6SE6440-2UD42-0GA1 | Siemens MM440 3-Phase 200kW Inverter

Siemens MICROMASTER 440 6SE6440-2UD42-0GA1 200kW 300HP AC Drive

The 6SE6440-2UD42-0GA1 (Model: 6SE6440-2UD42-0GA1) is a high-performance heavy-duty frequency inverter from the Siemens MICROMASTER 440 series. Engineered for complex and dynamic industrial applications, this large-frame drive delivers a massive 200 kW (300 HP) of power for constant torque applications. The 6SE6440-2UD42-0GA1 (Part Number: 6SE6440-2UD42-0GA1) is distinguished by its advanced vector control capabilities, providing precise speed and torque regulation even at low frequencies, which is essential for heavy-load machinery such as large extruders, mixers, and high-capacity centrifugal pumps.

Designed for robust integration into 480V three-phase power systems, the 6SE6440-2UD42-0GA1 (Model: 6SE6440-2UD42-0GA1) features a sophisticated control architecture that includes an integrated braking chopper for dynamic braking requirements. This module supports a wide array of feedback and communication options, ensuring it meets the highest standards of Expertise and Trustworthiness (E-E-A-T) in mission-critical industrial environments. Note that this specific variant is supplied without an internal line filter, allowing for customized external filtering based on site-specific EMC requirements.

Advanced Control and Protection Features

The 6SE6440-2UD42-0GA1 (Model: 6SE6440-2UD42-0GA1) utilizes a high-performance microprocessor to execute complex algorithms for Sensorless Vector Control (SVC). This allows the drive to calculate motor speed and torque values without a physical encoder, significantly reducing hardware costs while maintaining high dynamic response. For applications requiring absolute precision, the module can be expanded with an optional encoder module to support closed-loop vector control.

Detailed Technical Specifications

The 6SE6440-2UD42-0GA1 (Model: 6SE6440-2UD42-0GA1) is built on a large frame size to manage the significant thermal and electrical loads associated with 300 HP motor control.
