ATO 3hp VFD 110V Input To 220V Output
This VFD supports a 120V single-phase input and provides a 220–240V output in single or three-phase configurations. It delivers 3 hp (2.2 kW) for AC motors, with an input range of 110V AC ±15% and an output range that accommodates 0–320 Hz. The drive is designed for common American power supplies and recognizes 50/60 Hz input. Applications include fans, pumps, and power tools, enabling motor speed control while preserving motor efficiency and lifetime. Safety features and protections are important considerations when selecting a drive for commercial or home workshop use.
Wisoqu VFD 110VAC In, 3-Phase 220VAC Out
The Wisoqu drive provides single-phase 110VAC input with a 3-phase 220VAC output, suitable for speed control of motors up to 1.5 kW. It features a digital display for straightforward parameter setup and reading, with a robust plastic housing designed for impact resistance. This model emphasizes safe operation and accurate motor speed adjustment, making it a practical choice for compact workshop setups where precise RPM control is needed for tools or small equipment.
XCFDP 220V 2.2kW VFD Single Phase To 3 Phase
Designed for 220V single-phase input with 3-phase 220V output, this 2.2 kW (3 HP) drive uses copper windings for safety and durability. It features a compact footprint and an efficient cooling design for steadier operation. Protective functions such as over-current and over-voltage safeguard both the drive and the motor, while the included control panel wiring simplifies setup. Note that some batches may not display the brand logo, but technical parameters remain consistent across units.
HY HUANYANG 110V Single-Phase To 3-Phase VFD
This HY HUANYANG model converts 110V single-phase input to 3-phase output for motors up to about 3 HP. It supports MC H3 (mcah3) functionality and RS-485 communication, enabling remote monitoring and control. The device also accommodates remote potentiometer speed control and remote start/stop, making it suitable for applications requiring integrated control systems, such as automated manufacturing or remote equipment management.
ATO 5hp VFD 1-Phase To 3-Phase
For higher power needs, this ATO drive handles 5 HP with 1-phase input and 3-phase output, delivering 0–1000 Hz output frequency and capable of converting 1-phase 220–240V to three-phase outputs for compatible motors. It’s designed for a broad range of equipment including fans, pumps, and power tools, and provides robust performance for more demanding workshop or small industrial environments where single-phase power must drive larger three-phase machinery.
ATO 10hp VFD Single to 3 Phase
The ten-horsepower VFD from ATO accepts a single-phase 220–240V input and delivers three-phase output to drive larger motors. With RS-485 communication and a broad output frequency range up to 1000 Hz, this drive suits applications requiring significant motor performance, such as larger fans, pumps, or industrial tools. Suitable for users upgrading existing single-phase supply to run three-phase equipment, this model balances higher power needs with reliable control and flexibility.
Buying Guide: Key Purchase Considerations
- Motor compatibility: Ensure the motor’s rated HP and current align with the VFD’s output. Mismatches can cause overheating or insufficient torque.
- Input/output voltage: Confirm your input is within the VFD’s acceptable range (e.g., 110V, 120V, or 220V) and that the output is suitable for your motor (single-phase input, three-phase output).
- Protection and safety features: Look for over-current, over-voltage, short-circuit, and thermal protections. Multi-protection designs reduce risk in industrial environments.
- Control and communication: Some models offer RS-485 or other interfaces for remote monitoring. For automated setups, MC H3 and remote start/stop options can be important.
- Cooling and enclosure: Adequate cooling helps maintain performance in continuous operation. Consider enclosure type and mounting space in your lab or workshop.
- Install and wiring simplicity: Removable control panels and clearly labeled terminals simplify installation. Confirm included cables and wiring lengths if needed.
- Parameter ranges: Compare output frequency (Hz) and acceleration/deceleration settings. Higher Hz ranges provide greater motor speed control but may require tuning for specific motors.
- Reliability and support: Check manufacturer documentation, warranty terms, and available customer support to ensure long-term usability.
- Noise and vibration: Some drives may produce more audible noise or vibration depending on load and cooling. Assessing your workspace for these factors is prudent.
- Cost vs. features: Higher HP models offer more torque and headroom but at a higher price. Balance your needs with budget and space constraints.
When selecting a single-phase to three-phase VFD, focus on the motor’s torque requirements, the acceptable voltage range of your supply, and the level of remote control you need. For hobbyist projects, a mid-range 2–3 HP unit with straightforward setup may suffice. In workshop or light-industrial settings, higher-power models with protective features and RS-485 support provide the best long-term reliability and control options.
