ATO 1HP VFD 110V
The ATO device offers 0.75 kW at 110V input with the ability to output 220V on single or three-phase configurations. It supports 50/60 Hz input and 0-320 Hz output, making it suitable for small machinery like fans, pumps, and tools. Its compact form supports common voltage standards in U.S. workshops. The drive is designed to be versatile across single-phase and three-phase motor setups with standard control interfaces.
Wisoqu 1.5KW Single-Phase VFD
Wisoqu’s VFD provides 1.5KW capacity with 110V single-phase input and 3-phase 220V output. It features a digital display for easy parameter reading and configuration, along with robust plastic housing for impact resistance. The unit targets motor speed control for a range of small to mid-size applications, with emphasis on straightforward operation and reliable performance in typical workshop environments.
Buying Guide
- Compatibility: Confirm the motor’s voltage rating, required current, and phase configuration. Choose a VFD that matches your motor’s rated horsepower and your available power supply (110V vs 220V).
- Input and output configuration: Most models here offer 1P input and 3P output, but verify if dual input options (single or three-phase input) are needed for your setup.
- Frequency range and control: Look for a wide output frequency range (0-4000 Hz where applicable) and control modes (PWM, vector/PID, analog/digital terminals). More advanced control can improve spindle speed stability and process precision.
- Protection and safety: Prioritize drives with overcurrent, overvoltage, overload, and short-circuit protections. A robust enclosure and anti-interference features help longevity in shop environments.
- Cooling and installation: Heatsinks, copper windings, and space for airflow matter for sustained operation. Consider remote control panels if you need access away from the machine.
- Communication and integration: RS485/MODBUS support is beneficial for CNC or PLC integration, enabling remote monitoring and parameter adjustment.
- Size and wiring: Ensure physical dimensions fit your control cabinet and that wiring harnesses match terminal blocks. Keep in mind panel thickness and clearance for heat dissipation.
- Documentation and support: Clear wiring diagrams, parameter lists, and vendor support can reduce setup time and troubleshooting.
