220V/380V VFD Variable Frequency Drive Motor Speed Controller, Single to Three Phase Inverter with Precise Torque Control

Model 310 DC/AC inverter for single phase 220V input and three phase 220V output, available for output power from 0.75 to 4 kW. Output frequency range 0500HZ. Designed for flexible motor control, precise speed regulation, and reliable protection in pump, fan, conveyor, and light industrial applications. Key benefits Flexible control and easy integration: Forward, reverse, start and stop can be driven from the built in panel or from external terminals. RS485 communication allows PLC integration for centralized control. Precise speed and process control: Speed can be adjusted from the panel potentiometer or an external potentiometer. Built in PID function supports constant pressure water supply and other closed loop tasks. Improved braking and protection: Built in brake unit supports an external brake resistor for faster stopping and improved safety. Overload protection helps protect motors and equipment. Better low speed performance: Vector control provides improved low frequency response for stable torque and smooth operation at low speeds. Multi stage and automation ready: Multi stage run and RS485 communication make it suitable for automated sequences and PLC based systems. Main features Model number: 310 Type: DC/AC Inverters Input voltage: 1phase 220V Output voltage: 3phase 220V Output power: 0.754KW Output frequency: 0500HZ Control methods: V/F and vector control Brake module: YES, built in brake unit for connecting brake resistance RS485: YES, communication protocol compatible with PLC Functions: forward, reverse, start, stop via panel or external terminals; panel or external potentiometer speed adjustment; PID function for constant pressure; multi stage run Optional external control panel is available but not included in the package Overload protection and standard inverter protections Additional product notes Size: 1phase 220V Color: 3phase 380v_1.5kw Designed for improving conversion and control efficiency without changing motor wiring for common three phase motors Typical applications Water supply and pressure control: Use the PID function for constant pressure systems and variable speed pump control to reduce wear and energy use. Conveyors and material handling: Smooth start, stop and reversible control with brake support for controlled indexing and safe stopping. Fans, blowers and light machine tools: Precise speed regulation with V/F or vector control for consistent process results and quieter operation. Compatibility and installation tips Compatible with three phase motors driven from a 3phase 220V output. Confirm motor power rating matches the inverter output power range of 0.75 to 4 kW. Use the external brake resistor with the built in brake unit when fast stopping or inertia loads are expected. RS485 connection enables PLC control and monitoring. An optional external control panel can be used for remote operation but is not included. This inverter provides flexible control options, robust braking and reliable communication for a wide range of industrial motor control needs.
