Key Features
4-quadrant regenerative design. Braking energy is fed back to the grid to reduce power consumption. External brake resistors are not required, which simplifies system layout and lowers maintenance cost.
Superior dynamic performance. Sensorless vector control ensures high torque output at low speed and fast response for acceleration, deceleration and direction change.
Simple installation and wiring. Encoders are not needed, effectively cutting down wiring work and overall project cost. The industrial-grade structure guarantees long-term reliable operation.
Flexible expandability. An external EMC filter can be equipped to meet EMC Class C2 requirements. Optional fieldbus modules are available for network connection.
Typical Applications
This inverter is widely used to drive 37 kW three-phase asynchronous motors. It is ideal for cranes, hoists and other lifting equipment with potential energy loads. It also fits downhill conveyors and heavy material handling equipment with large inertia and frequent braking. Besides, it can be applied to industrial fans, pumps, compressors, mixers, machine tools and other general manufacturing machinery that requires speed regulation and energy recovery.
