Product Title

INOVANCE MD310T3.7B VFD 3.7kW 3PH AC380-440V Modbus RTU Compact Frequency Inverter

1. Product Overview

The INOVANCE MD310T3.7B belongs to MD310 series compact general-purpose VFD. It adopts sensorless vector control and V/F control to adjust the speed and torque of three-phase asynchronous motors. With built-in braking unit and standard RS485 Modbus RTU communication, it supports closed-loop PID control and multi-speed operation. Rated for 3-phase 380~440V AC power supply, widely used for fan, pump, textile, conveyor and general machine speed regulation.

2. Core Advantages & Key Features

✅ Sensorless Vector & V/F Control Excellent low-speed torque performance, stable speed regulation for ordinary asynchronous motors. ✅ Built-in Braking Unit Directly connect braking resistor without extra braking module, save cabinet cost and space. ✅ Standard Modbus RTU via RS485 Easy networking with PLC, HMI and sensors for centralized monitoring. ✅ Built-in PID Regulator Realize constant pressure, constant flow and tension closed-loop automatic control. ✅ Max Output Frequency up to 300Hz Suitable for high-speed spindle and small high-speed machinery. ✅ High Efficiency ≥96.5% Great energy-saving effect for fan and pump loads. ✅ Rich Protection Functions Overcurrent, overvoltage, undervoltage, overheat, overload, short-circuit protection. ✅ Compact Structure IP20 Small dimension, easy panel installation inside electrical cabinet.
