SINAMICS G180 cabinet units - air-cooled and liquid-cooled

Обзор

Example of SINAMICS G180 air-cooled converter cabinet unit

With its SINAMICS G180 cabinet units, Siemens is offering a drive system on which all line-side and motor-side components are integrated extremely compactly into a specially designed cabinet enclosure. This approach minimizes the effort and expense required to configure and install them.
SINAMICS G180 cabinet units are available in air-cooled and liquid-cooled versions.

SINAMICS G180 converter cabinet units are available for the following voltages and power ratings:

¹⁾ Higher outputs available on request.

Global use

SINAMICS G180 converter cabinet units are manufactured in compliance with relevant international standards and regulations, and are therefore suitable for global use (see technical data).

Air-cooled converter cabinet units

Air-cooled converter cabinet units are equipped with an ingeniously designed, highly efficient air guidance system which is quiet in operation.

Liquid-cooled converter cabinet units

These specially designed liquid-cooled versions of the SINAMICS G180 converter cabinet unit are extremely quiet in operation. Closed control cabinets in degree of protection IP54 or higher make these liquid-cooled converters suitable for applications in harsh environmental conditions.

The advantages of the liquid-cooled version as compared to the air-cooled version are as follows:

• Very low thermal loading of switch rooms
• Can be used almost anywhere, even in atmospheres harmful to machines, thanks to the IP55 degree of protection (IP54 with display in cabinet door)
• Reliable even at higher ambient temperatures up to 55° C thanks to optimal cooling effect
• Reduced noise emission through elimination of the cooling ventilation
• Improved efficiency
• The water-conveying parts of the cooling system are made of stainless steel (V2A), making it resistant to almost any water quality
