Variable Frequency Drive (VFD/VSD) SINEE EM730-7R5-3B - Inverter Drive 7.5 kW 400VAC

The Sinee EM730-7R5-4T Frequency Drive is a high-performance 7.5kW (10HP), 400VAC 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: 340v - 460v, 3 Phase
  Output: Same as Input Voltage, 3 Phase
• Communications: MODBUS RTU (RS485)
• 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)
  
• 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
  
•  Installation: Can use a 230v Supply for programming the parameters from prior to installation. (Note: this will not drive a motor)

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
