Variable Frequency Drive (VFD/VSD) SINEE EM730-2R2-3B - Inverter Drive 2.2 kW 400VAC

The Sinee EM730-2R2-4T Frequency Drive is a reliable 2.2kW (3HP), 400VAC Variable Frequency Drive (VFD) designed for precise motor speed control in industrial environments. Ideal for woodworking, food processing, packaging, cable manufacturing, and fan-driven systems, this compact VSD (Variable Speed Drive) delivers robust performance, advanced control, and energy savings.

Supporting both three-phase asynchronous motors and permanent magnet synchronous motors, the EM730 offers flexible control methods including vector VF (V/F) and sensorless vector control (SVC). Built for harsh industrial use, it ensures dependable performance at full load in temperatures up to 50°C.

Key Features:

• Power Rating: 2.2kW / 3HP
  
• Input: 340v - 460v, 3 Phase
  Output: Same as Input Voltage, 3 Phase
• Communications: MODBUS RTU (RS485)
• Control Modes: Vector V/F and SVC
  
• With support for 100 kHz high-speed pulse input for precision applications.
• Special Features: Rewinding/unwinding functions
  
• Wi-Fi connectivity available with optional add-on module (sold separately).
  
• User Interface: Detachable keypad with one-button switching
  
• Design: Compact build with integrated EMC filter (near C3 level)
  
• Metal Baseplate: Improves vibration resistance and reduces motor-induced voltage
• Reliability: Stable operation at full load up to 50°C ambient
  
• Compatibility: Shares function codes with EM500 and A90 series for easy upgrades
•  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
