The Siemens Drive Technologies Division is increasing the upper power limit of its Sinamics G150 series of converters from 1500 to 2700 kilowatts (kW). These low-voltage converters are designed for applications without regenerative feedback, for example those that involve moving, pumping or compressing substances. Due to the variable-speed drive operation with frequency converters, energy is saved - in the case of pumps, fans and compressors by up to 70 percent. The cabinet units can be connected to 2-winding transformers. In order to minimize low-frequency harmonic effects, 12-pulse operation on a 3-winding transformer is also available as a standard feature. The use of IGBT power semiconductors and a special cooling concept ensure that the converters are quiet and compact in all available degrees of protection from IP20 to IP54. It is easy to commission and operate the devices thanks to the AOP 30 advanced operator panel and the Starter PC tool. Their rugged yet simple design makes the devices reliable and easy to maintain. When ordering the product, users can configure the standard options to suit their individual applications.
