The Sinee EM730 is a series of compact, high-reliability Variable Frequency Drives (VFDs) for controlling three-phase AC motors, featuring vector/sensorless vector control, mobile app/Wi-Fi monitoring, integrated protections, high-frequency output (up to 3000Hz), and support for both asynchronous (EM730) and permanent magnet synchronous (EM730E) motors, making it suitable for various industrial applications like food processing, woodworking, and water supply systems.
Key Features & Capabilities:
Motor Compatibility: Drives three-phase asynchronous motors (EM730) and permanent magnet synchronous motors (EM730E).
Control Modes: Offers Vector VF (VVF) and Sensorless Vector Control (SVC) for precise speed and torque control.
Connectivity: Supports Wi-Fi modules and serial ports for debugging and monitoring via mobile app or PC software.
Performance: Handles high-frequency output (up to 3000Hz) and high-speed pulse input (up to 100kHz).
Robust Protections: Includes protection against short circuits, overcurrent, overvoltage, overload, and overheating.
Reliability: Operates without derating at up to 50C ambient temperature.
Special Functions: Features for rewinding/unwinding, built-in C3 level filter, and supports water pump protection (dry-run, reservoir full) in PV models.
User-Friendly: Provides "one-key shuttle" for speed adjustment and LED display for status.
