INOVANCE MD500ET55G 55kW VFD, Vector Control AC Drive 380V, Built-in EMC Filter, CE Certified for Air Compressor

The INOVANCE MD500ET55G is a 55kW general‑purpose high‑performance current vector frequency inverter from the MD500E series. It is designed to control and regulate the speed and torque of three‑phase 

AC synchronous motors, and represents a technological upgrade over the previous MD380E series.

This model is specifically optimized for screw air compressor applications, featuring sensorless vector control and an integrated EMC filter as standard

Advatages of INOVANCE Vector Inverter

1. High-Performance Sensorless Vector Control

Advanced current vector control delivers excellent torque and speed accuracy without an encoder, reducing system cost and complexity.

2. Exceptional Low-Frequency Torque & Overload Capacity

150% torque at 0.5Hz, 180% overload capacity for 60 seconds – handles heavy start-ups and load fluctuations with ease.

3. Built-in EMC Filter & International Certifications

Integrated EMC filter as standard, fully compliant with CE, UL, cUL, and RoHS for hassle-free global export.

4. Optimized for Air Compressor Applications

Built-in PID control, sleep/wake-up function, and constant pressure regulation – maximizes energy savings and extends component life.

5. Compact Design with Integrated Hardware

Over 30% volume reduction vs. previous MD380E series. Built-in DC reactor and braking unit (standard for 30kW and above) – saves panel space and lowers external BOM cost.

6. Robust for Harsh Environments

Independent air duct design with conformal coating – resists dust, oil mist, and humidity. Ideal for tough compressor room conditions.

7. Rich Communication Options

Supports Modbus-RTU, PROFIBUS-DP, PROFINET, CANopen, and CANlink – seamless integration with existing control systems.

8. Industry-Leading Brand

Inovance is the VFD supplier in China (20%+ market share) with 12 months warranty and ample stock for fast delivery.
