ZF310 Series Single Phase 220V Input To 3 Phase 220V Output Variable Frequency Drive

Single Phase 220V Input to 3 Phase 220V Output Variable Frequency Drive

The ZF310 Series Single Phase 220V VFD is a compact variable frequency drive designed to convert single-phase 220V AC input into three-phase 220V AC output for controlling three-phase AC motors.

With a power range of 0.75kW to 5.5kW, the ZF310 provides adjustable motor speed, smooth acceleration and deceleration, high starting torque and multiple motor protection functions. It is particularly suitable for industrial machines and equipment where only a single-phase 220V power supply is available but a three-phase 220V motor needs to be controlled.

• Power Range: 0.75–5.5kW
• Input: Single-phase 220V AC
• Output: Three-phase 220V AC
• Control Modes: V/F Control and Sensorless Vector Control
• Starting Torque: Up to 150% at 0.5Hz
• Frequency: Adjustable output frequency
• Motor Speed Control: Variable-speed operation
• Detachable Keypad: Convenient parameter setting and monitoring
• Multiple Protection Functions: Overcurrent, overvoltage, overload, overtemperature and other protections
• Compact Design: Suitable for machine control panels and limited installation spaces
• OEM Compatible: Suitable for integration into industrial machinery

The ZF310 Series Single Phase 220V VFD provides a practical solution for applications where the available electrical supply is single-phase 220V, while the motor is a three-phase 220V AC motor.

The VFD converts the incoming single-phase AC power through its internal rectification and inverter stages and generates a controlled three-phase output for the motor.

This allows users to operate three-phase motors in locations where a conventional three-phase power supply is not readily available.

The drive also provides adjustable motor speed, controlled acceleration and deceleration, and configurable motor protection parameters.

The main configuration of this series is:

Power Supply → Single Phase 220V AC → ZF310 VFD → Three Phase 220V AC Motor

This configuration is especially useful for: Small industrial workshops / OEM machinery / Machine tools / Small production equipment / Pumps / Fans / Conveyors / Mixers  / Packaging machines

Before selection, the motor nameplate voltage and rated current should be confirmed to ensure the motor is suitable for three-phase 220V operation.

The ZF310 supports sensorless vector control for applications requiring improved torque performance and speed response.

Compared with basic V/F control, sensorless vector control can provide better motor torque performance, particularly at low speed.

The drive can deliver up to 150% starting torque at 0.5Hz, depending on motor characteristics and actual application conditions.

This makes it suitable for machinery that requires stronger starting performance.

Direct starting of an AC motor can produce high starting current and mechanical impact.

The ZF310 allows users to set the acceleration time so that the motor gradually increases its speed rather than starting abruptly.

This can help:

Reduce mechanical shock

Reduce belt and coupling stress

Improve starting stability

Reduce sudden torque impact

Extend equipment service life

The deceleration time can also be adjusted according to the machine's inertia and stopping requirements.

The output frequency of the ZF310 can be adjusted according to the required operating speed.

For example, a motor designed for 50Hz operation can be operated at different frequencies within the appropriate application range.

This provides flexible speed control for equipment such as conveyors, fans, pumps and mixers.

The actual maximum frequency and operating range should be configured according to the motor and machine manufacturer's requirements.

The ZF310 incorporates multiple protection functions to improve system reliability.

Depending on the configuration, protection functions can include:

Overcurrent protection / Overvoltage protection / Undervoltage protection / Motor overload protection / 

Drive overtemperature protection / Short-circuit protection / Stall protection / Phase-loss protection / 

Other programmable fault protections

These functions help protect the drive and motor during abnormal operating conditions.

The ZF310 is designed for applications where control-panel space is limited.

Its compact structure allows the VFD to be integrated into:

Machine control cabinets

OEM equipment

Pump control systems

Fan control systems

Packaging machinery

Industrial automation equipment

The detachable keypad provides convenient access to parameters during installation and commissioning.

Suitable for speed control of small machine tools and workshop equipment where single-phase 220V power is available.

Variable-speed control can be used to adjust pump operation according to flow or pressure requirements.

Adjust fan speed according to airflow demand and operating conditions.

Control conveyor speed and provide smooth starting and stopping.

Provide adjustable motor speed for different mixing processes.

Suitable for small packaging and production machines requiring adjustable motor speed.

The compact design and flexible control functions make the ZF310 suitable for integration into customized machinery.

When using a single-phase 220V input VFD, the input current is higher than that of an equivalent three-phase input VFD because the input power is supplied through only one phase.

Therefore, for applications near the upper end of the power range, VFD selection should be based not only on motor power but also on:

• Motor rated current
• VFD rated output current
• Input power capacity
• Load type
• Starting torque requirement
• Overload requirement
• Operating duty

For heavy-duty applications, please provide the motor nameplate so that the appropriate VFD model can be selected.
