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.
