3 phase AC 0–input voltage; Frequency: 0–1000 Hz
- 34 amps, RS485 enabled phase converter for single-phase power supply
- Best for: General-purpose conversion to drive 3-phase motors like fans and pumps
This VFD is ideal for workshops needing a reliable single-to-three phase solution without upgrading to three-phase power. Choose this if your setup uses standard 220–240V mains and you want broad frequency control for slow to high-speed motor performance. A potential limitation is the 34A current rating, which may constrain larger loads on multiple motors simultaneously.
ATO 10HP VFD Single Phase Input & Output
- Input: 220–240V single phase; Output: 1-phase to 1-phase with 0–500 Hz
- 49A rated drive with 7.5 kW capacity
- Best for: Small machines needing precise speed control in single-phase systems
Best for users who require straightforward single-phase to single-phase speed control on modest loads. It supports flexible design and provides respectable torque response. Limitations include adopting 1-phase to 1-phase operation, which may not satisfy heavy loading scenarios that truly need 3-phase outputs.
LAPOND 11KW VFD 1-Phase to 3-Phase Converter
- Input: 1-phase/3-phase 220VAC; Output: 3-phase 220VAC, up to 42A
- 11 kW (15 HP) rated; outputs 0–400 Hz with RS-485 and remote controls
- Best for: Larger single-phase sources powering 3-phase CNC or spindle motors
Choose LAPOND when you need higher power and broader control options. It’s well-suited for applications requiring RS-485 communication and remote potentiometer control. A caveat is its larger physical size and mass, which matters for compact installations.
ATO 10hp Three Phase Input Output VFD 480V
- Input: 3-phase 480V; Output: 3-phase 0–input voltage; Frequency up to 400 Hz
- 17 A rated current; energy-saving and voltage-regulation features
- Best for: Industrial networks with 480V supply needing reliable high-voltage VFD
Best for facilities that run on high-voltage 480V services and require stable, automatic current limiting to prevent trips. This option is less suitable for standard 240V single-phase outlets and higher voltage equipment, so ensure compatibility with your electrical system before selecting.
HY HUANYANG GT Series 11KW VFD
- Input/Output: 220 VAC single or 3-phase inputs; RS-485 and remote control options
- 11 kW (roughly 15 HP) capacity with flexible input modes
- Best for: Applications needing versatile input configurations and smart wiring
HY HUANYANG’s GT Series stands out for versatility. It supports several input modes and offers RS-485 communication, making it suitable for setups that may evolve from single to three-phase or require remote monitoring. A limitation is that setup complexity can be higher for users unfamiliar with VFD parameter tuning.
MOLLOM VFD 7.5KW 10HP
- Output: 0–3000 Hz; Input: 220V; 32A max current
- Supports single or three-phase input; RS-485 port; MODBUS compatibility
- Best for: CNC spindle motors and speed-controlled machinery
MOLLOM’s VFD offers a wide high-frequency range and robust digital/analog terminals. It’s best for users who need precise speed control with advanced control features. A potential limitation is that higher-frequency operation can demand careful motor tuning to avoid resonance in some spindle setups.
ATO 5hp 1-Phase to 3-Phase VFD
- Input: 220–240V single phase; Output: 3-phase 0–input voltage
- 19.2 A; 0–1000 Hz frequency range
- Best for: Upgrading small single-phase loads to 3-phase capability
Choose this for smaller tools or machines that must transition from single-phase supply to three-phase operation without upgrading power infrastructure. It’s affordable and straightforward but may lack some advanced control features found in higher-end models.
QNK 7.5KW 10HP VFD for CNC Spindles
- Input: 1-phase/3-phase 220 VAC; Output: 3-phase 220 VAC up to 2,000 Hz
- RS-485 with MODBUS support; low-noise PWM control
- Best for: CNC spindle motors requiring tight speed control and communications
QNK offers a compact, feature-rich option for CNC applications and general-purpose speed control. It’s stronger on communication and control logic, but users should ensure the 220 VAC supply matches their facility’s power distribution and that the motor and drive ratings align with spindle requirements.
Buying Guide
What to check before buying
- Input voltage compatibility: Ensure your facility’s power is compatible with the VFD’s single-phase input (commonly 220–240V) or 480V for industrial systems.
- Output needs: Confirm whether you need single-phase output or true 3-phase output, and verify the motor’s HP and current ratings align with the VFD’s capabilities.
- Current rating: Match the drive’s amperage to the motor’s full-load amps to avoid overloading the VFD.
- Control features: Look for RS-485/MODBUS for remote monitoring, programmable speed control, and remote start/stop options.
- Physical size and installation: Larger 11 kW–15 HP models require more space and proper mounting clearance.

Common questions
- Do these VFDs require three-phase input? Some models accept single-phase input and provide three-phase output, while others require three-phase input for full performance.
- Can I use a VFD with a CNC spindle? Yes, several models support high-frequency output and RS-485 communication suitable for CNC control.
- What about control wiring? Many VFDs include digital/analog terminals and RS-485 for remote control and monitoring.
- Is higher frequency always better? Not always; higher frequencies enable faster response but may require more careful motor tuning and shielding from EMI.
- Are there size considerations? Yes; higher power ratings typically mean larger drives and need for robust mounting and cooling.
FAQ
- What is the advantage of a single-phase input VFD? It lets you run 3-phase motors from standard residential or business power without dedicated 3-phase supply.
- Can I connect multiple VFDs to the same single-phase circuit? It’s possible but requires careful power budgeting to avoid tripping breakers or undervoltage conditions.
- Do these drives support remote start/stop? Most listed options include remote controls or RS-485/Modbus interfaces for remote operation.
- How do I choose the right VFD for a CNC spindle? Prioritize high-frequency output, robust PWM control, and reliable feedback interfaces (RS-485 or MODBUS).
- Is installation by a professional recommended? For higher voltages and industrial-grade drives, professional electrical installation is advised to ensure safety and compliance.
