Converters

Siemens Automation and Drives has developed the Sinamics G150 converter for high-performance pumps, fans and turbocompressors.

At full power, the Sinamics G150 causes a noise level of typically 72 db, making soundproofing measures unnecessary. The device additionally features simple handling, particularly during system planning, product procurement, installation and commissioning, as well as for the HMI and servicing concept.

Sinamics G150 controls the speed of low-voltage asynchronous motors with powers between 75 and 800 kW. The converter's design makes it particularly suitable for use in pumps, fans and tur-bo compressors. These applications are standard drive tasks for quadratic load torques which can be handled by vector control without speed feedback.

The space required by Sinamics G150 is up to 50% less than with conventional devices. If the power connection components are fitted in a central low-voltage system, space savings of up to 70% are even possible. Despite its compact design, the internal cable connection area is generously dimensioned, permitting problem-free connection even with large cable cross-sections.

If required, the degree of protection can be upgraded on site, for example from IP20 to IP54, without changing the required space.
