Siemens upgrades Sinamics G120 modular drive power

October 7, 2014 - Siemens upgrades Sinamics G120 modular drive with a higher power density and space-saving frame size. The higher power density is attributable to the new PM240-2 power module. The re-engineered drive range is now available in three voltage versions for connection to 200 V, 400 V and 690 V lines. The second generation devices are even more resistant to line fluctuations, thanks also to an integrated DC link inductor. The IP21 degree of protection makes the drives drip-proof, allowing them to be mounted outside a control cabinet, even in a damp environment. Siemens offers seven frame sizes with powers ranging from 0.37 kW (kilowatts) to 250 kW depending on requirements.

The Sinamics G120 generation enables the drives to be mounted side-by-side without derating, reducing not only space requirements but also the cost of control cabinet construction. In order to lower heat levels in the control cabinet, the Sinamics G120 features the innovative push-through cooling concept in addition to needs-based ventilation. Furthermore, filtered and unfiltered devices have the same footprint. The new Siemens drives have optimized connections on the line and motor sides to simplify commissioning and maintenance work. Siemens also supplies the shield plates at no additional cost.

The user can combine the power unit with the appropriate control unit and other optional components such as operator panels to meet the requirements of the application. The control units have extended functions, and are characterized by precise, reliable vector control and basic positioning capabilities. All the new Sinamics G120 drives also have a comprehensive, integrated safety concept ranging up to PLe/SIL3. Sinamics G120 is suitable for pumping, ventilating and compressing applications, as well as moving and processing applications. The devices are designed to meet a diverse range of industrial and business requirements, such as those in general mechanical engineering and the automotive, textile, packaging and chemicals industries.
