ATO 20 hp 480V Three Phase VFD
The ATO 20 hp 480V VFD inverter is designed for three-phase 480V systems. It offers a rated input current around 32 A and a 0–400 Hz output frequency range, enabling precise speed control for larger motors. The device supports automatic energy-saving operation and automatic voltage regulation, helping prevent nuisance trips due to over-current. It is suitable for industrial fans, pumps, and processing machinery requiring consistent 3-phase performance at higher voltages.
ATO 15hp VFD 220V Input to 3-Phase Output
This ATO model accepts single-phase 220V input and provides three-phase 0–240V output at 50/60 Hz, making it a practical phase-converter style drive for converting standard 120V–240V outlets into 3-phase capability for motors up to about 15 hp. Ideal for workshops and small manufacturing lines that rely on 3-phase motors but have only single-phase power available. Applications include fans, pumps, and machinery tools requiring reliable phase conversion.
MOLLOM VFD 15KW 20HP
The Mollom VFD provides 15 kW (20 hp) output with 0–3000 Hz range, suitable for CNC spindle motors and high-speed tooling applications. It supports both single and three-phase inputs and offers RS-485 communication and MODBUS compatibility. The drive emphasizes robust anti-jamming performance, a user-friendly digital display, and a detachable design for remote operation. This makes it a strong choice for precision speed control in mills, lathes, and CNC setups where tight motor control is critical.
HY HUANYANG GT Series VFD
The HY HUANYANG GT Series VFD offers 11 kW (15 hp) output and can accept single-phase or three-phase 220–230V input. It supports mcah3 function and RS-485 communication, with remote potentiometer speed control and remote start/stop capabilities. The model is designed for easy integration with standard motors, pumps, fans, and automation equipment, providing reliable speed regulation with practical wiring and control options for mid-sized installations.
LAPOND 15KW 20HP VFD
The LAPOND drive handles 1-phase to 3-phase input at 220V with 0–400 Hz output up to 15 kW (20 hp). It includes Mach3 support, RS-485 communication, and remote potentiometer compatibility. The unit emphasizes stable operation, low noise, and a compact footprint suitable for small to medium industrial machines. It is appropriate for 3-phase motors in pumps, fans, and light manufacturing equipment where flexible input power is a factor.
Buying Guide: Key Considerations When Selecting a 15 HP 3-Phase VFD
- Voltage compatibility: Choose between 220V single-phase to 3-phase input or 480V three-phase input based on your facility power. Some models support both, but check start-up configurations and wiring requirements.
- Output current and protection: Ensure the VFD’s continuous and peak current ratings align with motor stall current. Look for features like automatic current limiting and over-current protection to reduce nuisance trips.
- Control options: RS-485, MODBUS, remote potentiometer, and switch inputs impact integration with existing controls. Decide whether you need network communication or simple local control.
- Frequency range: Higher output frequencies enable faster spindle speeds or tool changes for CNC applications. Confirm the maximum Hz and the smoothness of acceleration/deceleration.
- Protection and diagnostics: Overload, overheating, short circuit, and motor fault protections extend equipment life. Some models offer energy-saving modes and automatic voltage regulation for steady performance.
- Motor compatibility: Verify that the VFD is suitable for your motor type (induction vs. servo) and that the motor’s rated voltage and enclosure type match the VFD’s output.
- Programmability and compatibility: Consider ease of programming, available presets for common loads, and whether the VFD supports features like vector control or V/F control for better torque at low speeds.
- Physical footprint and installation: Check dimensions, heatsinking, mounting hardware, and available cooling. Larger frames may require additional enclosure space and ventilation.
- Support and warranty: Access to technical support, documentation, and warranty terms matters for uptime and maintenance planning.
