Sinamics G150 Clean Power frequency converter

The Sinamics G150 Clean Power frequency converter from Siemens is designed to provide an energy-efficient drive with high power rating for fans, pumps and compressors or extruders, mixers and mills. The converter also reduces low-frequency harmonic effects on the system and thus fulfils the high requirements for current and voltage quality placed on mains supplies.

The Sinamics G150 Clean Power combines the advantages of 6-pulse rectifier technology with an integrated passive compact line harmonics filter (LHF compact). With this filter, the converter meets stringent standards such as IEEE 519. Pulse frequency components in line current are also avoided with the LHF compact. With the LHF concept mode of operation, active components are not required and there is no need for complex transformer technology. This reduces wear and tear, increasing availability, and power losses are low, which in turn has a positive effect on the efficiency of the converter.

Due to the integration of the filter, the converter has a compact design and the line fuses of the converter also protect the LHF compact. Circuit breaker and power contactor disconnect the converter and filter safely from the mains power supply, avoiding the need for double installation of fuses, circuit breakers and contactors and for an additional line reactor.
