The Siemens frequency converter SINAMICS S120 series is capable of performing various demanding drive control tasks in the industrial field, providing users with simple and effective drive control processes. The Siemens frequency converter SINAMICS S120 series can be configured with a power module to provide stable power supply for the Siemens frequency converter drive control system.

Siemens frequency converter SINAMICS S120 power module

1. Basic power module

The basic power module of the Siemens frequency converter SINAMICS S120 series is applied in situations where energy feedback is not required. When braking energy is generated in the equipment, users need to configure the braking unit and braking resistor. The basic power module can provide stable power supply for users, while also saving space and improving efficiency. It can be used in situations with only a small amount of braking energy.

2. Active power module

The active power module of the Siemens frequency converter SINAMICS S120 series can absorb energy from the power grid and also feed back energy to the grid. It can also perform reactive power compensation, and the active power module can also use braking units and braking resistors. The bus voltage of this module is controllable, which can ensure the stability of the bus when the voltage in the power grid fluctuates, especially suitable for use in situations with a large amount of braking energy.

3. Feedback power module

The feedback power module of the Siemens frequency converter SINAMICS S120 series is applied in situations with a large amount of braking energy. The energy generated by braking can be fed back to the power grid. The use of braking units and braking resistors can enable the system to effectively brake in the event of a power grid fault. The feedback power module saves space for users during installation and improves efficiency during use, making it particularly suitable for applications that require a large amount of braking energy.

The Siemens frequency converter SINAMICS S120 series is powerful and easy to operate, providing users with an ideal solution for motor drive control.
