The LCI-converter (load commutated inverter), SINAMICS GL150, is designed for single-motor applications with variable and constant torque characteristics in power ratings up to 85 MW (Higher ratings on request). Available in air- and water-cooled designs and capable of 2Q or 4Q operation. Commonly used for variable-speed operation as well as for start-up operation of large synchronous motors and generators and with speeds ranging up to approx. 7000 rpm.
The converter power section of the air-cooled SINAMICS GL150 has been upgraded to provide an optimized solution in the lower power range (6p/6p up to 5 MW; 12p/12p up to 9 MW).
The new innovative design is characterized by:
Economic and highly-efficient drive design
Arc fault- and earthquake tests proved design
Accessibility of the low-voltage section, even during operation
An special "line-side fuses" retrofit option integrated in the design
Compact design and highest power density
Easy plant integration due to compact design and highly flexible configuration
Simple operator control with the user-friendly operator panel
High reliability and ruggedness through the use of extremely robust thyristor technology and fuseless design, combined with an intelligent response to external disturbances
Hassle-free integration into higher-level automation systems through analog and digital interfaces and PROFIBUS DP
Designed for synchronous motors in an almost maintenance-free design

Most commonly found in the Oil & Gas industry with applications that require a starting converter or where the power required is over 30 MW with large compressors or pumps, especially common in some LNG applications.
Primarily used in the Chemical & Petrochemical industry for the more complex applications with power requirements over 30 MW, such as really large pumps.
Available for various ship applications and is often used in main propulsion, boosters and shaft generator applications.
Used in numerous pump and fan applications in the power generation industry, one example of a pump application are boiler feed pumps. It can also be used in starting applications for generators.
Especially appropriate for use in starting blast furnace applications and with operation of wire rod mills.
An Integrated Drive System ensures fast installation, safe operation, and higher than 99% availability at the largest blast furnace at Kunming Iron & Steel in Yunnan.
