The 6SL3121-1TE31-3AA3 from Siemens is a single motor module that comes in a clever book-size format, facilitating easy integration into various setups. This unit is rated for a 600 V DC input and provides a substantial output voltage of 400 V AC with a current handling capacity of 132 A. It achieves a power output of 107 kW, allowing it to drive motors efficiently in diverse conditions.

A key feature is its external air cooling mechanism that ensures optimal operational stability. The module can handle a pulse frequency of up to 4.0 kHz, making it suitable for applications requiring precise motor control. The DC link voltage can range between 510 V and 720 V DC, enabling flexibility in system design.

For powering electronic components, this unit features a 24 V DC power supply with a variation tolerance of -15% to +20%. It supports long motor cables, extending up to 100 meters with shielding and 150 meters without shielding. The inclusion of an M8 screw for protective earth connection aids in ensuring safe operations.

Operating between 0 °C and 40 °C without derating, the device is well-suited for typical industrial environments, with the capability to be installed at altitudes up to 1,000 meters above sea level. Higher elevations are possible though they may require derating to maintain performance.

Additionally, the module is equipped with advanced safety features, including Extended Safety Integrated and DRIVE-CLiQ, which enhance fault tolerance and reliability during operation.
