3007 represents the frame size and rated power of 37 kW. 403 indicates 3-phase 380–500 V input and no built-in EMC filter. The number 4 stands for 4-quadrant operation with regenerative braking function. 00 means standard firmware without additional fieldbus modules or STO safety functions.

It accepts 3-phase AC 380–500 V input at 50/60 Hz. The output voltage ranges from 0 to 400 V and the output frequency from 0 to 150 Hz, with a rated output current of 72 A. It supports V/F open-loop control and sensorless vector control. The inverter can continuously operate at 125% rated current and withstand 150% rated current for 60 seconds.

It is equipped with 6 digital inputs, 2 digital outputs, 1 relay output, 2 analog inputs and 2 analog outputs. Comprehensive protection functions include overcurrent, overvoltage, undervoltage, overtemperature and earth fault protection. It features IP20 protection class. The operating ambient temperature is from 0 °C to +45 °C. Its total weight is approximately 28 kg.

This unit adopts full 4-quadrant operation. It feeds braking energy back to the power grid to reduce energy consumption, and external brake resistors are not required. It provides excellent dynamic performance to support fast acceleration and deceleration, ideal for equipment with frequent start and stop cycles.

Thanks to sensorless vector control, encoders are not needed, which simplifies wiring and lowers overall costs. The rugged industrial structure ensures stable long-term operation. An external EMC filter is required if compliance with EMC Class C2 is needed.

It is used to drive 37 kW three-phase asynchronous motors. Typical applications include cranes, hoists, downhill conveyors and heavy-duty material handling equipment. It is also suitable for fans, pumps, compressors and general industrial machinery that requires rapid deceleration and energy recovery.

This 37 kW model delivers higher power for heavier loads compared with 3005-403-4-00 (22 kW), 3004-403-4-00 (15 kW) and 3003-403-4-00 (11 kW). All the above models are 4-quadrant inverters for dynamic and regenerative loads. In contrast, the 1-quadrant model 3003-403-1-00 has no regenerative braking function and is a more economical choice for standard fans and pumps.
