2.2kW 220V Single-Phase Input VFD for a Centrifugal Pump in Indonesia

Real pump and VFD configuration photo used for technical reference; it is not presented as the customer site photo.

Introduction

A pump dealer in Indonesia needed a VFD for a small centrifugal pump where the available site supply was 220V single-phase. The customer wanted smoother starting and variable-speed control, but the key question was whether the motor voltage was compatible with a single-phase input pump inverter.

Based on the information available for this draft, AUSENIST recommended a 220V single-phase input VFD only if the pump motor is suitable for three-phase 220V output. The final selection depends on the actual motor nameplate and wiring connection.

Project Overview

Item	Project Requirement
Country	Indonesia
Customer Type	Pump dealer
Application	Small water transfer and pressure support
Pump Type	Centrifugal pump
Motor Power	2.2kW
Motor Voltage	220V three-phase motor required for this configuration
Power Supply	220V single-phase
Control Requirement	Variable-speed pump control and smoother starting
VFD Model	AUSENIST 220V single-phase input pump VFD, 2.2kW class
Control Method	V/F or pump control mode according to motor data

Customer Requirement

The customer had a common problem in small pump applications: the local electrical supply was single-phase 220V, while many industrial pump motors are three-phase. The buyer needed a compact water pump VFD that could accept the available supply and drive a compatible pump motor.

The requirement was not a universal voltage converter. The motor must be checked carefully. A 380V-only motor should not be treated as suitable for a 220V output drive unless the motor nameplate confirms an appropriate dual-voltage connection.

Technical Challenge

Single-phase input selection is more sensitive than ordinary three-phase input selection. The VFD input side receives single-phase power, while the output side drives a three-phase motor. This can be practical for small pumps, but only within the confirmed rating and motor voltage limits.

The most important technical point is motor compatibility. If the motor is 220/380V and can be connected for 220V three-phase operation, the configuration may be suitable. If the motor is only 380V three-phase, a standard 220V output VFD will not provide the correct voltage.

VFD Selection

Based on the information provided by the customer, the recommended direction is a 2.2kW 220V single-phase input pump VFD with three-phase 220V output. The motor rated current must be compared with the VFD output current before the final model is approved.

AUSENIST should confirm:

• Motor voltage marking, such as 220/380V or 230/400V.
• Motor rated current under the 220V connection.
• Whether the motor is induction or PMSM.
• Required control method: fixed speed, manual speed setting or pressure feedback.
• Ambient temperature and ventilation around the drive.

Recommended Solution

Item	Recommended Configuration
VFD Model	AUSENIST 220V single-phase input pump VFD, 2.2kW class
Rated Power	2.2kW, subject to motor current confirmation
Input	220V single-phase
Output	Three-phase 220V
Control Mode	Pump speed control according to motor and application
Pressure Feedback	Optional if constant pressure is required
Optional Accessories	Pressure sensor, panel switch, external potentiometer or terminals as required

The VFD should be wired by qualified personnel according to the confirmed model manual. After motor data is entered, the installer can test rotation direction, current, acceleration and the required operating frequency range.

If pressure control is required, a pressure transmitter can be added so the VFD adjusts frequency automatically through PID control.

Recommended Initial Parameters

Parameter	Recommended Setting
Motor Rated Power	Set according to 2.2kW motor nameplate
Motor Rated Voltage	Set according to actual motor connection
Motor Rated Current	Use nameplate current for the 220V connection
Maximum Frequency	According to motor and pump rating
Minimum Frequency	Confirm according to hydraulic requirement
Acceleration Time	Set to limit starting shock
Deceleration Time	Set to avoid pressure shock
Start/Stop Source	Keypad, terminal or external control as required

Final settings should be adjusted according to the actual motor nameplate, pump curve and site conditions.

Expected Operating Behavior

The VFD is expected to start the pump more smoothly than direct connection and allow speed adjustment within the confirmed motor and pump range. If used with a pressure sensor, it can also support constant-pressure pump control.

No verified customer running data was provided, so this article does not claim a measured energy-saving percentage or site result.

Engineering Notes

• Do not connect a 380V-only motor to a 220V output VFD.
• Confirm the correct motor terminal connection before commissioning.
• Check motor rated current for the selected voltage connection.
• Leave ventilation space around the VFD, especially in small pump panels.
• Add pressure feedback only when the system actually requires automatic pressure control.

FAQ

Can a 220V single-phase supply run a three-phase pump?

Yes, but only when the VFD and the motor are correctly matched. The VFD output voltage and motor winding connection must be compatible.

Can a 2.2kW pump use a 2.2kW VFD?

It may be suitable if the motor rated current is within the VFD output rating and the pump duty is normal. The nameplate current must be checked.

Can this VFD drive a 380V three-phase motor?

Not as a standard 220V output solution. A 380V motor needs the correct voltage or a separately reviewed voltage configuration.

Is a pressure sensor required?

No. It is required only if the system needs automatic pressure regulation. Manual speed or terminal control may be enough for simple water transfer.
