Product Description
Model: MD200T3.7B 3.7KW
Product Overview
The INOVANCE MD200T3.7B is a 3.7kW general-purpose vector inverter designed for industrial three-phase motor control. It supports both induction motors and permanent magnet synchronous motors (PMSM), delivering precise speed and torque regulation through advanced sensorless vector control (SVC) technology. With a built-in braking unit, RS485 Modbus communication, and comprehensive protection features, the MD200T3.7B is a reliable and cost-effective drive solution for fans, pumps, conveyors, compressors, and general automation equipment.
Product Advantages & Core Features
- Sensorless Vector Control (SVC) — High starting torque (150% at 0.5Hz), accurate speed regulation (±0.5%), smooth low-speed operation
- Energy-Saving Algorithm — Built-in V/F optimization reduces power consumption by 20%–60% in fan and pump applications
- Built-in Braking Unit — Integrated braking chopper supports rapid deceleration with external braking resistor, ideal for hoisting and positioning
- Comprehensive Protection — Overcurrent, overvoltage, undervoltage, overload (150%/60s), overheating, phase loss and short-circuit protection; conformal-coated PCBA
- Flexible I/O & Communication — 5 DI / 2 AI / 1 relay output / 1 transistor output / 1 AO; RS485 Modbus RTU standard
- Advanced Built-in Functions — PID control, 16-speed presets, simple PLC, wobble frequency, S-curve accel/decel, DC braking, flying start, AVR
- Easy Commissioning — Detachable LED keypad with parameter copy, intuitive parameter grouping, auto-tuning
