Variable Frequency Drive (VFD/VSD) SINEE EM730-7R5-3B - Inverter Drive 7.5 kW 380 VAC

The Sinee EM730-7R5-4T Frequency Drive is a high-performance 7.5kW (10HP), 380V AC Variable Frequency Drive (VFD) engineered to deliver precise and efficient motor control for demanding industrial applications. Ideal for woodworking, food processing, packaging, cable production, and fan-driven systems, the EM730 ensures stable performance even in tough operating environments.

Supporting both three-phase asynchronous and permanent magnet synchronous motors, this inverter features vector VF (V/F) and sensorless vector control (SVC) for accurate speed regulation and dynamic load response. It’s built for durability, maintaining stable output under full load at 50°C.

Key Features:

• Power Rating: 7.5kW / 10HP
  
• Input and output voltage are the same, three-phase 380V AC
  
• Output Frequency: Up to 3000Hz for high-speed motors
  
• Control Modes: Vector V/F and Sensorless Vector Control (SVC)
  
• With support for 100 kHz high-speed pulse input for precision applications.
• Special Functions: Built-in rewinding/unwinding support
  
• Wi-Fi connectivity available with optional add-on module (sold separately).
• Flexible Installation: Compatible with 220V single-phase power for 380V inverter setup
  
• User Interface: One-button switching with precise speed control
  
• Construction: Metal baseplate improves vibration resistance and motor stability
  
• Built-in Filter: Close to EMC Level C3
  
• Compatibility: Function codes aligned with EM500 and A90 series
  
• Reliability: Performs under high ambient temps up to 50°C
  

Comprehensive Protection Features:

• Output short-circuit, overcurrent, overload
• Overvoltage, undervoltage, input phase loss
• Overheat and memory failure
• Soft start and current detection abnormalities
• Temperature sensor failure
