Siemens Sinamics G150 AC Drives

Converters SINAMICS G150 The cabinet versions (versions A and C) were specially designed for such drives with quadratic and constant load characteristics with average performance requirements without the use of energy recovery in the network, such as: pumping and ventilation equipment, compressors, extruders, mixers, mills and other production plants.

Due to the high accuracy of vector control without the use of a feedback sensor, it is possible to solve most of the tasks of use, and therefore it is possible to abandon the additional sensor of the actual speed value. Based on the variety of electrical and mechanical options, an optimal adaptation of the drive system to the relevant requirements is possible.

Version A: All optional linear units (main switch, circuit breakers, contactor, fuses, filters) and sensor elements for monitoring engine operation are available for installation. In this version, a version with parallel connection of power supplies is available.

Version C: compact design with a narrow body without linear technical components, optimal for limited space for placement when locating other components in distribution installations and engine control centers (MCC).
