3. Product Specifications & Features
3.1 Core Specifications
The TMEIC ARND-4045 B2 is optimized for medium-voltage, high-power motor control, with 450 kW rated power and 3.3 kV input/output voltage fitting heavy-industry needs (e.g., steel mill conveyors). Its 0–120 Hz output frequency range supports both low-speed torque control (e.g., heavy-load startup) and high-speed operation (e.g., centrifugal compressors).
Sensorless vector control ensures precise speed regulation (±0.5% of rated speed) without external encoders, reducing installation complexity. The ≥96.5% efficiency minimizes energy loss, while the comprehensive protection suite guards against electrical faults—critical for preventing downtime in continuous-production industries.
3.2 Key Features
- High Power Density: 450 kW output in a compact enclosure, saving plant floor space compared to traditional medium-voltage VFDs.
- Stable Load Adaptability: Sensorless vector control maintains consistent speed/torque under fluctuating loads (e.g., mining conveyor load changes).
- Energy Efficiency: ≥96.5% efficiency cuts energy costs, ideal for 24/7 operation in heavy manufacturing.
- Robust Protection: Multi-layer fault protection (overcurrent, overheating) extends drive and motor lifespan.
- Easy Integration: Standard Modbus and optional Ethernet ports enable seamless connection to PLC/DCS systems, simplifying remote monitoring and control.
