SINEE EM730-5R5-3B - Frequency Drive 5.5 kW 380 VAC

The Sinee EM730-5R5-4T Frequency Drive is a robust 5.5kW (7.5HP), 380V AC Variable Frequency Drive (VFD) engineered for superior motor speed control across demanding industrial applications. Perfect for woodworking, food processing, packaging lines, cable equipment, and fan-driven systems, the EM730 delivers precision, reliability, and energy-efficient performance.

Designed for both three-phase asynchronous and permanent magnet synchronous motors, this high-performance inverter supports vector VF (V/F) and sensorless vector control (SVC). Built to perform in tough environments, it maintains reliable operation under full load up to 50°C.

Key Features:

• Power Rating: 5.5kW / 7.5HP
  
• Input Voltage: Three-phase 380V AC
  
• Output Frequency: Up to 3000Hz for high-speed motor applications
  
• Control Modes: Vector V/F and SVC
  
• Pulse Input: High-speed 100kHz pulse input
  
• Special Features: Rewinding/unwinding functionality
  
• Connectivity: Wi-Fi module and mobile app support for remote diagnostics
  
• Installation: Can be linked to 380V inverter using a 220V single-phase supply
  
• User Interface: Simple one-button switching with precision speed control
  
• Design: Compact housing with integrated EMC filter (near C3 level)
  
• Metal Baseplate: Vibration-resistant metal substrate reduces motor-induced voltage
  
• Reliability: Operates consistently at 50°C ambient temperature
  
• Compatibility: Same function codes as EM500 and A90 series for plug-and-play replacement
  

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
