SINAMICS G150

Siemens
SINAMICS G150 cabinet units have been designed for variable-speed drives in machine building and plant construction.
They have been specially tuned to the requirements of drives with quadratic or constant load characteristics with medium performance requirements without regenerative feedback.
The control accuracy of the sensorless vector control is suitable for most applications, and additional actual speed value encoders are therefore superfluous.
SINAMICS G150 offer an economical drive solution which can be matched to the respective customer requirements by a wide range of components and options.

Features
SINAMICS G150 are ready-to-connect AC/AC converters in a standard control cabinet.A comprehensive range of options permits adaptation to respective requirements.They are available with cabinet widths from 400 mm upwards in intervals of 200 mm, in various degrees of protection up to IP54, and with two design versions.
Version A offers sufficient space for all available options. Different designs permit the power supply and motor connections to be located at the top or bottom. This results in high flexibility for the plant installation.
Version C is an extremely space-saving version envisaged for applications where the power supply components are accommodated in a central low-voltage distribution and need not be provided again in the control cabinet.The user-friendly AOP30 operator panel is fitted as standard in the cabinet door for both versions.
