220V 2.2KW 3HP VFD Variable Frequency Drive for Single Phase Capacitor Motor, Precise Speed Control, Soft Start Function

Product overview A compact singlephase frequency inverter designed for speed control of singlephase capacitor motors. Provides open loop vector control and V/F control, a wide output frequency range, analog and relay interfaces, PID and multisegment speed programming. Suitable for pumps, fans, conveyors and other small to medium motordriven equipment. Key benefits Precise speed control and smooth starts using open loop vector control (SVC) or V/F control. Works with singlephase capacitor motors without removing motor capacitors. Flexible analog and digital I O for integration with PLCs and external controls. Programmable multisegment speeds and PID support for automated process control. Compact form factor for spaceconstrained control panels. Main specifications Input voltage: singlephase 220V nominal, tolerance typically ±15 percent, 50 Hz or 60 Hz. Output: singlephase 220V (model dependent output can supply threephase 0220V). Output frequency range: 0 to 600 Hz (adjustable). Control methods: open loop vector control (SVC) and V/F control. Starting capability: G type machine starting example 0.5 Hz at 150 percent torque (SVC). Analog input: supports 420 mA or 010 V signals. Relay output: internal relay output available for fault or control signalling. PID function: built in for automated speed regulation. Multisegment speed: 16 programmable speed segments. Carrier frequency: adjustable with level parameter settings. Note on singlephase motors: singlephase motor current can be ; select an inverter 1 to 2 power levels above motor rating for heavy loads.

For heavy or inertia loads choose an inverter with higher power than the motor. For singlephase motors, consider selecting an inverter 1 to 2 power levels above the motor nameplate due to higher starting and running current. Configure analog inputs, PID parameters, relay outputs and multisegment speeds to match application requirements. Carrier frequency and level parameters can be increased for smoother control where needed. Typical applications Water pump and irrigation systems requiring variable flow and soft start to reduce water hammer. Small conveyors and packaging equipment where adjustable speed and multistep operation are needed. Fans, blowers and mixers that benefit from PID control and precise speed adjustments. What makes it stand out Dedicated for singlephase capacitor motors so motor capacitor removal is not . Compact, programmable and feature rich with analog input, relay output, PID and 16segment speed programming. Multiple power models available to match a range of motor sizes from 0.75 kW to 4 kW. Ordering guidance Choose the model that matches or slightly exceeds your motor power and rated current. Confirm input voltage compatibility and consult the wiring diagram before installation.
