The Siemens 6SL3120-1TE21-0AA4 is a compact single-motor module classified under the SINAMICS series. It is engineered to deliver reliable performance with a nominal output current rating of 9 amperes and a continuous operation current of 7.7 amperes. This module supports a current of 10 amperes for brief durations, provided a 40% duty cycle is maintained. It can manage a maximum current output of 18 amperes, providing versatility in various applications.

This unit outputs 0 to 71.7% of the DC-link voltage while supporting a capacitance of 110 microfarads. To protect against voltage fluctuations, the overvoltage limit is set at 820 volts with a ± 2 percent margin, while the undervoltage threshold is fixed at 380 volts, also with a ± 2 percent tolerance.

The module requires a control power input of 24 volts DC and has an operational range extending from 20.4 to 28.8 volts. It can produce a rated power output of 4.8 kilowatts and achieve a maximum pulse frequency of 4 kHz, rising to 16 kHz at reduced performance settings.

Cooling is managed through a fan integrated into the design, ensuring the unit operates within safe temperature limits. At 5 kilograms, the 6SL3120-1TE21-0AA4 module is compact yet powerful, suitable for a variety of motor control applications in industrial settings.
